Mangrove forests are amongst the most productive ecosystems on earth and encompass 136,000 km 2 of the sub-tropical and tropical coastal zones [1,2].Mangroves provide a wide range of ecosystem services [3,4], are vital habitats for terrestrial and marine species [], and exchange sediment and nutrients with other coastal and estuarine ecosystems [6,7]. This browsing is perhaps only a real problem if it continues to get worse. The largest losses are from conversion of mangrove areas to urban and industrial facilities, In large, unnatural quantities these natural materials can be considered a pollutant. Mangroves are referred to as the regulation and breeding hub of the marine ecosystem. Human impacts in the last years have determined the rapid degradation of wide portions of the mangroves of the island, while other remain pristine and were selected for a comparison (Supplementary .

Mangrove forests are among the world's most vulnerable subtropical and tropical habitats. Human Impacts Mangroves are victims of dredging, filling, and diking, water pollution from oil spills and herbicides, and urban development within the state of Florida. In recent years the biggest regional threats to mangroves are the ever-increasing development of the tourism industry, pollution from runoff of fertilizers and pesticides, and improper disposal of wastes. These habitats provide a rich source of food while also offering refuge from predation. At the outset of the 20th century, there was approximately 31 million square miles (50 million square km) of forest around the world. Mangroves also help prevent erosion by stabilizing sediments with their tangled root systems. Significant benefits can also be gained by altering negative environmental forces acting upon mangroves, a form of mangrove management. 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 .

This massive erosion mostly due to wave and current action and vanishing mangrove vegetation is attributable to the long-term impacts of human activities since the late nineteenth century and also human-induced change within watersheds (dam construction that has reduced the sediment supply to the shore). The major threats to mangrove forests include population explosion, conversion to aquaculture ponds, clear-felling for timber, charcoal and wood chip production for industrial and urban development. However, there is little data available on this. Why are swamps the most valuable ecosystem on Earth? Their dense roots help bind and build soils.
