# Lakes, which cover nearly four-percent of the planet’s land surface, are disappearing at an alarming rate due to pollution, habitat loss, invasive species, and climate change. Today marks World Lake Day, which aims to raise awareness of the importance of lakes and the sustainable management of lakes and related ecosystems. The United Nations Environment Programme warns that by 2050, lakes ecosystem value could drop by 20-percent, pollution could more than double, and methane emissions may surge.
