Human activity is causing widespread changes to the oceans’ physical, chemical and biological systems. The major driving forces of change in the ocean are to be found outside the marine environment. Just as most of the major drivers of anthropogenic climate change are land-based, the main drivers of increased pressures on marine biodiversity and marine environmental quality also come from activities on the land. They include the demand for food for human populations, international trade in products from agriculture, and industries and coastal degradation (Ref: WOA Summary, page 39). Drivers in the industrial sector come from industries as agriculture, oil and mineral exploitation, shipping and aquaculture. The push for profitability and low production contribute to pollution and contamination (Ref: WOA Summary, pages 26 to 32, describing these drivers and their impacts on marine biodiversity).
