I suggest that there should be a mass removal option of vegetation like trees and sugarcane, though, this can also imply for non-vegetation like crystalline and diamond growth, pretty much anything that has a spread rate. The reason for this is when you have a large map, but it's already starting to spread its own vegetation quickly, making it hard to contain. It wouldn't be a problem if it weren't a performance issue. I think it would be great and alters minimal changes to the vanilla style of the game.
