The map reveals large carbon dioxide concentrations around South America and Southern Africa
It’s possible to dream up thousands of small ways to make a gigantic event like the Olympics more sustainable. A London-based group, for instance, asked architects to design a solar-powered information booth that would highlight recycled materials. The winner, announced this week, took its design from the Olympics’ iconic ring logo and used recycled steel. The second-place design involved floating balloons that would suck carbon dioxide from the air. Another runner-up would have crafted a running track, bent into a building of sorts, from the recycled soles of Nike shoes.
Amidst the depressingly deadlocked climate talks in Cancun, a side event dedicated to agriculture and climate change provided at least one positive story. Gustavo Mozzer, a scientist with the Brazilian Agricultural Research Corporation (EMBRAPA), a government agency, described the country's Low-Carbon Agriculture Program, which he claimed would "cut direct farm carbon dioxide emissions by 170 million tons a year, and save as much again by curbing the invasion of rainforests by farmers."
