Algae -Threat or opportunity ?

Officers paid to talk about big problems have been stopping us from using lakes (and many other areas) for recreation for years
When you next hear someone worried about an environment issue ask them-- is a threat or an opportunity? .
For too long now we hear people being paid to worry us about the threats , when many of us as applied environmental scientists focused on solutions ( http://designwithnature.blogspot.com).
Many of the algal blooms in recreational lakes can and should be managed, not left, like the greens suggest, in a 'no touch zone" .
Algae will form part of our energy future when Departments employ scientists and not narrow focused problem driven project managers.
