Something most of us are not aware of: An amazing amount of trash is dumped into the ocean. It comes from landfills and from cruise ships that throw their trash directly into the sea. The ocean is becoming more and more acidic, and a surprising amount of debris is being dumped in space too.
Outer space security has become an increasingly important problem recent years, since derelict satellites and parts that “got away” when they were being repaired are orbiting the earth. We need to pass some international laws to avoid collisions with space trash!
