It’s estimated that a garbage truck full of clothing is being sent to a landfill every second, with less than 1% recycled into new clothes. One way to stop clothes reaching landfill is reusing, repairing and recycling them. This is part of ‘circular fashion’ - where textiles already in circulation are used again and again, instead of producing new ones. Lots of fashion brands and consumers are trying to make the fashion industry more sustainable. We hear from two projects at the forefront of this. Whitney Speke joins us from Nairobi to tell us how Africa Collect Textiles is tackling clothes waste in Africa. She also shares her views on the 30 wear challenge - which encourages consumers to wear their clothes at least 30 times. We’re joined by Taylor Greene who works for Circ, a US-based company. Circ’s innovative recycling technology is addressing the fashion industry’s carbon footprint – which accounts for around 8% of global carbon emissions. Plus, sustainability journalist Sophie Benson explains how apps have helped make sustainable fashion more accessible, and how it might be scaled up in the future.

Cape Verde has become the first sub-Saharan nation to be declared malaria-free in fifty years. But mosquitoes, the insects that spread the deadly disease, have started to fight back. One type of the insect has adapted to break all the rules and dodge all the measures we’ve brought in to beat them. Unlike most mosquitoes, Anopheles Stephensi, can live in urban environments potentially putting people in cities in Nigeria, Sierra Leone, Kenya, Djibouti, Ghana and more at risk. The BBC’s Tulip Mazumdar explains the symptoms and effects of malaria.

We need precious metals to run green tech but what’s the cost of mining them? Norway has approved commercial-scale deep-sea mining off its shores in the hunt for precious metals which are in high demand for green technologies. However, environmental scientists warn it could be devastating for marine life. Climate reporter Esme Stallard takes us through the controversial plans.One of the metals Norway is looking for is cobalt.

Amazingly, all 379 passengers in the larger plane survived, thanks to a flawless evacuation. But how common are plane crashes, and how can you improve your chances of survival? Geoffrey Thomas, the editor of the website Airline Ratings, explains. Sadly, five died in the smaller aircraft which was on its way to help with rescue efforts following a huge earthquake in Japan on New Year’s Day.
