In Michigan they switched their water supply to the flint river to save costs. The water had a high percentage of lead in the water, now they have to replace all the lead pipes. Until all of the pipes are replaced they have to use filtered water and bottled water to cook, clean, and bath. In the end it never helped, it made it worse for the city of Flint Michigan. Sometimes by trying to save a little can cost a lot.
The earths contains 5 spheres. The Lithosphere, the biosphere, the cryosphere, the atmosphere, the hydrosphere, and the geosphere. The lithosphere is earths crust. The biosphere is everything that is living on earth. The cryosphere is solid ice on earth. The atmosphere is the gas on earth. The hydrosphere is all the water on earth. Lastly, the geosphere is all the rocks. Those are the list of earths five spheres.
This website helps me understand that water cycle. The process and the components are always the same. It starts with the atmosphere to clouds to Precipitation to run off to Rivers to stream flow to ocean to evaporation and back to atmosphere. That is one example of the water cycle.
By adding Wolfes to the park it changed the ecosystem in a positive way. Deer were destroying the are by clearing out vegetation that was killing trees and plants. Wolfes came and ate and moved the deer population down and out. this caused vegetation to grow plants, and trees. which brought back beavers, that like trees that build dams that helped the vegetation grow with the water build up in the dams. then small rodents came, which increased birds, foxes weasels and bears to feed on and start the cycle of life. Also the growth of vegetation keep the ground around rivers solid to keep water flow up and keep lake areas full.
