How should we ensure the safety of our food supply? Water saturation (hydrology) largely determines how the soil develops and the types of plant and animal communities living in and on the soil. Sadly, wetlands are threatened by many human activities. Direct impacts result from disturbances that occur within the wetland. 1997). When one native species start dying off as a result of this competition, the entire food cycle of the ecosystem gets disrupted.

Environmental Pollution Humans, their machines, and their animals release enormous amounts of pollution to the air, water, and soil. Some land management practices have indirect effects, for example, nutrients and sediment can wash from the land into the wetland. In other places where higher temperatures are triggering droughts, the wetlands are also drying out. Their significance, though, is vast.

A dire United Nations report, based on thousands of scientific studies, paints an urgent picture of biodiversity loss and finds that climate change is amplifying the danger to humanity. The disasters seemed to imply that coastal wetlands may serve as protective barriers in the face of hazards, especially in face of climate change (Alongi, 2008; Barbier, 2006, 2011; Barbier et al., 2011; Dahdouh-Guebas et al., 2005; Kates et al., 2006).
