How much of the Solar System must we leave as a preserve?

The latest to worry the wacko left. Overuse of the Solar System. How soon before the kiddies in school start being driven to protest this activity?

Space Mining Could Ruin Our Solar System If We Don’t Establish Protected Places Now, Researchers Warn.

A study finds that it is in peril of overexploitation:

The study, published April 16 in the journal Acta Astronautica, makes a case for designating 85% of our solar system a protected “wilderness” akin to Earth’s national parks, leaving just one-eighth of eligible planets, moons and asteroids free to be mined or developed by human interests.

According to the study,humans could deplete the solar system of all of its water, iron and other mineable resources in a matter of centuries — potentially leaving the solar system a dried-up wasteland in as little as 500 years.

“Then, we are done,” warn the authors.
