An interesting take on a very real problem. With all due respect to those who believe otherwise, there is a limit to how many people the Earth can support. What is that number? 10 billion? 30 billion? 100 billion? My guess is you could line up twenty people who study such things and all would give a different number with research and evidence to back it up. Even though we may not know the exact number that will be the proverbial “straw that breaks the camel’s back,” basic common sense says that as population increases, more strain is put on that population’s habitat as more resources are consumed.
It’s a well known fact that humans have a greater impact on the Earth than any other species currently alive and as our population grows, we’ll have to do one of two things: manage our resources better or manage our growth better.
