Humans require food to continue to function, we overeat, and undereat. The more food we have the better we wil live
The piano could only be played with 12 fingers, which is rare because humans normally have ten fingers.
Keystone species, they kinda hold the food webs together
Predators and prey are both in a constant struggle for survival, foxes with bigger ears tend to catch more mice, and live longer, because of this, foxes with smaller ears don't live as long, pretty soon all foxes have larger ears. The same goes for prey, Mice with padded feet live longer due to the foxes having more trouble hearing them, pretty soon all mice have padded feet, and the cycle continues.
What can I do to assist??
