It's impossible to say because nature is an infinitely dimensional system, but going by what scientists know:
pros: greenification has massive benefits for biodiversity, biomass, and carbon reduction via tree cover
cons: fennec foxes may go extinct
obviously it will probably have some unpredictable effects on the environment, but that goes for everything. The point is that the benefits are absolutely massive, and also the system is self-regulating (it's very hard to green the desert, it's not like introducing an invasive species)
Thanks for the informative reply.
Is there any benefit to having some desert areas or would the world (minus fennec foxes) be better off if all of the desert became a different biome?
