Sometimes the simplest solutions can be the best solutions. A new filtration system which is “unbelievably simple” could massively address the problem of contamination of our seas and oceans. It has already proven itself to be efficient by preventing large amounts of rubbish from entering the waters around Australia. Simply placing a net on the outlet of the drainage pipes that carry water from residential areas into the sea, traps large amounts of debris that would otherwise pollute the environment. Authorities from the Australian city of Kwinana were the first to install the new system, and it has been extremely effective. Hundreds of kilos of garbage have been extracted every week in just this one small city. Several other municipalities are planning to install the system in the near future.
