This was my first thought when reading the article.

> The lunar far side is permanently shielded from the radio signals generated by humans on Earth. During the lunar night, it is also protected from the Sun. These characteristics make it probably the most “radio-quiet” location in the whole solar system as no other planet or moon has a side that permanently faces away from the Earth. It is therefore ideally suited for radio astronomy.

Maybe we need to treat this as a "pristine natural resource" and put some treaties in place now where we agree to limit how much we "pollute" this area with RF signals, before it's too late?
