how intelligent are we?

People will have to get used to the idea that never-ending economic growth and ever-rising living standards are impossible on a finite planet. 1) POPULATION If people live longer, and average family size is small, we cannot remedy the situation by constant immigration or large families. The population of any country cannot grow for ever. The resources are not there. 2)RESOURCES We have trashed the environment. Despite what some think, we are totally dependent on the environment for our food, fresh water, even the air we breathe. We are very likely to run short of energy and food - perhaps soon. If people realise this, are prepared to change their lifestyles & are willing to consume less & use new technology as much as possible the human race can survive. Otherwise - after the rioting - famine, war & disease will reduce the population to what the planet can sustain. The breakdown of civilizations has happened before. How intelligent are we? We have to wake up.
