What measures can you suggest to reduce human consumption of water? Is the water in your area clean? How are these reservoirs protected from pollution? What are the main types of water movement in the oceans? What is the main reason for these movements in the near-surface water layers?

1. To consume less fresh water, it is better to turn off the tap, do not leave it open and do not use water if you do not really need it.
2. (an appeal to the author of the question: it is not known in which region or city of Russia you live, so I will write about the capital) The water in the Moscow River, in general, is not the best, especially if we talk about Moscow itself: drinking it is certainly undesirable, and if we talk about some settlements where this river flows, we can say that you can swim there, for example, in the Pavshinskaya floodplain and the village of Agafonovo.
3. The heads of the administrative apparatus of power take measures to clean up the river bed and rehabilitate the river. For this, a whole program was created. Its goal is not only to improve and protect the cleanliness of the Moskva River, but also to the citizens in general (creating favorable conditions). In addition, many community organizations also maintain cleanliness.
4. There are several movements:
a) deep currents;
b) ebb and flow;
c) rise of deep waters to the ocean surface;
d) surface currents;
e) naturally, waves.
5. The reasons are the rotation of the earth;
* wind;
* different density of water at different depths.
