In addition to contributing to erosion, pollution, food poisoning, and the dead zone, corn requires huge amounts of fossil fuel - it takes a half gallon of fossil fuel to produce a bushel of corn.
The American Republican Party is the last political bastion of the fossil fuel industry - now so in tow to the fossil fuel industry that it cannot face up to the realities of carbon pollution and climate change.
A revolution in humanity's use of fossil fuel-based energy would be necessary sooner or later to sustain and to extend modern standards of living. It will be required sooner if we are to hold the risks of climate change to acceptable levels. The costs that we bear in making an early adjustment will bring forward, and reduce for future times, the costs of the inevitable eventual adjustment away from fossil fuels.
It is a fact that, today, up to seven million people a year are dying from fossil fuel pollution.
The fossil fuel industry for too long has shifted enormous costs of carbon pollution onto the public.
If your child gets asthma, the fossil fuel industry doesn't pay. Or if there's a natural disaster, the bill is paid by the taxpayer, not the fossil fuel company.
I did very much like [Barack] Obama's attack on fossil fuel subsidies for fossil fuel companies. We asked for that in demonstrations and petitions, and now we'll try to push it forward.
Fossil fuel companies and their allies are funding a massive and sophisticated campaign to mislead the American people about the environmental harm caused by carbon pollution.
We're clearly coming to the end of the fossil fuel era. We have the technology to shift to renewable energy, we have the will of the people. The only thing that's keeping us back is the fossil fuel industry's hold on our political system. That's what we need to change.
When you think about the current present value of the fossil fuel reserves that are on the books, the current fossil fuel companies, the last time that that much wealth was at stake was when the South fought the Civil War.
Of course methane is a fossil fuel, but as long as it is burned efficiently and fugitive emissions of methane gas are minimised, it is a less harmful fossil fuel than coal and oil and is an important way-station on the global journey towards low-carbon energy.
It is a fact that many of the wars and conflicts happening all over the world are aggravated or fought strictly for geopolitical fossil fuel energy interests, and many of the world's most dangerous regimes are funded by fossil fuel dollars.
The great thing about cheap natural gas, again it's cheap, and it provides a cleaner alternative to coal. But it's still a fossil fuel, and because it's still a fossil fuel, it still emits carbon.
Most Republicans are not prepared to stand up to the fossil fuel industry because they get a lot of their campaign funds from the Koch brothers and other people in the fossil fuel industry. That tells me why we have to reform our campaign finance system.
We promote new fossil fuel infrastructure, from airport expansion and coal mines in the U.K. to oil pipelines in the U.S. Investments are meant to build and secure our shared future - but all these fossil fuel investments are directly fuelling the climate crisis that threatens to undermine that future.
Most climate debates have focused on cutting the use of fossil fuels. But besides a few high-profile scuffles over fuel extraction in vulnerable wild places like the offshore Arctic, political leaders have ignored fossil fuel production as a necessary piece of climate strategy.
