Agriculture plays a major role in water contamination. Farming results in the release of large quantities of organic matter, agrochemicals, sediments, and drug residues. The use of fertilizers and excreta at farms cause nitrates and phosphates to enter bodies of water, leading to eutrophication.
Why is water in Africa so unsafe?
Poverty is a huge barrier to access to water and sanitation, and most of the world’s poorest countries are in sub-Saharan Africa. Natural disasters, increased pollution, and a lack of resources are all driving forces of the water crisis in sub-Saharan Africa.

Why does Africa have so many diamonds?
Diamonds in Africa were formed somewhere between 600 million and 3 billion years ago when titanic-force pressure and heat caused carbon 1,200 miles (1,931 km) below the Earth’s surface to crystallize. As recently as a million years ago, erupting molten rock brought the diamonds closer to the Earth’s surface.
