If you sailed the whole of Africa's 18, 950 mile coastline, you would visit 33 countries. Because the ocean has no boundaries, nothing can be done without consequences for the whole. The ocean can seem like a useful bin for the huge amount of waste produced by humankind, but this is not true. Pollution is building up, as oil, plastic and sewage are dumped from boats, cities and factories. On our blue planet, it can seem as though the bounty of the oceans is endless, but over-fishing and by-catch are also threatening marine resources.

The challenges of urban living include getting enough clean water, fresh food and sustainable energy whilst finding safe and efficient ways to deal with the waste produced by millions of people

Soil works hard for us every year, growing our food, but are we giving it what it needs to survive? Without shelter, harsh sunlight bakes the soil, and torrential rains wash it away. Without food - new inputs of organic matter - soil loses its nutrients. We must feed it well for it to feed us well. Fortunately, there are many things people can do to help soil restore and keep its fertility

More than 15 million people across Africa depend on forests for their livelihoods, chopping them down for fuel, or to sell as timber. These short videos show how people in Africa are managing trees and forests for the future, whether for food, income or the environment

Currently, over sixty percent of households in Africa burn biomass fuels, like wood, crop residue, charcoal and dung every day. Of all the biomass fuels, wood is the most sought-after. As the number of trees dwindles rapidly, people have to travel greater distances to collect wood. Women often provide much of the human energy in families and when trees are few and far between, they have to carry heavy loads of fuel wood long distances every day
