... The problem with growing crops in Lesotho is that it is hard to get all these things in the right measures. The harsh and extreme seasons mean that there is either too much sun or too much rain and for too long at a time. These conditions also have had a negative impact on the quality of soil, which ...

Eutrophication
Eutrophication (Greek: eutrophia—healthy, adequate nutrition, development; German: Eutrophie) or more precisely hypertrophication, is the ecosystem's response to the addition of artificial or natural substances, mainly phosphates, through detergents, fertilizers, or sewage, to an aquatic system. One example is the ""bloom"" or great increase of phytoplankton in a water body as a response to increased levels of nutrients. Negative environmental effects include hypoxia, the depletion of oxygen in the water, which may cause death to aquatic animals.
