Decline in Biodiversity
Biodiversity is important in ecosystems because every life form works together in order for them to function. When these ecosystems are disrupted or altered, or even lacks biodiversity, it poses major threats to all the life forms in it, whether it happens quickly or over a long period of time. When we lack biodiversity, our ecosystems become unstable, which in turn makes them more vulnerable to disasters and they cannot contribute to our well being. Although policy makers may be faced with challenges, many considerations need to be taken into account to preserve biodiversity and to protect these areas so that these ecosystems can function properly and prosper.
When we hear the word ‘biodiversity’, it pretty much explains itself. It is the amount of variation of life forms within a given biome, ecosystem, species, or even the entire plant. Many considerations need to be taken into account to preserve biodiversity and to protect these areas so that these ecosystems can function properly and prosper. With respect to the ecosystem and biodiversity, we need to remember that once our natural resources run out and when most ecosystems are destroyed, it is very hard to restore it to what it was. We need to consider our well being, as well as all the other organisms that we share the earth with. We use biodiversity all the time, whether it is direct or indirect. In order for us to live happy and healthy, we need a healthy ecosystem and it is our job to preserve it as much as possible so we can have functional communities or living organisms. When we lack biodiversity, our ecosystems become unstable, which in turn makes them more vulnerable to disasters and they cannot contribute to our well being. Some natural cycles associated with the ecosystems and biodiversity is the natural chemical cycles that occur including oxygen, carbon, nitrogen, phosphorus, sulfur and hydrologic cycles. In each of these cycles, nutrients are recycled back into the ecosystem to be reused.
The issue of biodiversity loss can be addressed globally, nationally, locally. Globally, loss of biodiversity is linked to rise in disease. Many species that are known to prevent disease are slowly dying off while the species that contribute to disease are surviving. (Example: Mosquitoes that transmit the West Nile Virus to humans and animals) Nationally, bio-invasion is becoming a problem. Bio-invasion is the increasing number of invasive species that are being introduced into the United States which are affecting the species that are already here. For example, zebra mussels are threatening to wipe out native mussels and consume large quantities of phytoplankton, while becoming a problem to the water treatment facilities by blocking pipes. “According to the US Coast Guard, zebra mussels are nearly impossible to eradicate one they’ve taken hold in an environment. They are extraordinarily hardy, and any poison that could exterminate them would damage the surrounding habitat” (Sherwood, 2011). Locally, greenhouse gases are causing the destruction and demise of coral reefs by excess carbon dioxide leading to ocean acidification. . “Coral reefs are always in a balance. Acidification makes it harder for the building forces to build and easier for the eroding forces to erode” (Schlesinger 2008). Personal: Many people agree that we, as humans, are responsible for ensuring that future generations get to experience a sustainable life on Earth. Biodiversity also contributes to personal enjoyment by providing natural beauty and outdoor recreation.
Policy makers are often faced with challenges in resolving, identifying and/or dealing with biodiversity. These problems include: understanding natural capital and integrating them into decision-making, responding efficiently and properly to this issue, people resisting to change and society adjusting to new rules and lifestyle changes. Viewing biodiversity loss by evaluating the values and ethics can lead one to understand how they have contributed to the manifestation of biodiversity loss. Through a value perspective, nature has experienced a decline in how valuable it is to humanity, which has caused carelessness and ignorance. Through an ethical perspective, one can identify the relationship, whether it is weak or strong, that humans have to the environment that can be directly linked to biodiversity loss. Humans must take responsibility for their actions and feel an ethical need to make it a better place.
Liu, J. (2003) Effects of household dynamics on resource consumption and biodiversity 421, 6922; ProQuest Biology Journalspg. 530 retrieved from http://search.proquest.com.proxy-library.ashford.edu/biologyjournals/docview/204551270/13DE2F69B901BE3C4F9/3?accountid=32521
This article explains how human population size and growth rate are drivers of biodiversity loss. As human population rates grow, there are more greenhouse gas emissions and resource consumption. The article studied and compared the human population size in 76 hotspot households and 65 non-hotspot households. In hotspot countries, they found that the number of households was much higher between the years 1985-2000. Households in non-hotspot areas were equal. This article also claims that the growth rates in households will increase over the next 15 years. If the household size had stayed the same during these years, there would have been 155 million less households by the year 2000; and by the year 2015, there will be as many as 233 million more households in hotspot countries. In hotspot countries, the increase in population size limits the efforts to conserve biodiversity which degrades the ecosystem.
A policy recommendation that can be the best way to address biodiversity loss through the policy process is the zero-deforestation policy that requires suppliers to produce merchandise such as timber, beef, soy, palm oil and paper fiber in a way that has minimal impact on natural forests and climate. Not only does deforestation affect the climate negatively, but it also affects the well being of over 1.5 billion people that rely on the forest for food, as well as habitats for many animals and plant species that play key roles in the environment. Some of the laws that protect U.S. forests and stop illegal wood products from entering the marketplace include the Wilderness Act, Lacey Act and Roadless Rule. The zero deforestation policy is set to be achieved by the year 2020 and many members of the Consumer Goods Forum (CGF) announced that they would work together to attempt to achieve this goal. Due to the growing population and demand for food and fresh water, it is inevitable that the planet will experience rapid climate change. Although many people are on board with implementing the zero deforestation policy, there are some challenges that prevent it from moving along. “It was there that the US government announced it would help companies move towards the zero net deforestation target through the launch of a partnership with the CGF. Unfortunately, little else has been done to address the challenge of managing deforestation associated with commodity sourcing head-on, leaving companies to grapple with two key issues” (Sonenshine, 2013) The two issues aforementioned include 1) the lack of data showing that sourcing specific wood alternatives can drive further deforestation and 2) identifying agreed areas for protection because of the limited movement by the roundtables.
Benefits of zero-deforestation policy (for humans and other species) include: less carbon in the atmosphere, more oxygen, less emissions from fires/clear cutting/logging/development, more food, fresh water, clothing, traditional medicine and shelter. A case study was conducted in Japan to record the abandonment and degradation of forests and studied the benefits of saving them. “Their report put the total value of the ability to absorb carbon dioxide; use of wood instead of fossil fuels; reduction of erosion and flooding; regulation of and cleaner rivers, and health and recreation, at ¥70 trillion (£535bn) every year”(Jowit 2010). Disadvantages of zero-deforestation policy include: loss of jobs that are designated in forests (lumbermen) and possible economic disadvantages for suppliers in emerging markets and developing countries/
Two case studies that are directly related to the effects and solutions to loss of biodiversity were conducted in Nigeria and Paraguay. In the more recent years, the issue of biodiversity loss has been deeply researched and studied in attempts to slow the decline. A deforestation study that was conducted in Southwestern Nigeria aimed to examine the occurrence of deforestation, to assess the rates of deforestation and compare the depletion over time, and to explain the factors that are responsible for deforestation and what effects it has on forest biodiversity. This region is well known for its dense forest resources and fertile soils but due to rapid population growth and increased farming, much of this land has been turned into farmland to keep up with the growing population. Zero Deforestation policy was implemented in 2004 in Paraguay and this case study proved that the deforestation rates have dropped dramatically. This law made it illegal to clear any forested land in eastern Paraguay. Due to its success, the law has been extended twice and the government has now committed to cut net carbon emissions from changes in land use to zero by 2020.
Although many people are still unaware and uneducated on the threats that are posed to the environment that lead to biodiversity, it has become much more talked about which has prompted many people to take action to try and resolve these issues. There will always be challenges and obstacles that one must face in taking these issue head on, but like any long term goal, it can be achieved by taking the necessary steps in order to do so that will eventually lead to a more prosperous and properly functioning ecosystem.

...Affects on Biodiversity Biodiversity is defined as “The range of variation found among microorganisms, plants, fungi, and animals. Also the richness of species of living organisms” (ESA). It the diversity among ecosystems, species and genetics. Biodiversity provides organisms,including humans; food, homes, and nutrients for healthy living. It provides clean air, water and nutrient rich soil. Biodiversity allows for animals to adapt to their changing environments. There are many different human activities that have had a negative impact on biodiversity globally. Fossil fuels is one the major factors influencing the changes in our ecosystems. “Many of the factors leading to the accelerating loss of biodiversity are linked to the increasing use of energy by society” (Ash, 2007) The emissions of fossil fuels is a direct link to global warming. The climate changes have an effect on habitats, reproduction, water temperatures, and genes. It also has effects on economies and health policies. Pesticides is another element that has an negative impact on biodiversity. Pesticides can influence the nutrients in soil, and health of animals and water supplies. A group of chemicals often used for pesticides, endocrine disrupters, have many corrupting effects on animals, and habitats. “Endocrine disrupters are especially dangerous to wildlife - not only do they cause instability and increased mortality in the population, but their long-term effects severely dampen their......

...Biodiversity Paper Biology as a science concerned with living organisms, said organism’s function, origin, structure, and distribution is defined through numerous subdivisions and branches. Conservation biology is a branch, which deals with certain factors threatening biodiversity as well as the preservation of genetic and biologic diversity of animal and plant species. Threatened, endangered, and extinct species are only some factors that may influence biodiversity. Any given species has to meet a certain criteria to suit the previously named terms. Conservation biologists are concerned with numerous species because of said species’ influence on the interrelation within their ecosystems, and the interruption of such ecosystem when the numbers of a certain species are drastically decreasing. Conservation biology is concerned with the maintenance of species, their genetic variation, ecosystems, and communities within such ecosystems. Biodiversity includes “The variety of life and its processes, including the variety of living organisms, the genetic difference among them, and the communities and ecosystem in which they occur” (U.S. Fish & Wildlife Service, 2004, p. 1). Even though the term “species” is complex, and some definitions may differ slightly from others “A species is often defined as a group of individuals that actually or potentially interbreed in nature” (Berkley University, n.d., p. 1). Therefore, a species is defined as the greatest gene pool that can...

...BIODIVERSITY Biodiversity is the degree of variation of life. This can refer to genetic variation, species variation, or ecosystem variation within an area, biome, or planet. Terrestrial biodiversity tends to be highest at low latitudes near the equator, which seems to be the result of the warm climate and high primary productivity. Marine biodiversity tends to be highest along coasts in the Western Pacific, where sea surface temperature is highest and in mid-latitudinal band in all oceans. Biodiversity generally tends to cluster in hotspots, and has been increasing through time but will be likely to slow in the future. Rapid environmental changes typically cause mass extinctions. One estimate is that less than 1-3% of the species that have existed on Earth are extinct. Since life began on Earth, five major mass extinctions and several minor events have led to large and sudden drops in biodiversity. The Phanerozoic eon (the last 540 million years) marked a rapid growth in biodiversity via the Cambrian explosion—a period during which the majority of multi-cellular phyla first appeared. The next 400 million years included repeated, massive biodiversity losses classified as mass extinction events. The Carboniferous, rainforest collapse led to a great loss of plant and animal life. The Permian–Triassic extinction event, 251 million years ago, was the worst; vertebrate recovery took 30 million years. The most recent, the Cretaceous–Paleogene extinction event, occurred 65......

...Yamir Ortiz March 26, 2014 Dr. Palestis Biodiversity Discussion Impacts of Biodiversity Loss on Ocean Ecosystem Services “Impacts of Biodiversity Loss on Ocean Ecosystem Services” by Worm et al. 2006, was an interesting paper to read. The article talks about the dangers and the effects humans are having on the marine ecosystems. It also touches on the importance and benefits that diversity has. As we all know, the marine ecosystems of the world have the ability to provide us with an array of different resources, most importantly, food. Because of us, through exploitation, pollution, and habitat destruction there are changes occurring within the biodiversity of the marine ecosystems. There have been observations within estuaries, coral reefs, and coastal and oceanic fishing communities that there is a rapid decrease in population, species, and entire functional groups. Due to diversity between producers and consumers, species are able to overcome/survive more such atrocities by allowing them to be stable and have higher efficiency of resources. When looking at coastal ecosystems, experiments conducted reveled a fast decline in native species since industrialization increased, causing pollution within waters. Systems that contained more diverse and species rich environments showed to be more stable causing them to have lower rates of collapse and extinction over time. When looking at the larger marine ecosystem there has been a larger collapse in the areas that......

...Using Figure 2, explain why a spectrum of strategies is used to help conserve biodiversity Biodiversity is a key resource, which provides a range of valuable goods and critical services to human populations. Biodiversity results from natural physical processes, and as such has distinct geographical patterns. Biodiversity is under threat in several ways; habitat destruction, over-exploitation of natural resources, pollution, introduction of alien species, climate change and increasing demands on nature from rising human populations Sustainable management with use of ecosystem resources is used in-order to help conserve biodiversity because it is trying to allow people to get what they need out of an area but also try and conserve it. A way in which this is usually managed is by zoning, which is where they create and area where humans are not allowed to touch, the area is usually one which has high biodiversity. The reason as to why people tend to damage areas is for agricultural reasons and also logging. This will reduce the threat on habitat destruction and exploitation of natural resources. Protected areas with managed access, e.g. national parks in Kenya is used to help conserve biodiversity because these area tend to be under threat from humans. This is because of the landscape and the wildlife which are in the area and also due to the increasing demand from humans. If the area is protected and managed it means that people are able to still visit the wildlife but in a......

...Biodiversity a.Biodiversity- is the degree of variation of life. It is a measure of the variety of organisms present in different ecosystems. This can refer to genetic variation, ecosystem variation, or species variation (number of species) within an area, biome, or planet. Terrestrial biodiversity tends to be highest near the equator, which seems to be the result of the warm climate and high primary productivity. Biodiversity is not distributed evenly on Earth. It is the richest in the tropics. Marine biodiversity tends to be highest along coasts in the Western Pacific, where sea surface temperature is highest and in the mid-latitudinal band in all oceans. There are latitudinal gradients in species diversity. Biodiversity generally tends to cluster in hotspots and has been increasing through time but will be likely to slow in the future. b. bioinformatics-is an interdisciplinary field that develops methods and software tools for understanding biological data.

Every living organism has a purpose in order to keep the balance of biodiversity. In order for there to be “biological diversity, these items are organized at many levels, ranging from complete ecosystems to the chemical structures that are the molecular basis of heredity” (1987). Not always in a friendly environmental manner, Human actions has played a big key role in the changing of the environment. A nonproductive planet would be result, if we did not have an abundance of species and ecosystems. All living organisms rely on one another to survive and thrive. Biodiversity is the total of species living together in an area, a community, or the entire planet. Genetic diversity, habitat diversity, and species diversity are three different concepts can be defined as Biodiversity. The same species in different populations found with patterns of variations and a bundle of different genes located in one species is known as genetic diversity. Within a specified area, the number of different habitats is habitat diversity. When checking for species diversity there are three qualities that you should look for species dominance, species evenness, and species richness. The most abundant species measured is species dominance. The......

...levels of biodiversity (15) Both physical and human factors influence biodiversity. On a global scale, climatic and soil fertility influences affect levels of biodiversity, although often human factors influence biodiversity at a local scale and increasingly globally. Biomes and large scale ecosystems such as coral reefs are influenced by limiting factors such as salinity of water which should remain constant, temperatures between 25 and 29 degrees C and adequate sunlight so turbidity level are low. The Great Barrier reef is home to 5,000 species of molluscs, 1,800 species of fish, 125 species of sharks. The age and size of an ecosystem is important in supporting high levels of biodiversity. On the island of Borneo, a biodiversity hotspot, has a number of endemic species and sustains high levels of biodiversity as there is range of altitudes supporting different niches and the size of the area supports many predators. At the local scale, threats from human activity such as deforestation can severely influence biodiversity levels. In Borneo, pristine rainforest was removed for timber and mineral exploitation and the result was a wasteland of yellow grass with low biodiversity. However, human factors can also benefit biodiversity as replanting of native species fertilized by cow urine has subsequently increased biodiversity in the area and the area has been designated an Orang Utang protected area.

Looking at this picture you see a dog and a orangutan, but what you don’t realize is that they are similar in more towards their classifications. The classification for a dog includes kingdom animalia, phylum chordata, class mammalia, order carnivore, family canidae, genus canis, and species canis lupus. While the orangutan classification includes, kingdom animalia, phylum chordate, class mammalia, order primates, family hominidae, genus pongo, and species pongo pygamaeus. We can compare and contrast the different animals that belong to some of the same classifications. Even though they are apart of the same kingdom, phylum, and class they do not seem to be apart to have any similarities. Biodiversity has to the chance to prove that everything could be similar.

...Biodiversity is commonly referred to as “The variety of life on Earth” when talking about the Earth’s biological diversity. It includes the numerous and vast variety of species of plants, animals, and microorganisms, the diversity of genes in these species, and the different ecosystems on the planet such as deserts, rainforests and coral reefs. They are all part of a biologically diverse Earth. The role of biodiversity is important in the way ecosystems function and in the many services they provide. Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. Just think a larger number of plant species means a greater variety of crops, a greater species diversity ensures natural sustainability for all life forms, not to mention healthy ecosystems can better withstand and recover from a variety of disasters. It’s a big deal that we as humans should preserve the diversity of wildlife. By nature a healthy biodiversity provides numerous services for everybody. Provisioning resources, which are the products obtained from ecosystems that have a diversity includes food. The growth of crops, spices, and meats and vegetables. Medicine which is naturally grown in the wild that is of use to humans and wild animals alike, as well as raw material such as lumber, and fertilizer. For example, Waste eaters like the dung beetle help to turn animal waste into organic material that can be reused by plants, which will further......

...Bethany Thomas 07 February 2016 Biodiversity Biodiversity is defined as the variety of life at all levels. This is especially important to consider when dealing with conservation. “Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play.” (Shah) This speaks volumes to the fact that everything is interconnected and all of life depends on each other to survive. Whether it is the ability of an ecosystem to recover from a disaster or diverse species creating a natural balance, biodiversity is at the root of almost all cultures and conservation practices. In the film, Regeneration Principle: Biomass, the main focus is the use of plants as a source of clean renewable fuel for energy. The impact of this would be for the most part positive, but would all depend on how it was managed. These plants would need to be grown and harvested in a way that would not disturb the natural balance of the local ecosystem. If it is naturally occurring, you must ensure that it is harvested at a sustainable rate. The biggest impact would be the ability to cut our dependence on fossil fuels and shift to a resource that can be renewed and replaced at a much faster rate. The use of the otherwise inedible, useless nuts is a great example of a resource that can be utilized and renewed if used properly. I do not feel that the use of corn to make ethanol is not worth the impact to biodiversity. The amount of land and the......

Under the mammal category, I chose to research Capuchin monkeys and ferrets. Capuchin monkeys are small, weighing between 3 to 9 pounds with varying fur, but commonly colored dark brown with cream or light tan coloring around their face, neck and shoulders. Capuchin monkeys are classified under the primates’ order because, for one, they carry the adaptation for climbing trees and walking on two or four limbs. Capuchin monkeys are in the same order as lemurs and mountain gorillas. Domestic ferrets are long, slender bodied animals with brown, black, white or mixed colored fur. The average length of a ferret is 20 inches which includes a 2 inch tail and weighs between 1.5 and 4 pounds. Ferrets are a part of the carnivore order and the reason they are classified as such is because they are meat-eating animals. They are joined in this order with animals such as polecats and weasels. One characteristic Capuchin monkeys and ferrets share is their abilities to adapt to living in different environments such as captivity. A second characteristic is that both types of animals can be considered a nuisance to......

...The Problem: Seeing the video on Declining Fish Stock VLR, expose the challenges between fishermen and environmental concerns. This video shows how fishing fleets have depleted the oceans of almost 90% of its big fish; therefore, claiming the ocean is not as resilient as it once was. The majority of the largest fish have already been pulled from the oceans, leaving only 10% of its remaining fish for Commercial fishermen to make a living. Most fishing fleets today are two to three times larger than they need to be to catch large fish and other seafood. Because of commercial fishing many fish are not able to reproduce fast enough to maintain their species. A manageable and sustainable plan will need to be implemented to avert these fish from completely disappearing from the oceans. The plan will need to be a partnership between fishermen, communities, governments, and environmentalists. Overfishing has considerably exhausted certain species in the ocean and they are now extinct. To think we can continue to hunt fish, with no major regulations or limits to feed billions of people is extreme. Since biodiversity do continue to decline, the aquatic surroundings will not be able to maintain our human consumption for seafood. This situation can still be reversible by working together with some basic ground rules. Because of the current conditions and the magnitude of the problem, replenishing the ocean may take a decade or perhaps even centuries to restore....

...the form of faeces, and also digest cellulose using cellulase from their gut and the enzymes from the environmental microbes (C. T. Ivey, N. DeSilva, 2000). This is because the large surface area of the dead matter causes the decomposition process to be slow, and the cellulose cell wall of the plant impedes the entry of microbes (C. T. Ivey, N. DeSilva, 2000). This knowledge made me appreciate the beneficial roles of termites besides condemning them for their destructive capability. This also caused me to realize that some organisms, despite being detrimental to the human society, can contribute to the ecosystem in a positive way. Another insight I have gained from this practical was how human interference in the past can affect the biodiversity of the forest in the present. The forest that occupies Kent Ridge is a secondary forest called Adinandra belukar. “Belukar” means secondary forest and “Adinandra” refers to the dominant species, Tiup Tiup (Adinandra dumosa), that can be found in the forest. The forest has a lower diversity as compared to other forest. This is attributed to its highly acidic and nutrient-poor soil, which was caused by action of man in the past. The area was initially occupied by Gambir (Uncaria gambir) plantation, before it later made way for Rubber (Hevea brasiliensis) plantation (Tan H.T.W. et al, 2003). As the growth of Gambir requires certain nutrients, it depleted these nutrients in the soil and led to a nutrient-poor soil, as seen today. The......
