摘要

Because of climate change, we are at a crossroad with regard to control of harmful algal blooms, and must aggressively tackle the problem before it becomes so difficult that in many ecosystems we are faced with the option of allowing these micro-organisms to go unchecked. Many lakes and estuaries around the world, which provide drinking water for millions of people, and support a myriad of ecosystem services, already have toxic, food web-altering, hypoxia-generating blooms of cyanobacteria. The occurrence is driven by high inputs of nitrogen (N) and phosphorus (P) to the ecosystems from human sources. To reduce the frequency and intensity of noxious and sometimes toxic cyanobacteria blooms, sizable reductions of both N and P are urgently needed. Yet, Climate change will severely affect our ability to control blooms, and in some cases could make it near impossible.
