# Are Planets with mainly one climate Biome Plausible? [duplicate]

So i'll start by saying it feels like a somewhat stupid question in the sense that the answer is no, but im wondering if (for back story of races in a story) its realistically possible for a planet to just be majority or entirely one type of biome, i.e. desert, rain forest, wooded, snowy. it feels like no to me mainly because you end up with different climates due to the curvature of a planet and the distribution of warmth from a star. maybe the desert planet is constantly day time due to having multiple stars in its system, snowy i think is easy to justify, but rain-forest not sure honestly. So please do tear this thinking apart :)

• I don't think the hard-science tag is practical here. We have exactly one example of a planet with life to go on (Earth). We don't have equations for life, much less for biodiversity. We can barely climate model with simulations outside of Earth and Earth climate models are very, very specialized. I don't see a way to produce useful hard science answers. – StephenG Dec 31 '18 at 22:51
