Reduce, reuse - and recycle.
The last of the "three Rs," recycling gives fresh value to the natural resources that are tapped to produce products for consumption. Recycling can benefit the environment by reducing waste - and it's also big business.
As our environment changes, we can change with it. From transforming plastic waste into stylish paving stones in Ghana, to balancing a booming lithium industry with environmental protection in Chile to tackling the problem of food waste in Berlin. Plus, could warmer temperatures lead to the birth of a British wine industry?
Ghana has a huge plastic waste problem — it produces up to 22,000 tons every year, but recycles very little of that. Now, one local company is taking up the fight against the rising tide of plastic by transforming it into paving tiles. This not only helps the environment, but also allows locals to earn a decent wage — and the plastic pavers are now a common sight in the neighborhoods of Accra.
