Think more deeply about your first question. Regardless of what anyone says, we all act in what we perceive our own best interests to be. It's human nature to do so. People like Mother Theresa who dedicate their lives to helping others are every bit as selfish as the most stereotypically greedy capitalist. The difference lies in the perception of what is actually in our own best interest. Mother Theresa didn't help people because they needed it. She helped them because it made her feel good to do so, and because in her belief structure she thought that doing so would provide her an eternal reward. The motivation of the stereotypical greedy capitalist is the same, but his thoughts are confined to the material world, and to a much shorter time span. People will never think as a species, they will think as individuals. Did we as a species prey on the ancestors of modern livestock until they were erradicated? As far as your contentention that the person who thought this up could be a nice guy, ask yourself how nice a person who figured out the greatest possible threat to the planet and then did nothing but whine on the internet about it really is.So you don't believe that man, as a species, will put his own self-interest above everything else to the complete destruction of habitats and species, as long as the ends are met? That we will prey on everything until we completely erradicate it?
The parallel of us and viruses is quite fitting. A virus multiplies until it eventually kills the host or the host kills it. We are in the process of killing our host. It's just takin' us a long time to do it...it's a pretty big host. Anyone who denies that is practicing a very dangerous form of self-delusion. Just look around the planet at what we are doing to it. Look up the food stocks decling on land and in the ocean. Deforestation, pollution, consumption are all taking a slow, inexorable toll.
Unless we, as a species, decide to do things differently, what do you see as the inevitable outcome?
...and just because I don't have too much faith in our species as a group, doesn't mean I feel compelled to eradicate the rest of y'all. I can be misanthropic without sending you all to Valhalla.
