Canada sneezes on New Zealand

Yuck. New Zealand is facing an invasion of Canadian rock snot:

The algae Didymosphenia geminata, commonly called rock snot, has been found in at least a half-dozen key trout fishing rivers on South Island and Biosecurity New Zealand officials began testing rivers in North Island on Friday for signs of infestation.

The algae, which covers rocks and is reported to have originated in Canada, makes waterways look grey and polluted, smothers the insects fish eat and can clump on to fishing lines and lures.

Hopefully New Zealand won't be afflicted next with Canadian boogers like Alan Thicke.
