In many places, containers with all kinds of pollutants were dumped into the ocean until the 1990s or 2000s; it may even still be practiced in countries with a similar level of development. Containers were also dumped in Somalia after the pirates attacked. There are Greenpeace videos from the 1990s trying to prevent radioactive dumping at sea. The remains of World War II also inhabit the seabed. And many other things.

I just hope that clouds of radioactive iodine don't cross my skies, or something much worse.

Fingers crossed.
