The World Wildlife fund is predicting that the Baltic Sea will suffer unsustainable pressure as conflicting interests compete to use its resources and to pollute it. Sweden is blamed for removing the tax on fertilizers, thus encouraging farmers to use chemicals which can pollute the ecosystem. Other governments are planning to develop wind farms at sea, and freight traffic on the sea is expected to double. They are asking for a co-ordinated strategy to avoid a free-for-all which will harm the Sea in the long term.
