How much do you cherish and love the Earth?
In the past half billion years, five great extinctions have transformed life on Earth, whether brought about by a catastrophic meteor impact that killed off the dinosaurs or prolonged periods of intense volcanic activity, which wiped out as much as 97 percent of all species. Now, say scientists, Earth may be experiencing a sixth wave of mass extinction. But this time, humans are the cause. Forty-one percent of amphibians, 26 percent of mammals, and 13 percent of birds face the threat of extinction, according to an analysis conducted by the journal Nature. Over hunting, habitat destruction, and climate change are propelling the die-offs, as well as the spread of invasive species and disease.
We want to reduce the serious environmental problems.
