Have we been good to the earth over the years?

I do believe we have done earth wrong. Look at all the animals that are extinct. I am talking about the animals that man has played a part in them becoming extinct. Then we were for a long time just cutting trees down and not replaceing them. Nature has a way of keeping the balance of nature equal but man has put his hand into things and knocked Natures balance off. Now we are trying to fix things and if we had left them alone to begin with than the earth would be fine.

I must say that we responsable for the consequences so...no we weren't good with planet earth. We made industries are polluting and yet we are using and buying their products. Animal have been tortured and they do feel scared when getting killed but we still eat them. However, we are already depending on those things. I think eating is part oe ecology. Some carnivor animals feed on other animals in order to survive. SO I guess, we are equal to others for this point. However, we destroys the environmet. We know our mistakes and we try to fix it back step by step. We were bad but it's not human's fault because they have been ignorant. Back in the days, we kept on polluting without knowing the earth was suffering. It is only when the damages have been shown that we are trying to repair our mistakes. The answer is obvious but I know the people in the future and us will be more caring for earth.

Surely we have done wrongly to the earth and all animals on it. Not only have we been cruel to the animals by hunting them for food and pleasure, but we have destoyed their habitats which pronouced their doom. Are there any possibility that human can change its behavior? I don't think there are. We have been even cruel to our own species. Think of the all the wars we have fought. Animals won't get any mercy from us if by our brothers and sisters can not ask mercy from us. Our earth is doomed.
