We're close to peak population.

The idea we're going to run out of water is a James Bond movie, not reality.

Look at how productive China is compared to the US in growing calories. Then consider how little of China's land is fertile (12.6% arable vs 17.2% in the US).

China produces nearly 5x as many calories on 66% the arable land - nearly 6.7x more productive.

Then consider that India is FAR better suited for agriculture than the US, but is not considerably more productive.

We're not running out of food or water or solar radiation in our lifetimes.
