What have you done today to lower your impact?
We are washing away the foundations of our existence on every front. It is high time we move from crashing about on the planet like a bull in china shop and find a way to go forward with intent. We must find systems of living based on sustainability. The systems and tools exist, it is up to each of us to adopt them.

Vertical farming w/video - By Robb
If the population continues to grow as predicted, something I don't personally believe is possible, we will have nine billion humans, give or take half a billion, by 2050, mostly in cities. How will we feed them all? It is obvious the current methods of food transport are unsustainable and we would need 10 billion more hectares of farmland to do the job. So would we cut down all the remaining forest, the only effective carbon sequestration we have and are likely to have in the next fifty years, and plow under an area the size of Brazil with all the attendant water pollution, loss of diversity, and global warming effects of current industrial farming? I don't think so. Even if we hold the population at current levels cities need to become sustainable just as a households do. This means local food for one thing, closing the nutrient cycle by recycling waste for another.
I don't tend to favor high tech solutions but this urban farming concept, a 30 story tower that could feed 50,000 people is all organic, provides local food, recycles waste, and provides jobs is attractive. I wonder, could it be retrofitted to appropriately situated towers already in existence? Even if purpose built it would certainly be a better allocation of resources than some multinational headquarters full of computers. Here's a more in depth article on this concept over at Plenty magazine.
