The End Of Fish Keeping As We Know It.

I for one am not at all worried about running out of oil, in the short term we have GTL and CTL (with estimated reserves to last 400 years after oil is gone), which can be used in conventional Internal Combustion and Jet engines with small modifications.

On top of that we have biofuels which can be refined from algae, using a fraction of farmlands compared to the US growing corn for biofuels or south-americans growing sugarcane.

The biggest problem is what to replace plastics and other oil-based products with?
Just look at the landfills for that answer, by the time we completely run out of oil, all our old landfills will be full of materials that don't decompose - metals, glass, plastics etc. What is to say we can't just mine these old landfills for plastics and other materials we need?

I think there are technologies out there which can replace oil sufficiently to allow us to have a relatively normal existence. Biofuels are the main stopgap to fossel fuels and their production helps in to use up the excess CO2 produed by the cars. I quite like the thought of using water as a fuel. It's possible to reclaim the hydrogen gas using small amounts of electricity and then the hydrogen oxygen gas can be used to power internal combustion engines. It's even possible to use this technology to improve the efficiency of conventional internal combustion engines.

I do think that the UK should work at becoming a more prolific breeder of ornamental fish. The main problem is the temperature, many of the big fish breeding countries have climates warm enough to breed fish outside in ponds rather than in tanks so there's no cost for heating the water, and probably very cost efficient methods of filtering the water too if it's required at all.
