Planet versus plastics: the global battle for a cleaner future
Microplastics are pervasive, from Mount Everest to the Marianas Trench, affecting our air, water and health. How should the world respond to the ever-growing impacts of plastic pollution?
In short:
- Over 400 million metric tons of plastic are produced annually, with only about 5% recycled in the U.S., contributing significantly to pollution and climate change.
- Leaders are currently meeting in Ottawa to design a treaty aimed at combating plastic pollution, reflecting the global push for international cooperation.
- Innovative solutions like bioplastics and traditional materials are being considered to replace harmful plastics, promoting a circular economy.
Key quote:
“There are so many things that we can disagree on. But on this one, we all agree … There is no plastic that should be in nature.”
— Erin Simon, vice president of plastic waste and business at the World Wildlife Fund
Why this matters:
The push for a global treaty and the development of sustainable alternatives indicate a critical shift towards reducing plastic waste and its associated risks. Read more: Everything you need to know for the fourth round of global plastic pollution treaty talks.

Climate simulation raises alarm over potential ocean circulation collapse
A recent study by René van Westen showcases how melting Arctic freshwater could disrupt the Atlantic Ocean's circulation, potentially leading to abrupt climate changes.
In short:
- The Atlantic Meridional Overturning Circulation (AMOC), crucial for regulating climate and weather patterns, may be nearing a critical "tipping point" due to increased freshwater from melting ice.
- Historical data and advanced simulations indicate the AMOC has shut down before, with significant global climate implications.
- Recent observations suggest the AMOC is weakening, raising concerns about its stability and the rapid, severe consequences of its potential collapse.
Key quote:
“In simple terms [it] would be a combined food and water security crisis on a global scale.”
— Tim Lenton, climate scientist at the University of Exeter
Why this matters:
Understanding and monitoring the AMOC's stability is vital for predicting future climate changes. A collapse could drastically alter weather patterns, affect global food and water security, and challenge our ability to adapt. Solutions exist but competing interests slow implementation.
