Natural - but artificial - as in lab-grown food. It's natural, made out of natural proteins, but made in a lab, so artificial.
The reason I'm bringing this up for debate is because we're slowly - ok not slowly, RAPIDLY - depleting some of our precious food stocks around the world. I personally like to eat tuna (canned), because it's packed with protein, good for your health and goes excellent in salads. But the tuna is unfortunately heading for an unwanted extinction from the world's oceans, due to serious overfishing, depletion of stocks and increasing demand worldwide. In other words, if this doesn't stop, then in a couple of years we'll have no more tuna, no more sushi and we just destroyed an entire species of fish that is a key link for the ecosystem.
For a while I've kept thinking about lab grown food, made out of natural materials - I saw a video of researchers making a lab grown meat burger. It tastes like meat, except it's not made of meat - well not the traditional way. It's made out of bovine stem cells.
So sustainable, no serious problems to the environment and no cruelty involved.
That sounds like a great idea - except that it might be years away until we see it because we don't know the effect of it for the moment. And plus we can't mass produce it yet, so there's still efficiency to sort out.
However, until this happens, we might run out of important sources of food such as different types of fish because we depleted the stocks and we didn't find proper alternatives.
Thoughts? Would you eat lab-grown food?
