"The green-blue blooms of toxic algae have been found in Central Park, Morningside Park and Prospect Park."
"The green sludge appeared in New Jersey’s largest lake in June, ruining a usually bustling season of lakeside leisure.
Then in July, it surfaced across lakes in the Pacific Northwest and along the entire Mississippi seacoast, forcing the closure of the state’s beaches.
Now, the green-blue blooms of toxic algae have been found in lakes and ponds in three New York City parks, leading environmental officials to warn residents to keep pets and young children away from the affected water until the blooms clear."
