challenges to sustainability of the 4 spheres
the 4 spheres:
1: lithosphere
2: atmosphere
3: hydrosphere
4: biosphere
1: population
2: food
3: water
4: energy
lithosphere
solid earth
atmosphere
the gasses that surround the earth (its air)
hydrosphere
all the water found on, under and over the surface of the earth
biosphere
all life on earth
population
population growth>demand growth
food
demand for food> major land use (puts significant pressure on natural ecosystems and their biodiversity)
water
demand for clean water
energy
demand for adequate energy
