National Geographic: Story on Food and farming techniques (this month AQUACULTURE)

so nat geo has started a multi month series of articles on food and how we are going to feed an ever growing population without more damage to the ecosystem as a whole. very interesting stuff both last month and this month. its quite in depth this month of many forms of aquaculture and its many uses (as many of you know water as fertilizer) anyways if you get the chance snag a copy at your local supermarket. its well worth the read and might give you some ideas for your own setups.
