contributing to preserve the Black Sea

The lastest ecological disaster in the Black Sea made me think about the future of this place.
Europe is in front of one of its largest catastrophes - many thousands of liters of dangerous stuff, oil and chemicals poured into the Blak Sea.
Many animal species are condamned. Lots of birds and fishes died.

The main european rivers (Danube and Dniepr) are throwing into the Black Sea and pour a non-negligent quantity of waste.

1. to clean the polluted areas

2. to burden the polluters with higher taxes

3. to preserve the ecosystem (waters, beaches)
