An environmental catastrophe can come from deaths(bodies) , ways of environmental destruction and too much population. Since the population is getting bigger every year, a lot more resources are being used which means we will eventually run out of resources. We would be running out of food, water, anything we would need to live. If so would happen, the world would be coming to really rough times. How I would deal with this problem is try to multiply these resources. Try to make more and more food, try to save water and not waste it into unnecessary places and usages. There wouldn’t really be much to do other then try to make more of what would be essential for us to survive and try to have anything needed.
