I'd been round the back.

Moving on to my personal experience,

CH4, in the atmosphere of Mars.

So let me just make it very clear what's going on here.

One of the questions from the audience is, with fracking and the natural gas process, what about the problem of methane leaking from that, methane being a worse global warming gas than CO2?

The hall was filled with such a large audience that there wasn't even standing room.

So it's a bit counterintuitive, but by collecting methane and burning it, which converts it into carbon dioxide, you're actually dramatically reducing the greenhouse gas emissions from the landfill.

For someone who's done a lot of counterterrorism work,

Already in some shallow lakes in Alaska, methane is actively bubbling up out of the water.

Here's Hellas Basin, a very very different place, geologically.

I was looking for the source of the landfill... they're dumping on our mountain.

And these molecules, especially methane and ethane, can be liquids at the surface temperatures of Titan.

The pirates buried their treasure in the ground.

They each have about 5 pounds of lead in them. Lead! As in lead poisoning!

J.F. Kennedy was buried in Arlington Cemetery.

Dogs often bury bones.

You're looking at brine pools formed by salt diapirs.

like gasoline or sulfuric acid, methane, and nylon.

Dumpster. Oops.

The staff are so excited about the project.

And in their area they had a lot of shops and restaurants that were producing lots of food, cardboard and plastic waste.

What the probe came down in was basically the Titan equivalent of a mud flat.

And that would be very interesting in the developing world.

Once carbon this right here is a molecule of methane, right?

He was buried in this graveyard.

We preprogram it.

Then she flies through the forest

The EPA estimates, in the United States, by volume, this material occupies 25 percent of our landfills.

Except it's a lot colder, and that atmosphere is heavily made of methane.

Of course these clouds and waterways don't actually contain water.

The landfill gas is made up of, generally, 50 methane and the rest carbon dioxide and some other volatile compounds.

And you can see there are three distinct regions of methane.

And here you can see methane, if that's the way you're going to go, that there's plenty of methane natural gas is methane, methane and natural gas are interchangeable but if you decide that you're going to use some methane and I'm gone, so it's up to you but we do have plenty of methane hydrates.

TATJANA VUJlC The beauty of this system is that it uses the methane to run a microturbine, which generates electricity.

They buried him in the graveyard by the church.

Temporary signs are a great way to point people in the right direction.

We were also interested to see that, although we've obtained greater diversity of bacteria biodegraders from the bird habitat site, we obtained the most efficient degraders from the landfill site.

And finally, there's deforestation, and there's emission of methane from agriculture.

The term deep six comes to mind

And that was brought into force to try and deal with the mountain of stuff that is just being made and then living for a while in our homes and then going to landfill.

So, instead of wasting money, dumping wasted food in landfills, we can remake waste into an asset, putting it back into our food system to make it more sustainable, all with the help of the humble worm, the tiny organism that can help us change the way we look at food's place in our lives and our place in the world, as long as we give the little guy a place at our table.

We have diverted 148 million pounds that's 74,000 tons of used carpet from landfills, closing the loop on material flows through reverse logistics and post consumer recycling technologies that did not exist when we started 14 years ago.

She was interred at Westlake Repository, Little Chute, Wisconsin.

This region right here is the reactor.

This double front door here with the three light transom, that was headed to the landfill.
