Precision fermentation: catastrophe lifeline
‘Farm-free’ food for people will come later, but the basic elements can be combined to suit human tastes too. In the future, if one of these catastrophes should strike, we can just switch from feeding the animals to feeding ourselves. We weren’t even looking for it, and we’re getting free survival insurance.
The asteroid 2023 DZ2, pictured on March 21, 2023. It flew by our planet at 27,000 kilometres per hour, closer to us than it was to the moon and was less than one-hundredth of the diameter of the gigantic asteroid that took down the dinosaurs 66 million years ago.
