A region with forest, a river and a city. Click Run to grow the population year by year: demand for timber, land, water and energy rises, so the forest shrinks, the air fills with more emissions, and the river slowly turns dirty — the scene updates instantly with the data. Choose a protection measure (reforestation, wastewater treatment and water saving, or clean energy) and compare two runs to see that human impact on nature can be reversed. Click the forest, river or city on the scene to read an explanation.
