Supposedly, there has been five destructive events that have killed off almost all animal life on earth. Yes, I agree that mass extinctions have killed off life on earth, but what most do not understand or see is that us people cause some of this.It all started from asteroids to volcanoes. We cannot help natural disasters, but we could find other ways to help prevent pollution and global warming that changes the climate for certain species. There is some things in this article that I do not agree with like “We use more than half of the planet’s unfrozen land for the cities and logging or food” (Scientific American 1). So do they expect us to not eat or build places we need? We cannot survive ourselves without food and a place to live. I do not believe these natural habitats has killed off animal and plant life. They say that humans have caused nearly 1,000 species to go extinct, but my question is what have we done to cause that many to go extinct? Since back in the 1500’s we have supposedly killed off 322 types of animals, to some people that might seem like a lot but really it is not. If you look at it as of how many different types of species there was in each group of the animals, then I guess it might seem like a good bit. I do agree and believe that many of animals are endangered everyday, it has been happening for years but I don’t think it has happened as quick as scientist say it has. Recently, the only freshwater mammal left on earth, a dolphin went extinct in China. How did that happen, without people polluting the water it lived in? They say a sixth mass extinction is starting to occur, but I do believe people today can help avoid it, I think that we are starting to help save life on earth more and more everyday as much as we can.
