In one of David Suzuki's books he laments that if aliens were observing us they would have to conclude that we were an insane species.
- if we hunt a food species faster than it can reproduce, it will go extinct and can not be used as food in the future. Yet this is what we are doing to fish and other aquatic species we depend on
- we need clean air and water to survive, yet we contaminate both by dumping our wastes into them (eg. exhaust, sewers, pollution, etc.)
- we are aware of health/environmental problems, (eg. ozone layer, global warming, pollution, smoking, etc.), but will actively resist stopping the causes until we are forced to
- we are aware that exponential growth is unsustainable in any form (eg. population, crops, finances - we live on a finite planet), yet we continue to act as though it can be although that logically leads to our own destruction
