Conservation week 6

This week is my last week doing conservation i will be starting meteorology 

In this section of science I learned that only 2.5% of the earth’s water is freshwater. 70%of freshwater is groundwater and 1% is surface water.as fresh water demands increase, groundwater decreases. Pumping groundwater and severe droughts affect the aquifer water levels. Desalination is one process used for distillation. First you evaporate the water which leaves behind the salt and then you condensate it and collect it. Then we talked about irrigation, irrigation is the process of conserving water. Irrigation is the artificial supply to arid and semiarid regions. There are many types of irrigation like the drip irrigation system. Drip irrigation is when water goes through pipes and filters to get the sand out and then goes through different pipes that drip water constantly down at the plants roots
