It's a bit like you just said as an introduction, that any broken container containing plastic will obviously come to the surface and float, most likely, and contribute to the already increasing plastic pollution. One issue with plastic is that it's a very nice thing because it's so persistent, but that's also the problem with it. It's something that doesn't degrade. When it floats, the UV light will destroy the molecules a bit and it will start degrading—or we think it's degrading; we don't see it, but it's just changing forms. It's becoming microplastic.
So it's still there. You just don't see it with the naked eye. The smaller it gets, the more it's contributing to other types of damage. Plastic is one of the threats to the planet at the moment. It was such a brilliant invention, but now we're stuck with it. We are finding it in our lungs. It stays there. It's sticking everywhere. It doesn't go away.
For everyone who uses a plastic mug, which I don't, just think about the plastic that gets released after that—
