Balance of Nature

The balance of nature is a crazy system. One little thing off setting it could kill everything off. The balance of nature works like this, insects eat plants to stay alive. Animals then eat the insects to stay alive and healthy. Then the humans eat the animals for food. Land gives us nutrients for food and a place to keep our feet. What keeps this all in balance is a never ending chain. As long as this chain doesn't stop the world keeps moving and working. If the chain does stop then we are all screwed.
The world is still in balance today but is slowly being ruined. We will probably never live to see the day it stops being in balance and the chain ends, but our kids kids kids may be unfortunate enough to see that day. As for whats knocking out of balance it's a simple answer. Humans. We are the cause to all problems! In the balance of nature we are the part that ruins it. We pollute the air with so much stuff that we have actually put a whole in our ozone layer. We are slowly causing global warming. We destroy the trees that give us the air we need to breath for our wants not our needs. There are many different options we can use to make paper but we decide to cut down trees instead. When we ripp down forest we kill animals and take their homes from them. So many animals are becoming extinct because of us. What happens when the kill off an animal that was apart of the food chain. Then they die and what ate them eventually dies then so on and so on. We pollute our waters by dumping garbage in them. We spill oil in the water we drink. It is like we dont care about the world we live in. The world to humans is like a house to a family. Instead of keeping a clean safe house, we trash it and leave it and eventually it will be unsafe to live in.
