Sure but I wouldn't want to try scraping out a living in the Australian outback, would you? Wouldn't be much fun if the UK resembled a dust bowl all year round.You know a lot of places on Earth manage with this weather for 95% of the year without life ending right?
The kinds of plants that manage to eek out an existence in such places are very different to the plants we are used to in our rainy, temperate climate.
And lastly, for a lot of the year such places are barren wastelands, with a short rainy season where the plants return, before doing dormant/setting seed during the dry months.
Frankly we wouldn't be able to deal with that here. The reservoirs are already running dry after two months of hot weather... you think we'd have a hope in hell if there was no rain for another 2-3 months? We'd be screwed.
