The Coasts of Our World: Ecological, Economic and Social Importance emerged information on the ecological, economic and social importance of the coasts areas around the world. They are defined as regions that range from the continental shelf (to a depth of 200 m), the intertidal areas and adjacent land within 100 km of the coastline. They concluded that these regions have been heavily altered by human activities. In a recent study within the 100 km limit, 72% still is covered by natural ecosystems and 28% have been altered by human activities (urban and croplands). More than 50% of the coastal countries have from 80 to 100% of their total population within 100km of the coastline. This provides information is about how much humans value coastal areas because majority of these areas humans live in these areas. That is why it should be highly important that these communities provide protection and management to keep these areas healthy not just for humans but, the entire ecosystem that depends on it. Unfortunately, majority of these areas have been affected in some way by human activity that has caused serious problems for human health and the environment. So, let’s address environmental and human health impacts of crude oil in costal ecosystems. Oil spill studies: A review of ecological effects gave a general perspective on how crude oil ecologically effects of oil spills. It addressed that oil regularly reaches sediments after a spill; oil in anoxic sediments is persistent;…
