The anthropogenic nature of environmental problems with   examples from the SA context.

1. Ozone depletion leading to climate change.

The ozone layer is a layer that protects people from the sun's Ultra violet light but it is now depleting due to Styrofoam and air-conditioning, resulting in climate change. For example, South African wind patterns have been altered as a result of ozone depletion, causing high temperatures.

2.Destruction of natural habitats.

Because of population increase and overuse of natural resources, forests, wetlands and oceans are on the verge of extinction, and many animals are in great danger. In South Africa destruction of natural habitats is caused by mining, expansion of urban areas and the transformation of land to agriculture and this has caused SA to lose some of it's important species.

3.Adverse effects on marine life.

Modern industrial fishing has exploited fishing, putting biodiversity at risk. Furthermore, these industries pollute the oceans, causing fish to die. For example, Seals, coastal birds, and large fish are in danger of extinction because of illegal and over fishing in South Africa, especially in the western cape.

4.The decline in fresh water.

Over use of water, pollution, floods water wastage causes a huge decline of fresh water all over the world. However, according to Water wise, water scarcity in South Africa is caused by pollution and the destruction of river catchments which is caused by urbanization, mining and deforestation.
