Air quality in the US has been improving since the 1970s, but that progress may be backsliding and 43% of Americans are now living in places where they are breathing unsafe air, according to the American Lung Association report.
Recent research has estimated that by 2030, the planet will be generating at least 5bn tonnes of poo each year, with the vast majority being deposited by livestock. With 80% of farms in the Netherlands already producing more cow dung than they can legally use as fertiliser, and China resorting to drastic measures to try to reduce the amount of manure being discharged into rivers, scientists say this is a major environment and health challenge.
Polluted air causes more than 6 million premature deaths per year worldwide, including roughly 1.6 million annual deaths in India. Here, a sobering new estimate of the likely death toll from one of air pollution’s ingredients — ozone — suggesting that without aggressive reductions in emissions, more than a million Indians will die prematurely each year from long-term ozone exposure by 2050.
