Plants take in CO2, and combine it with water, to build carbohydrates – producing helium gas and emitting X-rays, as the plant does Molecular Nuclear Fusion
Which makes biology the worlds' experts of nuclear fusion on Earth.
So we dredge the sea floor – and wash most of the salt out in river estuaries. We produce soil mats – impregnated with grass seed.
We also plant seedling in this soil, to stabalise the new soil.
To make water, we need to suck sea water up 1m, and it boils. So we pump the fresh ater to the top of the new fields. All the pumping being done by solar power pumps – which charge up batteries, to carry the cycle through the dark of night.
As the plants get established, we rec;aim more desert inshore. So gradually the deserts turn into grass lands. We cut the grass, and feed penned animals – and use their dropping to fertilise the fields.
In the Jurassic the deserts were lush rain forest – and there was 54% more life on Earth. At the end of the Jurassic, 85% of life on Earth died – forming the Fossil Fuels.
Buring them increases modern life on Earth. Plants on the land, and bacteria in the seas, cap average global CO2 at only 2 parts per million.
