Natural Gas Worse Than Coal
You already know this, but diets high in meat contribute to global warming. That’s because cows fart methane.
By burping, belching and excreting copious amounts of methane — a greenhouse gas that traps 20 times more heat than carbon dioxide — India’s livestock of roughly 485 million (including sheep and goats) contributes more to global warming than the vehicles the animals obstruct.

According to the Food and Agriculture Organization of the United Nations (FAO) agriculture is responsible for 18% of the total release of greenhouse gases world-wide (this is more than the whole transportation sector). [Source: Time for Change, 2008]
All that methane might be causing temperatures to rise. One of the solutions, being embraced all over the world, is to use natural gas instead of burning coal. Germany, for example, expects to replace nuclear energy with that from natural gas. But as New Scientist has pointed out (and governments have ignored), there is a big problem with natural gas…. It leaks methane, just like cows.
The US Energy Information Administration estimates that more than 8 billion cubic metres of gas are lost each year somewhere between the point of production and reaching homes across the nation.
…natural gas is made mostly of methane, which has more than 20 times the global warming potential of CO2 over a 100-year period. So gas that leaks from the system instead of being burned has a significant environmental impact.
…2.2 to 3.8 per cent of shale gas leaks out at the well site and an additional 1.4 to 3.6 per cent leaks during transport, storage and distribution – enough to make shale gas a bigger contributor to global warming than coal.
