We should create a new form of democracy. We should have faith in people and give them the opportunity to spread ideas, contribute to make better ideas, and vote. Equally on a local and global level. "Don't try to save the world, but help people to save their own world."

• #### A reply onTalk: Paul Gilding: The Earth is full

Mar 10 2012: That was the exact point of this talk. "there is a solution for this type of problems yet very few invest in the proper ones" Because they can't believe the magnitude of the problem. We are running out of time.

And about the planty of space we have.. Scroll down a bit for my other comment..

I agree with you about the cities but we don't have plenty of space. This shit is sirious!

#### A reply onTalk: Paul Gilding: The Earth is full

Mar 10 2012: The size of the continental area of the Earth is 150.000.000 sq km.
(This is every square kilometer we he not counting the oceans. But it includes every desert and ice coverd land as well.
http://en.wikipedia.org/wiki/Continent
http://www.enchantedlearning.com/geography/continents/Land.shtml)

There is 7 billion people.
(http://www.worldometers.info/world-population/)

It means there is 21.500 sqare meters of land for each person. And that is a 146 m wide and 146 m long piece of land.

On 21.500 square meters it would be really hard to grow the amount of food in a year that on person needs to eat in a year. And this is including all the deserts, ice, etc as well. The actualy usable soil most be maybe 70-80% of it. But we are destroying the soil as well.

How is it even possible.
The answer is simple: there are over 1 billion people on this planet who are alredy starving. And 25.000 of them starve to death every single day.

If there were 40 times more people..
than every single person would have 535 square meters. And thats 23 meters x 23 meters.
It’s 20meters x 20 meters of soil at best.

How would you grow enough food for youerself on a field like that?

Think!
