How many people can live on planet earth? - BBC Horizon (HD)

In a Horizon special, naturalist Sir David Attenborough investigates whether the world is heading for a population crisis.
In his lengthy career, Sir David has watched the human population more than double from 2.5 billion in 1950 to nearly seven billion. He reflects on the profound effects of this rapid growth, both on humans and the environment.
While much of the projected growth in human population is likely to come from the developing world, it is the lifestyle enjoyed by many in the West that has the most impact on the planet. Some experts claim that in the UK consumers use as much as two and a half times their fair share of Earth's resources.
Sir David examines whether it is the duty of individuals to commit not only to smaller families, but to change the way they live for the sake of humanity and planet Earth.

And I don't understand why people hate LBGT people , at least we don't reproduce , we adopt your children

2 sets of problems: population growth & over consumption.

Over consumption is Westerners problem. E.g., at 4% of the world's people, the USA consumes 25% of the world's resource.

But population growth can be easily slowed by MERELY giving good education to women.

Over consumption, unfortunately, can't be dealt with as easily, regardless whether a person is rich or poor, educated or uneducated. In fact, the more educated & richer a person is, the more resources he/she consumes & wastes.

@darthvader5300 Oh , ok

[darthvader5300]

@TheWizardWeiss Thanks but I want to clarify one thing. It is not a religious statement, it is a historical philosophical truth based on a truthful and honest statement from an unnamed scientist who said it during the heyday of the space age of the 60s and 70s and his statement is "Earth is the cradle of humanity but humanity cannot live in the cradle forever".

@darthvader5300 Sorry I don't discuss religious stuff have a nice day

[darthvader5300]

@TheWizardWeiss No one has any right to make those God like decisions for other people. If you want immortality then all you have to do is look at the cradle from which you came from and from which (hopefully and pro-natally) your children will come from and in their eyes you will see the hope of humanity if given a full chance to fullfill that hope. Man is not plastic, he is infinitely creative. We do not live in one planet but in a solar system full of resources just waiting for us.

@qwertyui90qwertyui90 Still the number of people would increase , at least half of the world population shouldn't reproduce I mean half of the couples , But even if that policy was adopted things wouldn't work out as expected mainly in africa , I guess we will still let it for the future because you know humans only do something when it's too late

[qwertyui90qwertyui90]

How about we just have a 1 child policy accross the world ?

@not2b8b4u You have no faith in humanity's humanity in nurturing the value of human life. Man was created by this planet for a purpose. Earth is the cradle of humanity but humanity cannot live in the cradle forever. Thermonuclear war? We're prepared for that for decades, we can rebuild modern human civilization with 3 to 5 years after peace has been established. I have seen the horrors of war. you probably have not seen it, when one has experience a war, no one wants it except when force into it

[darthvader5300]

@not2b8b4u These ideas has been in existence since the 60s and 70s, it is their lack of application which is the problem, mostly political in nature. Professor John Todd's Living Machines, Solar Aquacells, Muskegon project, etc are already in place but not applied extensively because mainly of political reasons and their economics has already been solved.

@not2b8b4u It is apparent that you have not heard of our almost 400 abiotic oil and gas wells nor our Russian BREST reactor power plants that can breed it's own replacement fuel and consumes it's own nuclear wastes and capable of being redesigned to breed more nuclear fuel than it needs.
