Say bacteria. People think infection. Or yogurts.

But in Chile, bacteria are being used to get at something this country heavily depends on: copper.

Chile is the world's biggest copper exporter, and has the planet's largest known reserves of the red metal.

The world is going through a total metamorphosis. There is no time in history where we have achieved so much, which gives me hope for our civilisation being the first in all of human history to not collapse. But the biggest retardant to progress, I think, is not the politicians, but the population who are against progress because of religion, prejudice or being gullible. My family is among the prejudice section and I find it very frustrating trying to persuade them of things when they have such a galvanised outlook on something. Especially with GM where they refuse to buy GM products because they "don't like the thought of it" and they don't think "we should go down that road".

Well, in the coming decades, we futurists will have to be prepared to let them go as we progress forward. The world will become strange and blurred for them.

I think it would be neat if we could genetically alter these critters to help us mine rhenium, which is one of the most in-demand and rare elements on Earth.

This actually isn't surprising to me. Bacterial metal mining was talked about (albeit briefly) in a science fiction novel. The characters called it "bog iron" or something like that. There wasn't much information on it in the book, so I did some research and found out more about it.
