He would draw the animals

We're very hungry for fossil fuels too.

Here, I deliberately chose this because it is a man buying a vegetable.

So we must find other solutions.

You guys are growing food again?

That means that we have now more food available than ever before in human history.

It's very consolidated, and the foods that are produced lead to the foods that we eat.

And we know that the issue is not just production of food.

Aside from transport, cars, trucks and airplanes, agriculture is the most fossil fuel intensive industry.

Nitrates, phosphate and potash.

And meat, in fact, is something that costs a lot of our agricultural production.

The main aim is just saving seed.

The world today needs to advance its production of food.

The second factor is the services we use.

In autumn some animals store food for the winter.

The world today needs to advance its production of food.

which I find is somewhat ironic.

Think about cars, food, houses, fauna, flora.

Cars are factory products, while foods are farm products.

The scale of the challenge ahead Richard is talking about becomes clear when you look at bio fuels.

The use of biofuels means that less land will be available for food production.

That's the European average for new cars.

Lions live on other animals.

A bit higher up are the fruit trees, like apples, pears, medlars, plums and quinces.

Following the invention of fossil fuel derived fertilisers and pesticides there were massive improvements in food production, allowing for increases in human population.

We start out with nine.

These animals feed on grass.

Within the Solidarity Economy, the production respects the natural envioronment

But the only way we think that biology can have a major impact without further increasing the cost of food and limiting its availability is if we start with CO2 as its feedstock, and so we're working with designing cells to go down this road.

And so that the cost of goods is literally how much did it cost to buy the metal and the paint and provide the electricity to make those 3 million worth of widgets.

Eat. We want food.

Food and the cold and our shoes.

What's the most important things you need to do for the business to make the business model work.

Food, drugs, power, clothing, for free.

You'll get proteins in any kind of food anyway.

And this is this voracious predator launching a sneak attack on this poor little unsuspecting jellyfish there, a by the wind sailor.

A tiger is a beast of prey.

They're at the start of food chains.

Doubt is our product,

But when you think that every day for a city the size of London, enough food has to be produced, transported, bought and sold, cooked, eaten, disposed of, and that something similar has to happen every day for every city on earth, it's remarkable that cities get fed at all.

This will mean that growing food will become difficult.

But the small animals that eat insects are being eaten by larger animals, still larger animals.

Why are we talking about microalgae?

In the face of all these challenges, global food production must double by 2050 to feed the growing world population.

The algae that grow produce oxygen, as I've mentioned, and they also produce biofuels and fertilizer and food and other bi algal products of interest.
