The John J. McCarthy Observatory in New Milford will hold its next Second Saturday Stars event April 11 from 8 to 10 p.m.

The topic of the program at the observatory located behind New Milford High School on Route 7 South will be "The State of the Earth."

In a departure from the usual Second Saturday Stars programs of education and entertainment, this event will serve as a call to action to help protect Earth's biosphere.

The plundering and pollution of the planet and the ultimate threat of climate change will be examined, and the campaign of misinformation about these issues by special interest groups will be explored.
