Weblog Question on Syllabus

The material I read says the population will increase to 9 billion by the year 2042. I don't really feel like there's a population problem now. If we're over 6 billion currently and doing okay, we can definitely accomodate another 3 billion in the coming years. We are going to continue to find ways to keep going. Buildings will keep going up, jobs will continue to be created, and it will all work out in the end. Earth is going to be fine, and I don't see us ever having to expand into galaxies.
