Rather, they are the result of our lust for modernization and development. For example, terrestrial runoff (e.g., sedimentation, contaminants, nutrients) has a significant impact on the architecture and function of mangrove root systems that ultimately will lead to a decline on productivity and growth over time. Mangrove roots (pneumatophores) are sensitive to trampling, and the mangrove wildlife, particular breeding birds, are prone to disturbance. 2006, Zhang et al.

The impacts of global climate change such as rising sea-level, altering weather patterns, and acidifying oceans are putting mangrove forests at high risk. Standing water covers the aerial roots, making it impossible for oxygen to reach these specialized roots as well as the underground root systems. Increase in temperature alone seems to have an overall positive effect on mangrove trees. [3], One of the greatest threats to mangrove habitat is human development, which in many regions of the world creeps ever closer these critically sensitive ecosystems.

Coastal management exists to protect environmental resources for both economical and ecological value. Standing water covers the aerial roots, making it impossible for oxygen to reach these specialized roots as well as the underground root systems. In addition, threats from human exploitation pose significant concern for their regeneration and restoration. Conservation International is an active partner in the Global Mangrove Alliance, an organization of technical experts, policy makers and non-governmental organizations dedicated to promoting mangrove conservation and regrowth. Conservation of mangroves is important for the survival of mangrove species, humans and also for the survival of two other habitats – coral reefs and seagrass beds.

Human impacts has cause: Dredging suffocates mangroves when the aerial roots become flooded, preventing oxygen from reaching the root system. One human impact is agriculture. Intense storm events can also have both destructive and constructive impacts on mangrove ecosystems. Matthew Cope 507 views In developing countries, mangroves have proven critical for saving human lives by their dampening of the wave heights and wind speeds during coastal storms. The extent of damage to and recovery of mangroves depends upon the type of oil spilled and the amount reaching the mangroves and remaining after cleanup efforts.

Australia.'' Although section 302 of the Coastal Zone Management Act suggests that “important ecological, cultural, historic, and esthetic values in the coastal zone which are essential to the well-being of all citizens are being irretrievably damaged or lost”, competing demands often sacrifice the intrinsic value of nature for human development. Originally published at ScientificAmerican.com, As the global human population continues to increase, many organisms have had to adapt to the loss and fragmentation of their habitat by development. Not surprisingly, global biodiversity has steadily declined, and as Anthony Barnosky, a Professor of Integrative Biology at UC Berkeley suggests, “we are witnessing a collision of human impacts and climatic changes that caused so many large animal extinctions toward the end of the Pleistocene.” Many of the impacts that ecosystems experience today are not “natural” occurrences. Despite the enthusiasm with which we should, as a society, be tackling the looming problem of mangrove destruction, it seems that human impact is the leading cause of worldwide mangrove loss, instead.
