Population control needs improvement

This is a great time killer, my only gripe is the population of animals can spread ridiculously fast. I know theres a "kill all animals" option but itd be nice if there was a "kill all -insert animal name here-" option. Or for a wild card destructive experience an option for bigger lightning strikes that can start fires or a meteor that changes the shape of the land based on size and kills what it lands on with a small shockwave. Keep up the good work!
