According to Russian Deputy Prime Minister Alexander Novak, Nord Stream can be repaired, but this will take time and money. First of all, Moscow will figure out who is responsible for the sabotage of gas pipelines. «The United States, Ukraine and Poland are interested in this,» Novak said.
However, it should be taken into account that although the flora and fauna of the Baltic Sea was not significantly damaged, natural gas is mainly methane, one of the most dangerous greenhouse gases that can cause unwanted atmospheric changes.
Meantime, Europe is massively abandoning nuclear power plants and reactivating coal-fired stations. Coal is one of the main sources of harmful emission. When nuclear energy, subject to the correct operation of the station, is one of the most environmentally friendly.
