wetlands
Wetlands are known as the lungs of the Earth – and they can be like oases in the concrete jungle of urban areas. They are territories where the ground is soaking wet for at least part of the year. These moist lands give life to healthy ecosystems – acting as natural water filters, preventing erosion, and nurturing a diverse range of plant and animal species. A wetland in a city can also help moderate temperatures nearby and improve air quality. Not too bad for a chunk of mud, is it?
