South Australia is at the forefront of sustainable agriculture this month, with the official opening of a tomato farm in Port Augusta. It's not just any tomato farm. Sundrop Farms is a hydroponic greenhouse facility that doesn't use fossil fuels, groundwater, pesticides or soil. The $200 million, 20-hectare farm doesn't even take up valuable arable land. It's located on arid, degraded land that is too barren for traditional agriculture.
Here's how it works. A solar tower standing 115 metres (377 feet) high with 23,000 mirrors pointed at it provides all the power the farm requires, for heating and cooling. It also powers a desalination plant, which converts seawater into freshwater to keep the plants irrigated.
If it works, there is a lot of "arid, degraded land that is too barren for traditional agriculture" in Nevada and eastern California that could be used the same way.

When the evil locals reclaimed their land from the colonials, and the colonials used every avenue at their disposal to punish them and shut them off the worldwide markets, it was clearly demonstrated that the stupid monkeys were incapable of taking care of that land nearly as well as the good courageous chaps who had left the motherland to help civilize the unworthy.
