Biodiversity.

I think we should save the plants and what not because its our right to help out the little man, or in this case, the little bug. Antibiotics were first found through studies of plants and bacteria as well. Everytime we lose another species or animal we're losing a chance to discover new things. Or even possibly new medications. We're not the only ones on the planet. Nor were we the FIRST on this planet. These animal/bacteria/bugs were here way before us, and it's our job now to help them the way that they have helped us. We have damaged them, and now it is our turn to give back. They don't understand why they are becoming extinct and if we pay attention, we might be able to figure it out and stop it from happening. We're damaging the earth, which in turn is their earth as well, the least we can do is make it an equal world between human and plant/bug/animal and so forth, even if we can't make it equal between humans.
