The Rhine River

     The Rhine River was used since the roman times and was a very important navigable water way for carrying trade and goods deep inland. It also served as a defensive feature and the basis for regional and international borders. Castles along the river found the river very important because river traffic could be stopped for collecting tolls by the state controlling that portion of the river. The river supplied water to the surrounding soil so the land was very fertile and many farms were built on the river.
America's industrial heartland would be the Rust Belt. The Rust belt begins in south central new York and ends in north Illinois and ester Wisconsin. A while ago it was called the industrial heart of america. But industry has been declining in the region since the mid 20 the century due to many economic factors like the decline in coal and steel industries because of factors like industrialization and globalization.

     The Rhine River is the most polluted river in Europe. People have been dumping waste in it literally since the roman times. Factories that were later built on the river dumped chemicals into the river and that gases and smoke that the factories produced hurt the cultivation process and made the land less fertile. Researchers say the river is almost dead and a lot of the fish in the river has diseases and mutations and are unsafe to eat. 
     There are many ideas on how pollution could be stopped like making it illegal to dump into the river and maybe creating a volunteer team to clean up the area. But these would be difficult to implicate because the river has had so much damage to it it is almost unrecoverable because for so long people has been polluting it and most of the time they did not understand the damage they were doing because they just simply did not have knowledge of pollution and global warming.
