Climate change: Why planting more trees won't save us

Globally only 9% of all plastic waste is recycled. But why are mechanical recycling rates so low? And could chemical recycling help achieve our targets or is this the wrong approach to the plastic waste problem?

Substituting fossil-based plastics with compostable ones could help address plastic pollution. But not all bioplastics are eco-friendly or biodegradable. A startup from the UK says seaweed is the answer.

Each year, millions of tons of plastic waste ends up in the environment where it can last for centuries. But the discovery of plastic-gobbling enzymes has raised hopes of solving this mounting problem. Some scientists have called these tiny plastic eaters a game changer. But is this really a scalable solution? And does it make economic sense?

Microplastics have been found everywhere — from the deepest parts of the ocean to the heights of Mount Everest. A problem that is set to intensify as we produce over 400 million tons of new plastics every year. But just how dangerous are microplastics? And what can we do about them?

Each year, the world produces 430 million tons of plastics – and that figure is set to triple by 2060. How did plastics become such a big part of our lives? And what needs to be done to limit their environmental impact?

Global plastics production has doubled over the past two decades. Despite rising consumer awareness, there is more single-use plastic waste than ever before. Pollutive plastic waste is set to triple by 2060. Microplastics are in our food and water and even entering our bodies. How did we get here and what can we do about it? This series launches in June.

By 2050, half the world's population could be affected by at least one allergy. Is global warming to blame? Find out more about rising pollen levels and one of the most allergenic plants in the world that is now also spreading in Germany. (This episode has been republished and updated).

Global demand for meat is growing, but animal agriculture has a significant carbon footprint. Could cultivating steaks, nuggets and sushi in a lab be a solution? (This episode has been republished and updated).

Climate fiction has become a significant cultural phenomenon, reflecting the urgency of the climate crisis and the need for creative responses to this global challenge. But how does it affect the consumer and is it doing more harm than good?

Cli-fi is growing increasingly popular as the climate crisis deepens. But could this mainly dystopian genre play a constructive role in tackling the challenge of global warming?
