Stop fracking. It's the most expensive way to get oil out of the ground, and wouldn't be cost-comparable to renewable energy sources if the industry wasn't empowered to use dangerous amounts of water in drought-stricken areas, use eminent domain to steal land for pipelines, and generally externalize every cost, making everyone who doesn't have lobbyists foot the bill for their reckless behavior. At this point, the only reason fracking is profitable is because government is propping it up. Solar and wind (particularly in places like Texas, California and the southwest) is cost-competitive (or even cheaper, if you calculate long-term, because solar panels and wind farms have a very long productive lifetime and quite low ongoing costs, unlike oil and gas), if you take away the crutches that our government provides oil.

As for food, meat and dairy doesn't need to be produced in water-starved environments (and probably doesn't need to be consumed at the rate that Americans consume meat and dairy). Again, industry gets a pass and gets to socialize environmental costs that they simply shouldn't be able to externalize. But, he who has the money and the lobbyists makes the laws.
