3M (aka MarkyMarkMark)
Even our nearest genetic cousins (Chipanzees) eat meat occasionally though. Admitted not very much, and they don't farm it! Not sure there's enough fruit trees and edible leaves in the world either for us all to live their lifestyle. The real problem is there are more people on the planet than we can support without doing something quite a bit different from what we've done so far, I guess. |

If you look at our teeth and digestive tracts than we are very much omnivores. This means we need some meat and/or fish but not all the time and our nutritional needs can be met by veggie options. Apart from some things, like bio-available B12 and the main reason for keeping chickens: eggs are full of it! If you are vegan, you do need to supplement certain things, so that says enough...

Sorry H, but we don't "need" meat or fish. I've been a veggie for over 30 years now, and haven't (knowingly) eaten either in that time. I've not exploded, or imploded, and am (touch wood, and long may it remain so) reasonably healthy for my age. |

bbc.co.uk Not heard of this tech before. So simple. Great big pile of sand is heated up by spare energy generation, and released (up to months later) as heat. Presumably could also power a turbine to convert back to electricity, if that was the demand rather than just heat? Brill!  G

Spain stores solar energy in sand for a large solar plant outside Madrid. They did this many years ago - I think about 2015

I get really excited when I hear about low impact technologies that can really help us use renewables at scale. I'm sure it's not the whole answer but feels like an important step. 5 years ago there were hardly any wind turbines and look at the scale now. Maybe we can actually stop destroying our planet? G
