As human populations grow, pollution soils the environment and infrastructure develops, our natural habitat suffers. This may sound familiar, but scientists sent a resounding message today when they announced in a comprehensive five-year global wildlife review that these human-based causes and more are threatening one in four of the world's 5,487 known mammal species and have put 188 species in the critically endangered category. The study, which drew on the expertise of 1,700 researchers from 130 countries and was led by the International Union for the Conservation of Nature's Red List of Threatened Species, also revealed that one in three marine mammals faced extinction.
Although conservation efforts have been ramped up—five percent of formerly endangered species are facing recovery—the report cautions that better results are needed and that humans, whether directly or not, are to blame for many of the ills facing mammals. For instance, 78 percent of marine mammals are now endangered due solely to accidental deaths (like by being caught in fishing nets not meant for them or being hit by ships) and 40 percent of mammals are threatened because of damages to their habitat. Agricultural expansion, rapid economic development and sharp population growth, are among some the main factors behind why Asia has the most endangered species at 79 percent. In the meanwhile, hunting puts approximately 17 percent of mammals groups at risk.
The facts are bleak, and the damage in some cases may be irreversible, but it's perhaps another telling reminder that we need to take action on a global scale before it's too late.
I feel living in fiction sometimes,just acompanying with myself.Now human may have such idea to live by themselves.
Its sad to think of the huge impact humans have on the world's ecosystem, and how its almost all negative. Yes, there are individuals that try to make a diference, but its still getting worse. I can't stand thinking of how much damage industrialized nations do to the world's ecosystem, and then how most of the world hasn't began to industrialize yet.... imagine what the ecosystem is in for in the future.
I think we need to do something, and stop this from happening. Global Warming is the cause of this-or is it? Just think, humans have caused Global warming and we aren't doing anything to help or to stop it. Its our fault the animals are becoming endangered/extinct, and we need to stop it!
Just think, humans have caused Global warming and we aren't doing anything to help or to stop it. Its our fault....?

The world will experience global cooling this year, according a leading climate scientist.
The head of the World Meteorological Organisation said La Nina - the weather phenomenon which is cooling the Pacific - is likely to trigger a small drop in average global temperatures compared with last year.
The prediction - which follows a bitterly cold winter in China and the Arctic - is prompting some sceptics to question the theory of climate change.
