What is "fracking?" It’s removing natural gas from the ground–and there is LOTS of it right here in the US, so if we produce cars that run on natural gas (as lots of trucks do already), then we can solve our oil dependency problems. HOWEVER, fracking uses LOTS of water (which we are ALSO short on) AND it is not necessarily emission-free.

Wetlands, permafrost, termites, oceans and freshwater are all natural sources of the potent greenhouse gas methane. However, the majority of the methane that is changing our climate is caused by human-related activities such as fossil fuel production, biomass burning, waste management and animal husbandry (due to cow farts). The release of methane into the atmosphere by cattle and other large grazing mammals is estimated to account for 12 to 17% of the total global methane release.

Cow belches and farts are a major source of greenhouse gases that affect climate change even more than vehicle emissions. A new type of cattle feed that is supplemented with oregano, developed by a dairy scientist, could help reduce cow gas emissions by 40%. It also improves milk production.

PhysOrg.com quotes its inventor, Alexander Hristov, as saying, “Cattle are actually a major producer of methane gas and methane is a significant greenhouse gas. In fact, worldwide, livestock emits 37% of anthropogenic methane.” (Anthropegenic methane is methane produced by human activities, such as agriculture). And methane has 23 times the global warming potential of carbon dioxide. [Thus] “any cut in the methane emissions would be beneficial.”

But we don’t know why – We don’t know why it happened before but it seems to be happening again: Huge quantities of methane below the Arctic seabed are showing signs of leaking out into the atmosphere, which would be the tipping point for climate change.
