Collect the ocean garbage 

In the previous journals, it had been mentioned about the ocean garbage is harmful for the sea life. Before this method, it is hard for the people to collect the ocean rubbish in a large scale. The main reason is that the large scale collection maybe cost too much and the fish will be also killed during the process.

This new method is called "floating bin".The bins can be left running 24 hours a day and are simple to empty, It will floating on the water and near the sea level. The bin will suck the rubbish nearby and remain in to the bins. It become a filter of the sea to clean the ocean. Not just the solid wastes, but also the oil of the sea surface can be cleaned The other important things is the production cost of this bins is low. It just cost $3,825 (£2,500) each .

The cost always be the main problem for the cleaning the environment. If the cost of this method is not high and less harm to the environment, it should be promote to the public use.
