Biological Diversity

In contrast to the upheaval of animals in a development area, humans also make efforts to preserve biodiversity and forests by creating wild life

The scale and pace of change is dramatic; for example, the extinction of species is occurring at around 100-fold pre-human rates4. The population sizes of vertebrate species have, on average, declined by half over the last 45 years5. More than 2.3 million km2 of primary forest has been felled since 20006. About

Animals in forests are going extinct due to a very disastrous cause. For example, there is a specific tiger race that only has fewer than four hundred left in the world who live in these forests of which are being torn down and burned every single day. With the rates of deforestation rising, these tigers will be gone altogether in a matter of a couple of years. Not only will the animals be in danger, our environment will be, too. The area where the trees have been will dry out due to the water cycle that the trees are involved in helping with being less effective.

Long-term survival of a species depends on its ability to adapt to changing environmental conditions (Murphy, 1994). Genetic diversity within a species, which has taken 3.5 billion years to evolve, makes adaptations to these changing environments possible. Unfortunately, the rate of extinction of genetically diverse organisms is rapidly increasing, thus reducing this needed biodiversity, largely due to the human impacts of development and expansion. What was an average of one extinction per year before is now one extinction per hour and extinct species numbers are expected to reach approximately one million by the year 2000 (WWW site, Bio 65). As a result governmental and societal action must

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

Biodiversity loss threatens to disrupt the function of ecosystems, with the potential of consequences for humans as well. Often this loss is measured by species extinction rates, but considerations should be made to include population diversity with measures including changes in size, number, distribution and genetic composition of population and potential implications those changes may have (Luck et al., 2003). Avise (2004) goes as far as to say biodiversity is genetic

To begin with, habitats are shrinking. The article shrinking habitats from expert space states, “ A study shows that 70 percent of forest grounds are within a half-mile from the forest edge which is causing harmful effects”. These harmful effects are animals dying due to cars and getting lost from where their habitats are. These effects are boosting the rate of extinction.Also, in

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

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

Because of this it is identified as a main threat to 85% of all species described in the IUCN's Red List (those species officially classified as "Threatened" or "Endangered"). The world's forests, swamps, plains, lakes, and other habitats continue to disappear as they are harvested for human consumption and cleared to make way for agriculture, housing, roads, pipelines and the other hallmarks of industrial development. 80% of the animals live in the rainforests and if deforestation keeps going on then then might even get

Background Information- In this lab we explored how biodiversity can be loss in an ecosystem due to random events and invasive species. To begin with, “Biodiversity is the varieties of organisms and complex ecological relationships that give the biosphere its unique, productive characteristics.”(Cunningham 227) It is usually recognized by species. Biodiversity is important because certain

Species are disappearing at a rate of 100 times higher than if humans weren´t around. They get used to their environment, but we destroy them by cutting trees to make paper or built buildings, we liberate so much CO2 during fossil fuel burning, which affects the climate in which they

2. Climate change would have an impact on all members of the food chain. There would be lots of habitat loss and animals would have to try to move to a different location for food and then the animals that hunted those animals would have to find a new food source and some plants would be affected and die off because they cannot move. This would affect the diversity because then the populations would be

The article focuses on the habitat loss due to deforestation. The author talks about the different purpose of deforestation such as agriculture, forestry, or water projects that endangers the species that live in the area. The article is based on information taken from World Wildlife Fund, IUCN, and Red List. The information that the author provides is important and useful to the topic of deforestation. Overall, the article is well written and well researched.

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
