Answer 1

just like all the other plants and animals, they're the result of evolution, and there is a good part of the environment that they are able to make use of.

they don't symbolize anything, they just are.

just like mosquitoes, and jellyfish, and poison ivy, and flu, and you, just are.

Answer 2

The Earth has trees because it makes a happy & healthy place for all living things. Like everything of this World, Trees are just another piece of the giant puzzle. The purpose of the tree is to provide shelter, habitat, and convert carbondixoside in the breathable air(for us humans, and alot of other animals).  Trees also help to create a rich environment, protecting the ground from erosion and loss of moisture. There is so many different Types of Trees becuase diversity ensures survival. Another reason that there is many kinds of trees is becuase there is so many unique environments, climates, elevations, and weather. They needed to evolve in ways to adapt to where they were. They were faced with new challanges and needed to evolve,...kinda like humans. It's still happenning today, it's great to be alive.
