			Lessons for today in ancient mass extinctions - May 2012 If you follow environmental news at all, you'll be familiar with the most common cause of extinction in the world today: habitat loss. Habitat destruction threatens the survival of some the world's most charismatic organisms — animals like the giant panda, the Sumatran tiger, and the Asian elephant. Humans have encroached on the wilderness in order to farm, mine, log, and build, and in the process, we've pushed the natural inhabitants of those areas into smaller and smaller refuges. Making matters worse, global climate change caused by our production of greenhouse gases is altering the environments within those refuges, forcing species to contend with new challenges. While these might seem like entirely modern problems, recent research indicates that's not the case — and that current levels of habitat loss and climate change could have devastating consequences ...
