Lake slime getting worse globally since the '80s
New Zealand isn't the only one suffering from toxic algal blooms in our freshwater, as US researchers found algal blooms in large lakes have been on the rise globally in the past three decades. Using satellite data to monitor surface algal blooms on 71 lakes in 33 countries, they found blooms were more frequent in 70 per cent of the lakes they studied. Strangely, this increase in blooms changes couldn't be linked to usual causes of algal blooms like changes in rainfall or fertiliser but the few lakes that had blooms drop over time warmed less compared to other lakes.
