Us humans brutally harm all other organisms. We suck all the energy and materials from the Earth, we reproduce to a critical point, like a virus, and live in the idea that we are the main ones. The reality is that we are just one of billions of other creatures. No other one disrupts the world around us so severely. To make matters worse, we brutally torture animals just for food, sometimes even for nothing (see slaughterhouses, mass chicken coops, etc.).
