Air: Changing the Atmosphere
Every year seven million people die from air pollution. It's the world's biggest environmental killer.
Italy is Europe's most polluted country: in 2012, more than 84,000 people in the country died prematurely owing to bad air quality. To combat this, scientists have developed a new type of photocatalytic cement that absorbs pollutants and turns them into harmless salts.
Iceland is the first country in the world to generate 100 percent of its electricity needs from renewable sources, and is taking steps to cut its emissions even further. With the aim of cutting emissions even further, a unique carbon capture system called CarbFix is being pioneered at Hellsheidi geothermal power plant, in western Iceland.

In Denmark, see how a 100%-renewable community on Samso Island is investing in its own green society. In India, a new method of cremation is helping Hindu tradition become more environmentally friendly.
In a busy market in the Ugandan capital of Kampala, a group of women gather to cook. While the dishes they prepare are traditional, the brightly coloured stoves they cook on are new.
The locally made Ugastove, which requires on average half the amount of charcoal of traditional cookers, saves money in reduced fuel costs, cuts carbon emissions and reduces deforestation.
Cheap and versatile, plastic is used for everything. The problem is, it's also indestructible. As a result, it piles up in landfills where it leeches toxic chemicals into soil and groundwater, or ends up in the ocean affecting wildlife and getting into food chains.
Approximately 268,000 tonnes of plastic float in our oceans - that's five trillion individual pieces. If nothing changes, it is estimated that by 2050 there will be more plastic by weight than fish in our oceans.
Death is a messy business. In America alone, 1.6 million tons of cement and over 870,000 gallons of embalming fluid — commonly containing formaldehyde — are buried along with 2.5 million caskets every year.
“What you have here is a landfill … a toxic landfill,” says Glen Ayers of the Green Burial Committee as he looks around a traditional graveyard in Massachusetts.
A look at the state of global food security amid rising concerns about the world population and climate change.
In New Haven, Connecticut, a community of scientists, fishermen and foodies are redefining their relationship with the sea using 3D ocean farming. In Africa, farmer-managed natural regeneration is restoring farmland to improve food security. In Holland, scientists are racing to future proof our planet against our love of meat.
China and the United States are the world's two biggest carbon dioxide emitters, but what approach are these countries' governments taking in the fight against climate change?
In Shenzhen, one of China's most populous cities, new regulations to tackle air pollution are helping to unleash a revolution in clean energy and transport. Stephanie Wong visits Shenzhen to learn more about how the city is cleaning up its transport.
Half the world's population live in cities, and by 2050 the figure will increase to two-thirds, or about 6 billion people. The environmental impact is already extensive. As the global population expands, so too do pollution and pressure on resources.
