Some people view the rapid population growth in less-developed nations as the primary cause of environmental problems. Others see the high rate of resource use per person in more-developed countries as
the problem. Which factor do you think is more significant? Why?

In my opinion, I think the high rate of resource use per person in more-developed countries is the problem because we are obviously over using them, especially in countries who have lots of people. We shouldn't take advantage of it and use our resources wisely because you never know when something certain is going to run out.

For example, paper is an over-used resource because sometimes people draw on blank pieces of paper and if they mess up or don't like what they wrote, they crumple it up and throw it away. In conclusion, we need to make sure we use our resources to the best of our advantage and not waste them.

sorry if that's too long i tried my best xD
