The… • With buildings come people, traffic, garbage, and noise, each of which takes its toll on the plants and animals that inhabit rich coastal ecosystems. The average Asian intensive shrimp farm survives only two to five years before pollution and disease force it to shut down. Most mangroves grow on public land, only about 1 percent of which receives any sort of protection. Mangroves are a type of coastal or estuarine wetland, characterized by the presence of salt ... One of the largest mangrove forests in the world is found on the southwest coast of Florida. Even where some legal designation or protection is in place, preserving mangroves is difficult because of development in the form of: By far the greatest threat to the world's mangrove forests is the rapidly expanding shrimp aquaculture industry. These water diversions alter the natural flow of water that maintains the health of surrounding mangroves as well as ecosystems farther inland and offshore. Climate change is causing two important impacts along the world’s coastlines. • Mangroves are affected by sea level rise, but impacts could be mediated by landward migration in some regions. Draining of wetlands to make space for agriculture or construction work is one of the biggest threats to such areas. This chemical soup, along with enormous quantities of organic waste, contaminate surrounding freshwater and coastal waters. Yet we continue to cut them down unaware at times of the role these trees are playing within the coastal ecosystem. The Museum is open! Mangrove forests are among the most threatened habitats in the world, and mangrove loss is rampant across the globe. As Polidoro et al. Ironically, during this same period, mangroves have disappeared with alarming speed. In the Florida Keys, human development is the greatest threat to mangrove communities. The chemicals enter the food chain and can harm nearby species. Trapping for the caged bird trade is the biggest threat to this bird. The social costs of shrimp aquaculture are also high. Many thousands of acres of mangrove forest have been destroyed to make way for rice paddies, rubber trees, palm oil plantations, and other forms of agriculture. The developments are often associated with increased levels of pollution as well, including solid waste, pesticides, thermal, biological (invasive species), brine, and oil. And in the areas where replanting is attempted, it is often done with seeds from elsewhere, and often done with one species, rather than the mix of species that originally existed. Diverting water can harm mangroves by preventing their seeds from being dispersed via seawater, and it can kill the trees by cutting off freshwater supplies. In places where fishing has declined below subsistence levels, many people have turned to charcoal production for their livelihood, which furthers the cycle of habitat loss and fishery decline. Deforestation for fuel & timber accounts for the ongoing loss of approximately 26 percent of existing mangroves (Valiela et al. Thailand has lost 84 percent of its mangroves, the highest rate of mangrove loss of any nation, while the Ivory Coast, Guinea-Bissau, Tanzania, Mexico, Panama, Malaysia, Myanmar, Pakistan, and the Philippines have each lost more than 60 percent of their mangrove forests. Farmers often use fertilizers and chemicals, and runoff containing these pollutants makes its way into water supplies. Shrimp farm activity alone has been responsible for the loss of 38 percent of the world’s healthy mangroves; the percent climbs to 52 if all agricultural activities are counted (Ellison 2008). Communities around the world are learning how to protect mangroves and use them in sustainable ways. The loss of mangroves as a unique habitat would directly jeopardize more than a billion of the world’s human population. One of the biggest threats to the world’s mangrove forests is pollution. Unfortunately, irresponsible tourism can destroy the very resources people are coming to see. Every year, seemingly “worthless” mangrove forests were cleared to make way for shrimp ponds. The Mangrove forests face some of the biggest threats from climate change and global warming; rising ocean waters; industrial and agricultural waste trough down by rivers etc.They have a number of benefits such as preventing from tsunamis, soil erosion, providing livelihood, etc.Read this informative article to know more Shrimp aquaculture has been the single biggest driver of mangrove destruction, particularly in Southeast Asia. The intensive mariculture operations are most often constructed for export. Reserve your timed-entry tickets. A world without mangroves means a world without most fisheries, without bioshields from storms, and without many bird and other species. We’ve cleared mangrove forests and wetlands to make way for resorts, harbors, roads, city expansion, and industry -- losing all the benefits they provide to both humans and wildlif… The most visible and delicate ecosystem of Karachi, a city with a profound coastal environment, is that of the mangrove forests that thrive in the mingled salt and freshwater where the Indus River meets the Arabian Sea.
