I do not want to repeat what other said but I do not see this as problem there are deserts in the world, which are not used for food production and they are have not been use for anything else in that sense. Nothing lives there so there is nothing that could be endangered. Total area needed to power entire world with solar would be ~ 532,900 square kilometres (square with sides 730 km) roughly area of Spain. Space of just 3 deserts is: Sahara 9,000,000+ Australian Desert 2,700,000 Arabian Desert 2,330,000 Gobi Desert 1,295,000 Further more, vertical farms are not just about space, correct me if I am wrong but vertical farm use less water and they have a better control of pests without usage of chemicals, they are easier to work with and automate food production.
