註釋Today, more and more freshwater bodies have become polluted by nutrients originating from agricultural, domestic and industrial sources. This situation causes these freshwater bodies to become eutrophied. In an effort to prevent this problem, significant financial resources have been invested in expensive infrastructure and equipment, yet the situation is worsening. Furthermore, there has been a misconception that the only way to prevent the problem is through the use of technology. Technology can assist in this endeavor, but it is not the only answer. The process of eutrophication of lakes and reservoirs is very much related to how society functions. These societal factors are rarely comprehensively addressed, even when experts undertake the diagnosis of existing environmental problems.
