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.
Discarded car tires littering the streets of Senegal's capital Dakar often become breeding grounds for disease-spreading mosquitoes. If they end up in landfills, their toxic components can break down and seep into waterways. One young entrepreneur, sick of seeing the black tubes polluting her country, decided to give them new life as shoe soles or synthetic turf in playgrounds and courtyards.
