So true, IRescue. We humans don't understand the extent of our destruction until it wipes out a species like dolphins or until it nearly completely dries up Lake Chad. But underneath all of that is the everyday destruction of smaller insects and bugs (like caterpillars) that disrupt the food chain (like birds).
Unfortunately, we're like that frog in a tube of lukewarm water. We don't feel the heat until it boils. It's just frustrating. We all need to do something. When you're not in a room, turn the lights off for goodness sake. Walk more. Bike more. We all just need to go green!
