  4. Ecosystem Services • mitigate ocean swells • lessen the impact of storm damage • section off the ocean to create relatively still, brackish water • wetland systems such as lagoons, marshes, estuaries, etc. can survive because of barrier islands • Negative Human Effects • development often causes accelerated soil erosion (meaning ecosystems on the coast lose the protection that the islands provide and can be destroyed) • rising sea levels (due to global warming) are causing the barrier islands to slowly disappear • easily polluted by boating activities: paint, oil, grease, garbage and illegally dumped sewage • sand and contaminated sediments cannot be returned to the beaches and must be disposed of • sediments are dumped in deeper waters, poisoning the marine life Ocean City, MD -- an urbanized barrier island
