Obesity, cows and climate change
I was flabberghasted when I learned that cows produce as many litres of polluting gases as a car does in a day. And I’ve since been trying to run over as many cows as possible to reduce the carbon footprint of my huge four-by-four.
But my novel solution to the problems of climate change has hit a brick wall, because rising levels of obesity in humans are now being blamed for damaging the environment.
Research in the International Journal of Epidemiology compared the needs of a lean population (for example Vietnam) with those of the population of the USA, where 40 per cent are obese. The weightier population required 19 per cent more food energy and made greater use of cars.
At the same time, the United Nations suggests that we should be eating less meat because meat production causes 20 per cent of global emissions.
There is an endless list of statistics of this kind because, in short, everything we do damages the planet. But it’s also becoming clear that many of the ways in which we damage our own individual health have repercussions for the environment and everyone who lives in it.
