Toward the end of the world, human height is reduced gradually. true or false?

Correct! One reason is because kids/ our next generation is not getting the nutrients they need and not enough calcium. Rather, they are increasing their amount of caffeine, and as people know, caffeine makes a human body stop growing. That means they will be shorter. 

Help save the next generation! Less caffeine and more calcium! :D

True!
This is because of how unhealthy people are now adays, just think about the future.
Caffeine plays a major rule in this.
Starbucks, Dunking doughnuts, and more. The more caffeine people have, the shorter they get as they grow older. 

Only algae, oak trees, and bermuda grass produce atp by photosynthesis i am almost positive
