e. Human activities affect marine life and marine habitats through overfishing, habitat loss, the introduction of invasive species, ocean pollution, ocean acidification and ocean warming. These impact marine ecosystems and food webs and may result in consequences as yet unrecognised for the biodiversity and continuation of marine life forms.
African environmental problems are problems caused by the direct and indirect human impacts on the natural environment and affect humans and nearly all forms of life in Africa. Issues include deforestation, soil degradation, air pollution, water pollution, coastal erosion, garbage pollution, climate change, Oil spills, Biodiversity loss, and ...

Climate change in Africa is an increasingly serious threat as Africa is among the most vulnerable continents to the effects of climate change. [1][2][3] Some sources even classify Africa as "the most vulnerable continent on Earth". [4][5] Climate change and climate variability will likely reduce agricultural production, food security and water ...
