5.7 Protecting Aquatic Biodiversity & Ecosystem Services
How to Protect Marine Biodiversity
Restoration vs Protection
Protection would seek to address the issues afflicting the ecosystem, while restoration could regenerate an ecosystem but the same lingering issue would wipe it out again.
Restoration is not as easy and as successful as protection.
Restoration is more expensive and has a lower success rate.
Subsidies promote overfishing of targeted fish stocks, and causes economic loss. Not a wise investment.
Laws, sanctuaries, managing fisheries, subsidies, sustainable consumption
Hard to enforce or follow certain treaties since ocean is seen as an open-resource, leading to the tragedy of the commons
Priorities for an ecosystem approach to protection and sustenance
Create marine reserves
map and inventory
identify and preserve aquatic hotspots
Raise incomes of people who live on or near protected waters so they become partners in protection
Harder to Protect
Ocean is seen as an inexhaustible resource
Eco footprint/fishprint are expanding too fast to track
most dmg not visible to people
Wetlands (Freshwater Habitats)
Reduce flooding and erosion, filter wastes and poollutants, sustain stream flows in dry periods, carbon sink.
Same way to protect wetlands as marine systems.
Oil spills, draining for agricultural and urban development, and rising sea levels damage wetlands.
