We need to help conserve plants and animals.
When we kill animals we get food, and yes I understand that we have to eat meat to have a healthy diet, but we are taking too much.
If we only took what we needed and used all the animals parts then there would be enough food for everyone.
When you don't have trees you don't have oxygen and without oxygen we as humans can't survive.
If you don't like animals why are you here?
Thank you for your time to learn about the earth. :)
