In accordance with the reality that occurs in our lives, we are very dependent on water. Water is a very important element for survival, especially for humans. As in ordinary life, we know that the problems that encompass human life are interrelated. As in the parts of one limb with the other members of the body. Likewise with us who have a connection with nature and whatever is presented by nature, as I said above, one of which is water. But the theme that I want to raise in this post is about the benefits of gravel and rocks for rivers and for people's lives.
