The problem
Plastic is in our blood, our food and our weather
It is cheap, useful and nearly indestructible. That is the problem. Here is what the strongest evidence says about plastic’s effects on people, animals, the climate and the economy, with every study linked.
Eight things the evidence is clear about
We grade every study for strength. High means large, replicated or systematic evidence. Medium means one good study. Low means small or preliminary. Contested means it is disputed or has not been replicated, and we say why. Statistics that are popular but wrong (the ‘credit card a week’, ‘more plastic than fish by 2050’) are not on this site.

Human health
It is inside us
Micro- and nanoplastics have been found in human blood, placentas, lungs, breast milk and arterial plaque. The largest health study so far, of 257 patients having artery surgery, found plastics in the plaque of 58% of them. Over the following three years, those patients were 4.5 times more likely to have a heart attack or stroke, or to die, than patients without plastic in their plaque. The study shows a link, not proof that plastic caused it. The chemicals that make plastic flexible or hard, such as phthalates and bisphenols, are linked to hormone disruption, fertility problems and heart disease.

Black plastic is a particular worry
Some black plastic is made from old televisions and computers, and it can bring their flame retardants with it. A 2024 US study found these chemicals, including one the US has banned, in black kitchen utensils and a sushi tray. Its risk estimate for a single utensil was later corrected down, but heat does move these chemicals into food: a UK study found a fifth of them went into hot cooking oil. Black trays can’t be sorted for recycling either, so they go to landfill. Cook with wood or steel, and tip ready meals onto a plate before you heat them.

Climate
Plastic is a fossil-fuel product
Around 99% of plastic is made from oil, gas and coal. Making it, and burning it as waste, released about 2.2 billion tonnes of greenhouse gases in 2019, more than the aviation industry. On current growth, by 2050 plastics could use up to a third of all the greenhouse gases the world can still release if warming is to stay within 1.5 °C.
