MEXICO CITY (Reuters) – Mexico City, one of the world’s most polluted capitals, is planting rooftop gardens on public buildings as part of a program launched on Thursday to combat global warming.

The smog-choked metropolis plans to replace gas tanks, clothes lines and asphalt on 100,000 square feet (9,300 square meters) of publicly owned roof space each year with grass and bushes that will absorb carbon dioxide.

Americans griping about the higher cost of food might want to take a look at what’s happening in places such as Kenya or Sri Lanka.

Food prices in those countries rose 25 percent during the past year, more than four times the inflation U.S. consumers saw, according to a new report by the United Nation’s Food and Agriculture Organization. In Botswana, food prices are up 18 percent.

Rainwater-Harvesting Expert Brad Lancaster Says Community and Conservation are Keys to Desert Living

Brad Lancaster is not wild about the word “green.”

“The term ‘green’ doesn’t cut it, especially the way it is being marketed,” Lancaster says as he drives back to Tucson after teaching several weeks of rainwater-harvesting workshops in New Mexico while also promoting the two volumes of Rainwater Harvesting for Drylands and Beyond. “This idea that we can buy our way green is bogus. We need to be asking ourselves: What are we trying to do, and how are we trying to live?”

Lancaster answers these questions in his books; the most recent volume focuses on how to use earthworks to harvest rainwater. A third volume is due out next year. Overall, Lancaster’s books teach desert-dwellers new ways to look at conserving water, while at the same time growing food-producing gardens, using solar energy and taking advantage of gray water from the shower or washing machine.
