Resources problem on the Earth
Natural resources
The natural on the earth resources is limited.For example, the formation of mineral resources were not easy.It took millions of years, and even a few billion years to become them.The Earth is selfless, and it generously provided them to us.However, if we do not control the exploitation, they will be exghausted quickly.
Resourses problem.
Can we move to the other planet to live when the resources are exghausted?
Positions:
We can go to the other planet. (1)
we can't go to the other one. (4)
- we can't go to the other one.
I don't not think we can. First of all, according to our current technology, we can not fly to other planets. On the other hand, in the universe, we hasn't found the second "Earth" . Furthermore,if we want to fly to the other space ,we need a lot of resources, financial and material resources. Therefore,in my opinion we can not.

We know there is plenty of water on the earth.So far,water is the basis for us to live.The human hasn't found water on the other planets yet.Because of the water,we can't move to the other planet to live.
