Plastics Emissions May Double Health Risks by 2040: Study
A new study says that the bad effects of plastics on our health might get much worse by 2040.
This is because of the gases and chemicals that come from making and burning plastics.
The study looked at how plastics affect our health from the time they are made until they are thrown away.
They found that the biggest problems come from making new plastics and burning plastic waste.
The researchers say we need to make less new plastic and find better ways to deal with plastic waste to protect our health.
Over 175 countries are working on a treaty to deal with this problem.
The study also found that improving plastic waste collection and recycling alone won't have much impact, but combining these improvements with substituting or reusing materials can reduce health impacts linked to plastic emissions.
Health impacts from plastics emissions may double by 2040 compared to 2016 levels if current trends continue.
Global plastics production may not peak until beyond 2100, worsening environmental and health burdens.
The study quantifies health impacts in terms of 'disability-adjusted life-years' related to greenhouse gases, air pollutants, and toxic chemicals.
Primary plastics production and open burning are identified as the greatest sources of health harms.
Researchers recommend reducing primary plastic production and regulating non-essential plastic uses to mitigate health impacts.
