When constructed offshore, the breakwaters create zones of calm water behind them and deposition in this zone of calm ... Due to their high carbon content, fossil fuels contribute to the increase in greenhouse gases by releasing carbon dioxide when burnt. This carbon dioxide traps heat in the earth's atmosphere, warming up the earth. Global carbon emissions have been increasing, from 8.37 billion metric tonnes in 2006...
