Unfortunately, the sea is gradually turning into a huge garbage dump, where all kinds of garbage fall. Such garbage accumulates in the sea or floats to the shores.
Landfill
Many harsh laws prohibit the dumping of garbage and various waste into the sea. Nevertheless, some people pretend that they do not know about it, and dump garbage from dump trucks directly into the sea waves.
They do very badly dropping banana skins, candy wrappers, bottles and cans. The sea is not for them alone, but for all. So nice when it is clean! Each of us must do at least a little so that the waves of the sea are always blue and the foam white.
Sewerage
When water from toilets and bathtubs is drained into the sea without any treatment, billions of pathogenic microbes get there together with it. Waste from factories and factories also flows into the sea, and yet they contain toxic substances!
Oil vessels
If a tanker filled with oil spills it at least a little, this is a big disaster for the sea. Oil spills over the surface of the water with a huge greasy stain, the inhabitants of the sea and algae are poisoned, and seabirds stick together feathers, and they die in thousands.
Rivers
Flowing past villages and cities, the rivers become very dirty, because people throw anything at them. The rivers carry all this garbage to the sea, and therefore, at the mouths of the rivers you can see garbage of all sorts and sizes. Very often swimming in such places is prohibited.
