This game made me empathize less and less with environmentalists. Forests are an impediment to a transport network. Wildlife are pests. Renewable energy has extremely low ROI.
Solar + storage lowers your pollution and the pests. I wish there were a way to restore the environment like planting trees in order to also remove the pests.
There are mods that will let you plant trees.
Planting trees will reduce pollution, and that in turn will lead to you getting bothered less by biters, the native life forms of the planet.
