Re: Even if...
Or to encourage everyone to subsist on a diet of baked beans and walk around with a "gas" bag over their bums.
The first 100% renewable food supply:
1. Eat beans.
2. Fart into bag
3. Collect bags and burn gas to power bean processing factory, farming equipment and even provide fuel for the lorries which deliver.
It's amazing that no-one has though of this before. Please crowd fund me for 20 million pounds so I can live the high life, oops sorry, start the investment process to take this project to the world.
