that said, i don't feel pessimistic that we are going to run out of resources: we are becoming more efficient at producing food faster than the rate at which population is increasing. there is, however, a risk that we will wreck the environment so effectively that the world will no longer be an attractive place to live. that really would be a dismal outcome, to reach world population equilibrium only to find we'd destroyed the natural environment in the process.
nowadays,population as well as environment has become a very important problem.
with the development of china ,the population is growing faster and faster,though,chinese government has put forward strageties, such as ,one child policy.but at the same time ,the increase has slown down,which is to our relief.
as for the environment,the biggest problem is that people do damage to it and seldome do they protect.so,we would like to say,if they still don·t stop those silly mistakes made to destroy the environment,one day ,human beings will be the last creature in the world. protect the environment!our earth is our mother for all of us.
