Coastlines and estuarine environments will always be heavily influenced by human activity. As a matter of fact, over 80% of all marine pollution comes from land-based activities, most of which are industrial or agricultural in nature. From an empirical point of view, sea-based oil drilling and gas transportation are the two biggest causes of coastline contamination, but these antiquated issues are further exacerbated by various inland activities, the most prevalent of which are shown below:
  • Discharge of ammonia and methane into waterways
  • Unremitting use of insecticides, pesticides, and other agricultural chemicals
  • Land-based oil, coal, and natural gas usage
  • Runoff from manure facilities and fertilizer plants
