Blog #5 There have been 5 major extinction events throughout history, are humans impacting the 6th? Why or why not?

l think human definitely have a big impact on animals or plants' extinction.First,we take almost all the land or living environment away from these poor living things,They just have a little place to reproduce and survive.All the orignal natural landscape become tall buildings and factories.Animals won't be happy about that.Second,today's world occurs too much pollution.For example:electronic and oil factories will release enromous air pollution which can be fatal to animals.The water pollution also is a very serious problem.You can't count how many fish died in China's dirty river or canal.Third,people kill some value species for money as well,it's very ruleless and selfish.Most endangered animals are face to extinct because human's greedy traits.ln briefly,if human don't stop this kind of harmful action,there will have a high risk to impact a sixth extinction.
