Both solar power plants and wildlife sanctuaries need a lot of land. We quantify some of the requirements using various estimates of the rate of solar power production as well as the rate of adding wildlife to a sanctuary over the time range 2010-2050. We use population dynamics equations to study the evolution of solar energy and tiger populations up to and beyond 2050.19 pages, 4 tables, 9 figuresPopulations and EvolutionPhysics and Societytext
