Habitat alteration is the main factor in species endangerment throughout the world (Plant).The main reason birds are endangered is because of habitat loss. (Sayre 10). Wetlands filling and draining, agricultural expansion, and residential housing development are all examples of habitat alteration and destruction (Plant). When deciding whether a species should be added to the endangered species list the factors to be considered are: Has a large percentage of the species habitat been degraded or destroyed? Has the species been over-consumed by commercial, recreational, scientific or educational uses?
What changes happening in Madagascar are posing challenges for lemurs? Give details about the sources, time scale, and types of change. The challenges for the lemurs in Madagascar are that the vegetation is being destroyed by humans. According to the video, the timescale for this destruction is a lot less than an evolutionary timescale of destruction. One of the changes that would pose this threat to the lemurs is that their food supply is being demolished so they could die off because of starvation.
Wasting Away Chronic Wasting Disease (CWD) is slowly eating away at much of the population of white-tail deer, moose, and elk in North America. CWD deteriorates the brain of an animal. It is infecting many of the deer in the Midwest and spreading all over the nation with a rapid pace. This horrific disease has been found as far north as Wisconsin and all the way down to New Mexico. There are many things that cause CWD, and it needs to be stopped before our white-tail deer population is considerably damaged.
They lose their habitat and forced to move to new location; besides, many cannot survive the deforestation that destroys their homes. It is undeniable that deforestation itself has extreme effect on Global warming and hurts the air. Global warming means that air and ocean temperature is increasing. Greenhouse gases exist primarily because of human activity. Unfortunately, humans are the most polluting species on the planet.
Will humans be the ultimate downfall, and eventually cause the extinction of the snow leopard? What can we do to protect these magnificent creatures? Like many other top of the food chain predators, the snow leopard populations are in rapid decline. This is mainly because farmers and their livestock share much of the same habitat as the snow leopards. The snow leopard’s diet includes wild sheep, goats, and other large mammals of comparable size, but is not limited to these larger animals.
There are many different reasons why extinction happens, some of these cause are natural but the majority of them are due to human activity such as deforestation and an increased amount of fossil fuels being used which then leads to global warming. Extinction has increased 100,000 times more than before humans were on earth. There currently is a mass extinction of species since the extinction of the dinosaurs 65 million years ago, some of the main causes of this are habitat destruction, invasive animals, population growth, pollution and over exploitation. Biodiversity is the variety of plants and animal life in the world or in a particular habitat which are affected negatively due to some activities that humans are causing such as climate change. My first piece of evidence in favour of human activity leading to extinction is ‘humans are driving animals to extinction faster than they can evolve ‘written by Juliette Jowit, (on Sunday the 7th of March 2010), the guardian newspaper, 15/01/15.
English 101 October 2, 2013 Deforestation and the Red Panda Deforestation is the cutting down of a forest. Forests are cut down for many reasons, including logging, farming, and housing. Deforestation can have many harmful effects, including loss of habitat for many different plants and animal species. Because of deforestation, many plant and animal species (some known and unknown to us) are lost due to the loss of habitat. About 50 thousand species of animals and plants disappear in result of deforestation every year.
