From reader MH:

This one paragraph should end all arguments about food shortage or the need to drill for oil based energy.

“The standard argument that we hear against immortality is that “the planet would become overcrowded. That is a lie. First of all, at present, if we gave each person a Chinese style subsistence farm, we could fit the entire population of the earth in the State of Texas. Also, WITH ENERGY TECHNOLOGY THAT HAS BEEN SUPPRESSED, WE COULD CREATE ENTIRE NEW ECO-SYSTEMS IN THE DESERTS, THE FROZEN WASTELANDS AND UNDERGROUND. We do not even have to invoke “free energy.” This can be done with hydrogen taken from water using solar power, for example. This means we could support many times more people –living in harmony with nature- than we have now, EVEN IF WE ARE PREVENTED FROM COLONIZING SPACE”

This should be “even if we can’t figure out how to safely colonizing space.
