Oxygen makes the world a better place! So plant some bushes and trees, or dig a pond and let there be algae. (Yipee!) I suppose its best to do this in a poor ecosystem like a lawn or a desert. An idea from douglas macrae smith

But if you dig in a desert it´s hard to find water. I like the idea of planting trees, though.

Not many deserts in holland, so not really a good idea - however for those with deserts near by, there are ways and means - if interested check out permaculture links or this one

Inspiring talk indeed, thanks for posting. I agree that even deserts are full of possibilities. Have a look at the second item in this video: http://www.youtube.com/watch?feature=player_embedded&v=gFiyirnsHJU on greenhouses in the desert, using solar power and seawater.
