At the global level, climate change will contribute to the disruption of the Earth's natural ecosystems, which could lead to the extinction of wild animal species and plants. It is mainly the impact of climate change on habitat and ecosystems that will dictate the impacts on biodiversity (by expanding them or the opposite).
Climate change will profoundly affect agricultural and forestry production. The effects in terms of production potential will be very variable depending on the regions and plant cover. They can result in an overall tendency for moderate stimulation in temperate climates and for limited warming at 2 ° -3 ° C.
<u>answer:</u> natural selection
