We all know that in the seas there are huge amounts of garbage in the form of plastic bottles, and all kinds of items. There are thousands of tons of waste that somehow should be removed as soon as possible and in the most efficient way possible. This pollution impoverishes our seas and everything they harbor.
Among several others, there is an organization called Ocean Cleanup Project that has taken action on the matter and has designed a physical system to remove that garbage that accumulates in the sea (starting with the Pacific) and also to sensitize fishermen to collaborate in keeping clean the area where the fish they capture are bred
The following photo shows the map of the area to be cleaned in its different phases.

The system they have designed to collect garbage is like a simple, elongated net that moves from a ship across the surface of the sea and collects the waste that is in it. It is simple to operate and can collect several tons of garbage at a time.
That garbage is deposited on the ship and the net can be thrown back into the sea to continue removing garbage from it.

The garbage collection system is 800 meters long and they will move it through areas of the Pacific at a speed of 1.5 knots.
In the tests they have carried out, 9,000 kg of garbage have been collected in just 12 days, and in some cases they collected more than 4,000 kg in a single day. Which indicates that if there is true will, the garbage of our seas can be almost completely eliminated.
