When it comes to enforcing this, 'Space Law is unclear.' 🤔

co-author Dan Fourie noted that 75 percent of the mercury falling back to Earth will be deposited in the world’s oceans. This could constitute a greater magnitude of mercury than the land-based anthropogenic mercury emissions that are eventually deposited in the oceans.

This is the situation that occurred in Minamata, Japan, in the 1950s, when large amounts of mercury were absorbed into the bay's marine ecosystem. Fish from the bay were eaten by local residents, resulting in the deaths of more than 1,000 people, with many more affected "Health agencies worldwide—including the U.S. Food and Drug Administration and all 50 states—warn pregnant women to avoid or limit consumption of certain fish because of mercury exposure risks, particularly for the pregnant women and the developing fetus," added Bender. The reduction of satellite launch costs is leading to the creation of a new generation of smaller, cheaper satellites for Earth observation and communications.
