Biodiversity Loss And Loss Of Species Essay

The number of wild animals on Earth has halved in the past 40 years . Creatures across the land, rivers, and the seas are destroyed as humans killed them for food in unsuitable numbers, while polluting or destroying their habitats.

“ (Gerken) . Humans are the main reason of deforestation and well this another reason that animals are going extinct. We’re killing their homes for our needs, and instead we should find an alternate. Also, according to the World Wildlife Fund, “Habitat loss is probably the greatest threat to the variety of life on this planet today. It is identified as a main threat to 85% of all species” (Latham).

Forests have been cut, crops planted, pastures seeded, and urban areas paved. One of the most troubling consequences of human modification of ecosystems is an ongoing loss of species and therefore a loss of biodiversity around the world. The current extinctions have a human cause: habitat loss (such as clearing of tropical rainforests); the introduction of invasive species; unregulated hunting and fishing; and pollution of water, air, and

As we continue to grow and have a greater impact on the Earth’s systems, it is essential that we address our role and relationship with nature. The separation of humans from nature encourages environmentally irresponsible behavior because it allows us to take on the conqueror role, giving us the ability to manipulate the landscape with the duty to provide and proliferate. Throughout human history, we have made advancements in technology and agriculture, resulting in the imbalance and overuse of land. The ability of humans to manipulate the landscape and recognize the consequences of doing so makes us an invasive species. Our dependency on Earth’s resources and services put us at competition with the environment. In order to understand our role

Throughout evolution, many species have come and gone. What causes a species to become extinct and what can the human race due to prevent it? Many species’ population decline has been linked to human causation. An endangered species is defined as “plant and animal species that are at risk for extinction” (Funk). Endangered species can be placed into two more specific categorizes. Threatened species are species at risk for endangerment, while endangered species are at risk for extinction. Despite the fact that many people believe extinction is a major issue, the Funk and Wagnall’s New World Encyclopedia states that, “extinction is actually a normal process in the course of evolution” (Funk). Over time, numerous species have become extinct, usually as a result of climate changes, inability to adapt, or predation. Another major cause of endangerment is the human population. Pollution, global warming, and hunting is all causing a decline in the population of numerous species. While the encyclopedia is entirely fact based, many authors have worked to sensitize people to threatened species. For example, renowned author Sharon Begley, has written numerous articles to inform people of the importance of many species that are often overlooked.

As we lose more and more habitats, it could create a domino effect causing many other complications in the world's ecosystem.

re devastation and harm that may not be able to be undone if our society fails to take the necessary action to sustain life of all ecosystems.

Did you know that there are 13 species of animals who we may have to say goodbye to in 2015, or an estimated 2.2 billion tons of waste is yearly dumped into oceans? There is no need to research the litany of environmental changes; news such as global warming, air pollution, or resource scarcity that choke environmental problems to appear daily on TV screens and in newspapers. Even with these particularly cautions, many of us are still facing environmental catastrophes with overly optimistic attitudes, ignoring how serious the matter is. This form of the unrealistic expectation is similar to the blind development in our technological society that engenders a series of environmental and economic problems. Paul Ehrlich, [1] a Stanford University

Edward O. Wilson suggests that humanity should pay attention to our environment. He was concerned about the large extinction of species within a single human generation. He has two reasons as to why we should pay attention to our diverse biosystem, which includes plants and animals. First, some of the species in our environment, large or small can have an economic value and can be used as a source of food or medicine in the future. He put an emphasis on people being ignorant by destroying on what might be a possible cure for cancer or any other disease. The second reason is the annihilation of a vast number of species might lead to the collapse of our ecosystem. For instance, the widespread loss of trees from brush fire or destruction of islands

Since the Industrial Revolution we have practiced deforestation, burned fossil fuels, and as a result we have disrupted stable ecosystems. Advances in medicine and technology have given humans the ability to increase their carrying capacity. While increasing our carrying capacity we have also decreased biodiversity around the world. We have introduced different species in new environments to help ourselves

The main cause of the loss of biodiversity can be attributed to the influence of human beings on the world's ecosystem

We as humans are causing an excessive amount of habitat destruction due to industrialization and creation of infrastructures. We’ve polluted the air with smokes and fumes, torn down forests to build shopping malls and highways, and degraded and overused the soil for our own profit. We are so concerned with furthering our industries and businesses that we forget that the earth is the main source of it all. We also fail to replace what we use. Because we continue to hurt and destroy mother earth, she will eventually become a pile of nothingness.

There are a myriad of effects that humans have on the planet. From the great structures erected at Giza and the monuments of ingenuity at the Eiffel Tower and Empire state building, mankind has made his presence known. This expansion, or progress as it is called, has sadly had a devastating effect on the surrounding ecosystems.

Franck and Brownstone define biological diversity as 'the variety and variability of living organisms and the biological communities in which they live' (36). Decades of progress in both the scientific and political arenas have advanced environmental legislation to protect biodiversity at not only the ecosystem level, but for specific species and genetic material as well. Research has shown the importance of every organism and their role in the global ecosystem, and legislation has gradually matured to protect not only species which may become endangered, but the habitats they need to survive as well. Growing consciousness surrounding environmental issues has enabled these protections to be

The health of the earth degrades with the destructive activity of human beings. A recent study by a group of scientists looked at twenty four different services that the earth’s ecosystems provide for humans, ecosystem services, and found that fifteen of them are in need of desperate help (Gazette 31 March 2005). These services are vital to the survival of both human and nonhuman life and include filtering water and providing nutrient rich soils and ocean waters. Many of the members of these various ecosystems are also decreasing in numbers. In a British survey of bird populations found that in the 200 birds of Britain tracked there was about a 54% population decrease between the 1968-1971 tacking period and the 1988-1991 tacking period. In two other surveys of 254 native plant species from the same area there was a decrease of about 28% during the past 40 years. Humans are pushing the sixth mass extinction (Gazette March 19, 2004).
