Is it true that there’s a solid island of plastic in the ocean, visible from space?

This claim is certainly false. The claim of “plastic islands” in the ocean which are the size of countries or even continents is false. There’s no doubt that plastic pollutes the oceans, just as it does rivers, lakes, the soil and the air. However, plastic on the ocean surface is not concentrated enough to form big islands. Plastic accumulation zones on the sea surface are also not easily visible from space. Advanced satellite data and machine learning can help scientists identify areas of elevated plastic pollution.
