The scientists investigated Taihu Lake's water quality before and after taking certain actions. Despite some improvements, the lake is still suffering from eutrophication, a problem from too many nutrients. The researchers found it's crucial to tackle pollution from farm areas to prevent more issues. They studied how fertilizer use and livestock waste affect the lake. Their analysis showed that agricultural pollution plays a big role in the lake's eutrophication. To improve the situation, the scientists suggested methods to manage and reduce pollution from farms in the Lake Taihu region.
