<div style="text-align: justify; "><b style="font-size: 1rem;">Although coastal and freshwater wetlands – such as swamps, mangroves and marshes – contain 40 percent of all plant and animal species, many are polluted or degraded due to climate change and human development.</b><br></div><div style="text-align: justify;"><br></div><div style="text-align: justify;">On World Wetlands Day Thursday, the UN called for urgent action to revive and restore these ecosystems, which are disappearing three times faster than forests.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">Wetlands cover roughly six percent of the Earth's land surface and are vital for human health, food supply, tourism and jobs.&nbsp;</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">More than a billion people worldwide depend on them for their livelihoods, while their shallow waters and abundant plant life support everything from insects to ducks to moose.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">Wetlands also play a crucial role in both achieving sustainable development and the fight against climate change.&nbsp;&nbsp;</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">They provide essential ecosystem services such as water regulation, and reducing the impact of flooding, for example.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">Peatlands, a particular type of vegetated wetland, store twice as much carbon as forests.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">However, over the past 200 years, wetlands have been drained to make way for farmland or infrastructure development, according to the UN Environment Programme (UNEP).</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">Roughly 35 percent of all wetlands globally disappeared between 1970 and 2015, and the rate of loss has been accelerating since the year 2000.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">Depending on the amount of climate-related sea level rise, some 20 to 90 percent of current coastal wetlands could be gone by the end of the century, the UNEP said.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">Wetlands have also suffered more biodiversity loss than other land and marine ecosystems.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">Leticia Carvalho, head of the agency's Marine and Freshwater Branch, urged governments to end policies and subsidies that incentivise deforestation and wetlands degradation, and urgently focus on restoration.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">"At the same time, we must guide and drive investments to protect priority ecosystems, such as peatlands, and encourage the private sector to commit to deforestation and peatland-drainage-free supply chains," she added.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">Recently, governments have been stepping up efforts to protect wetlands.&nbsp;</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">At the UN Biodiversity Conference in December, countries agreed a landmark deal to protect a third of the planet's lands, coastal areas and inland waters by 2030.</div><div style="text-align: justify;"><br></div><div style="text-align: justify;">Action to restore wetlands is gathering momentum around the world.
