Sweden's Commission on Marine Environment has warned that the Baltic Sea is in a "critical" condition and in danger of dying unless pollution from the Russian city of St Petersburg is drastically cut.Half of the fish species in theMuch of the city's sewage flows untreated into the Neva, and from there directly into the Baltic. The Baltic is the world's biggest brackish sea - a peculiar mix of sea and lake, salt water and fresh. Its bed is a mix of ridges and troughs that trap pollutants, and starve fish and plant life of oxygen. And because it only has a narrow outlet to the ocean - between Sweden and Denmark - the water takes 25-30 years to refresh itself. 30% of the total water dumped into the Neva river by St Petersburg companies and apartment buildings goes there unfiltered.
conclusion: Too much polution is getting into the baltic while he baltic can onli replenish its waters very slowly.This has a very harmful on the marine live and the environment. If the authorities from the russian city do not take action and stop polluting the baltic with untreated industrial and city watse the pollution will spread on a bigger scale.
