Firstly the whole world wide economic system is based on growth. Growth is dependent on increased population. More houses, more sinks, more dishwashers, more SUVs, more everything. (See Economics102)
The second reason we can't talk about it is that we don't know what to say. No one, except the Chinese, has come up with an acceptable method of population control.
Thirdly, no one except the Chinese sees the elephant. We are so busy concentrating on the other stuff in the room that we totally miss the elephant.
It strikes me as incredulous that very few have the
ability to understand that the planet is a limited resource. In Canada
on our west coast the Salmon have returned every year to spawn in one of our
rivers. This year they did not return, so our brilliant government has
launched an investigation into why they did not come back. No doubt
this will cost tax payers millions of dollars. Well, to me, it is a
Somebody ate them.
(Just deposit my million in my account.)
The video to the right should be on the Donkey (thinking) page but it is here to show one way that our brains can block out the elephant, or in this case, the ape.
