How are some humans using more than their fair share of water? What is the effect of using water on environmental systems?
Please write a full paragraph and cite evidence.
Answer:
Some humans are using more than their fair share of water and it is having a huge impact on the environment. People tend to let their water run while brushing their teeth or shaving, and those are just two of the major problems. There may also be leakages, which can waste gallons among gallons of water. Wasting water hurts humans, it leaves them with less accessible, usable water. Additionally, wasting too much water can hurt the local environment as it drains too much water away from the natural ecosystem.

California’s San Andres fault is known for its earthquakes. The Pacific plate and North American plate are sliding against each other at this example of a strike-slip fault boundary.
What is Strike-slip fault boundary?Strike-slip faults are the vertical or nearly vertical fractures that occur where the blocks have mostly moved horizontally over each other. If the block opposite an observer, then the fault moves to the right, the slip style is termed right-lateral in this case and if the block moves to the left, the motion is termed left-lateral motion of the block.
The cause of the strike-slip fault earthquakes is due to the movement of the two plates which are against one another and the release of built up strain from these plates. As the larger plates are pushed or pulled in different directions they build up the strain against adjacent plates until it finally fails. The Pacific plate and North American plate sliding against each other is an example of strike-slip fault.
