Wetlands: what they are and why they are vital to the ecosystem
Wetlands: what they are and why they are vital to the ecosystem Wetlands are natural or artificial areas, temporarily or permanently flooded, such as marshes, lagoons and peat bogs. These environments provide numerous benefits to the planet, including protection from floods, help in countering drought, water purification and the absorption of CO2. Rich in biodiversity, they are habitats for many species. However, wetlands are among the most threatened ecosystems, having declined dramatically in recent decades because of urbanisation and climate change.

Penguins in danger: their natural food is ‘plundered’ by industrial fishing
Extinction of South African penguins – the only species found across the whole continent – is a serious risk. Their numbers have fallen by more than 99% over the last 120 years. At the current rate of decline (7.9% a year), the species – the only African penguin – is estimated to become extinct in the wild by 2035.
