Is Earth the ONLY PLANET that has life on it?

We don't know.

As of now, it is.

Will that change?

We don't know.

Until we DO know, then it is imperative that we hold tightly to all the facets that make this planet the ONLY LIVABLE PLANET.

The water, the animals, the ozone layer, the plants, the air, the oceans, the birds, the fish.

They are all essential to the web of life.

We've been dismantling that web piece by piece.
