Water is a vital source of life for the planet Earth, not only to perform the necessary
metabolic cycle but also to run and regulate all the functions of day-to-day life. Stable
economic growth and development for every nation or country are powered by water,
as its availability impacts agriculture, manufacturing, environment, sustainable devel-
opment, etc. The availability of water directly linked to the amount of precipitation,
which is well-taken care by the hydrological cycle. The changing climate followed
by enhanced levels of temperature leads to disturbance in this cycle. The observation
of the world’s wetland day on February 2 every year highlights the signiﬁcance of wet-
lands as ecosystems. This observance began in 1971 when the Ramsar convention was
convened at Ramsar in Iran. Wetlands play a substantial role in pollution control and
detoxiﬁcation. Because of their exceptional performance as the ﬁlters, the absorption
of pesticides and chemicals, and removing harmful waste from the water, they are
given the Earth’s kidneys’status. Nature plans its natural systems to enhance or
even replace historically gray infrastructure functionalities (WBCSD, 2017). Wetlands
cover around 6% of shares in the global surface they play a unique role in the biogeo-
chemical and water cycle. They are home to a large part of global biodiversityd
tremendous pressure on the ecosystem in the form of land reclamation, extreme exploi-
tation of the resources. Alteration in hydrology, pollution threats are accruing from
many sources on the wetlands on almost every continent.
Further stress to wetlands is expected by climate models, primarily due to changes
in hydrology, rising temperatures, and increasing sea level (Junk et al., 2013).
Twentieth-century climate data show that the United States is in a wetter, warmer
climate pattern. Even other climate forecasts indicate that over the next 100 years,
this phenomenon will continue and potentially worsen. Wetlands are likely to be
affected by the rising sea level trend because of elevated carbon dioxide levels.
