We should all take only the water we need, and no one should destroy it. Most importantly, we should all take care of our water.
Everyone should own the water. No one should own more than someone else, because everyone - people, plant, or animal - needs it.
For example, the Palestinians built a water supply, and Israelis bulldozed it over and it got polluted. In Flint, Michigan, the manager of the water switched the water source just to save money. Pollution damaged the water system, and now a lot of lead is in the water.
In North Dakota, the Sioux tribe should own the land, but the government took it away and now a company wants to build a pipeline that many fear will destroy people's water supply.
