The idea that plastic will outweigh fish in the ocean by 2050 has become one of the most widely-quoted statistics in environmental discussions. But this disguises the real nature of the problem. Fish make up around 29% of animal biomass on this planet (Ritchie 2024) but calculating their mass in oceans is very difficult. We can estimate algae concentrations from satellite imagery - a proxy for fish food - but actual marine biomass remains uncertain and rather variable. Est

In the United Kingdom, we purchase an estimated 7.7 billion bottles of water every year. This is partially due to the misconception that bottled water is cleaner and healthier than tap water. New technological developments have allowed scientists to detect and count miniscule plastic particles called nanoplastics in bottled water. These particles are absorbed when we drink water from plastic bottles and may impact our health. What are Nanoplastics? Nanoplastics are tiny plas
