“If there were no mangroves, the sea would have no meaning. It's like having a tree without roots, because mangroves are the roots of the sea..." (AMNH, 2003). Internationally, mangrove communities are recognized as critical in supporting a healthy and diverse ecosystem. However, since the late 1950s, humans have decimated total mangrove forests by a third (Fidenci, 2007). The World Mangrove Atlas states that mangrove decimation is occurring “four times faster” than terrestrial forestation (Cook, 2010). The impacts are numerous, as these “highly productive ecosystems” support the coastal and intertidal areas in which they occur (Hogarth et al., 2007). They are invaluable, capable of withstanding varying levels of salinity and extreme weather conditions, playing a key role in the biological health of coastal aquatic ecosystems and overall diversity (Wetlands International, 2012). They help in the purification of water, ridding it of pollutants and potentially poisonous toxins such as waste and foreign poisons (National Geographic, 2010). Mangrove forests are found within estuaries and intertidal regions, but the vast majority of these are threatened (Polidoro, 2010). The importance of mangroves is prominently demonstrated by various factors, covering environmental, economic and social perspectives. The existence of mangroves is essential to maintaining the environmental health of the ecosystem, extinction or substantial damage to biodiversity organisms occurring to the exclusion of various mangrove species. Mangroves provide housing and nutrients to diverse flora and fauna, vital protection from predators, coastal stabilization and dissipation of wave energy along the coast having an e...... middle of paper ......leads to aquatic environment. This could be reassessed in a year, through a mandatory government investigation. The results can be collected and analyzed to ensure that the approach is working. The research analyzed clearly highlights the benefits and importance of a preserved environment. It is clear that from an environmental, economic and social perspective it is the responsibility of individuals to ensure that mangroves are maintained as the essential ecological systems that they are, allowing them to thrive in the best possible conditions. When analyzing the proposed dredging of Cairns, it is optimal to minimize potential blockages that could occur and claim economic and environmental benefits. In conclusion, it is possible to ecologically sustain healthy mangrove systems, while benefiting from economic and social growth, if limitations and strategies are capitalized on..
