A whole forest can’t get up and move a bunch of miles away. The same can be said for reefs. They grow, like, a few centimeters every year? It would take years to make any progress in moving. On top of that, it’s not just the temperature that is the problem. (Although I’m fairly sure that it is a big one.)
Why can’t you and every person in your city each move your whole house to avoid a flood, earthquake, tsunami, or other natural disaster? Just move your city to a new location that won’t be affected!
Coral reefs are *anchored to the floor*. They are rocks full of tiny living creatures that can’t survive in just any old part of the ocean. It takes centuries for them to grow, and mere years for them to die.
They can. It just takes time.
That’s the big problem with man made climate change. Unlike natural cycles, which occur over thousands of years, giving flora and fauna time to adapt with the changing climate, man made climate change is basically instant from a geological perspective.
It’s mass upheaval and mass extinctions.
