Except one theory holds they don't concern themselves beyond their own lifespan, or at most 1 generation ahead. It's the media, too, owned by them that perpetuates lies re world resources. My Master's thesis was on the world water crisis. Ppl think there aren't enough resources; food, water. Oh, there are. There very much are. It is the DISTRIBUTION that's lacking. It's down to human greed, plain & simple. Greed, hatred, delusion. I know nothing about fossil fuels, etc. i do, however, know alternatives are ignored by the powerful in favor of keeping car manufacturing going. Were efficient pub trans a priority, we'd have it.
