The only way Darwinism can be considered zero sum is from a energy perspective - there is no beating the laws of entropy. That perspective is not very useful in the context though, as the darwinian perspective fueled the growth from singular cells living off energy from geotermal vents in the sea to photosynthesis to plants and animals living above ground. This has greatly expanded the amount of resources in the ecosystems and the abilities to use accessible resources.
