1. Roughly eight million tonnes of plastic enter the ocean every year.

2. Much of it breaks down into microplastics smaller than five millimetres.

3. These particles have now been found in fish, salt, drinking water and human blood.

4. What remains unclear is the precise effect of long-term exposure on human health.

5. Laboratory studies show inflammation in animals, but the doses used are often unrealistically high.

6. Cleaning the ocean is far harder than preventing the waste in the first place.

7. Most researchers therefore argue that regulation of packaging offers the greatest return.
