Certainly! In the near future, antibiotics will become a thing of the past and life expectancies will return to at least where they were 150 years ago, if not less. Superbugs will continue to become more deadly. The slightest infection could kill animals as well as humans. Overpopulation will become a HUGE problem, so much more than now, and the problem will compound itself ever more rapidly. The oceans gyres are already stuffed with plastic and other garbage, and the overflowing garbage will end up EVERYWHERE! There will be no edible fish left in the oceans in 50 years. I read this somewhere.
