Question: What you said about being'imapcted by humans', does that mean like when we litter, we are impacting on the environment?

Yeah, and bigger stuff too, like when we clear down trees to build stuff, or when we build new roads that might cause road kill, or when we change rivers by building dams. And its ok to do these things but we try to find ways to not cause too much damage or to replace whats been removed.
