One big impact is the change to food supply. Plants and animals thrive in certain climates (the midwest of the United States for example). Those zones are moving due to climate change. Does that mean they are getting larger or shrinking? Will it require more energy (water, fertilizer, mechanical harvesting) to get the same amount of food? It's my understanding that both land-based and water based sources of food will shrink with a warming planet.
