Regarding Protecting Our Nation’s Water and Water Pollution, Open Google Earth and in the search box enter: Bohai Bay, Tianjin,China. Click Search. Zoom out to locate the key rivers entering the bay, then follow them upstream, zooming in to explore the area.

What activities can be seen close to the bay and also upstream that can result in cultural eutrophication?

Explanation / Answer

Looking at the google maps of Bohai Bay, Tianjin, China. The following rivers and the areas they flow through have been noticed.

Most of the regions were agricultural based, hence the human generated eutrophication would be from the pesticides they use in the fields, but near the rivers of Duliulijan and Haihe, existence of a vast industrial sector has contributed to the anthropogenic industrial contribution to the cultural eutrophication. Upstream of Majia river also had a petroleum field that contributed to its composition.

Hope it helps. All the best :)
