Since we lack the gift of photosynthesis, we animals are destined by biology to be utterly dependent upon the lives of others
I think that this is something we have forgotten or twisted over time. Instead of viewing our relationship with other living things a dependency we look at them as our right. That we can take from them as much as we want because we are more advanced. I think that this is a very harmful way of thinking, and that we should be more considerate of our relationships with other things around us.
