Turkey hosts more than three thousand endemic plant species, has high diversity of other taxa, and is almost entirely covered by three of the world's thirty-five biodiversity hotspots. Although some environmental pressures have been decoupled from economic growth the environment still faces many threats, such as coal and diesel fuel emitting greenhouse gases and deadly fine particulate air pollution. As of 2019 there is no fine particulate limit and coal in Turkey is subsidized. Some say the country is a pollution haven.
