Deforestation, urbanization, travel by humans have poked the 'hornet's nest' so to speak. We don't live in balance with nature, we encroach on it and destroy it. Humans are incredibly greedy, and humans are aware we will die, animals are not, so humans try to keep that idea at bay by acting like we are immortal, so we attempt to dominate and control in that effort. Some do it far more than others, but everyone pays the price when the top dogs' control everyone else. Gates is an example of that.
