We can easily grow enough food to feed humanity.
The idea of specialising on a few crops terrifies me. We need diversity, not monocultures.
Security in any system ultimately relies on multiple independent redundant systems.
Local diverse mirco-managed ecologies can feed people very efficiently – just doesn’t make profit for mega corporations that want to control everything.
We can feed 10 billion vegans from California and Texas. It’s meat that takes a lot of land area.
Continue the work by all means, it is interesting at several different levels, and let’s not pretend that it is required to feed humanity – that is pure twaddle.
And sorry – making green people isn’t an option. We need about 300W continuous, which would require a skin (leaf) area over 5 square meters (allowing for night time, cloudy days, etc). Easier just to grow plants and eat them.
I’ve been vegan for 5 years now Gordon – body is much the same shape it was when I started university (over 40 years ago) – other than wrinkles and sagging ( ;( ).
To get benefit from chloroplasts we would need to be outside – exposed to sun and UV. We need a little of that – but not too much.
I’m quite happy spending most of my time indoors, where chloroplasts would only be a drain on energy – not a boost. Much of the time I am outside social convention requires me to cover up. Not quite so bad here in NZ than in the USA – I was stunned visiting there to meet the “no shirt, no shoes, no service” rule – having been barefoot for 40 years here in NZ, and never having a problem with service.
