What is one thing in the natural world that you are curious about?

I want to expand my knowledge of the evolutionary growth of redwood trees and the role they play in the environment. The enormity of these organisms never ceases to amaze me. What elements of their surrounding environment promoted their extraordinary growth and how long did it take this evolutionary leap? Where are other species of trees similar to redwoods found and how do their environments differ? What type of wildlife do redwood forests support? I hope to spend an extended amount of time studying redwood trees at some point in my life so that I may answer all of my questions pertaining to these colossal structures of nature.
