Sustaining Aquatic Biodiversity and Ecosystem Services
aquatic vs. terrestrial biodiversity
much of the damages of the oceans are not visible by the people.
people view the seas as an inexhaustible resource that can be absorb an almost infinite amount of waste and pollution while still producing seafood.
The human ecological footprint and fish print are expanding rapidly so rapidly that it is difficult to monitor
how can we protect and sustain marine biodiversity?
managing fisheries, maximum number of individuals that can be harvested annually from fishing or shellfish stocks without using a population drop
governments around the world give more that $30 billion per year in subsides to fishers to help them keep their business running
establishing marine sanctuaries and reserves to establish a global system of marine protected areas.
sustainable consumption, reduce the food waste 45% of all edible seafood ends in the trash.
passing and enforcing laws and treaties, although it is hard to get all nations to comply with agreements laws should be enforced to see results in our environment.
recharging groundwater aquifers
supplying valuable products
sustaining stream flows
reducing flooding and erosion
threats to inland wetlands
rising sea levels
mining for minerals, oil and gases
subsidence or sinking of wetlands due to upriver damaging
draining and filling in for agricultural or urban development or for eliminating the breeding grounds of insects like mosquitos
protecting freshwater lakes, rivers and fisheries
subsides to sustainable practices not unsustainable practices
remove the threats
reintroduce key species
protect from disruption while ecosystem recovers
identify the threats to the ecosystem
laws such as no polluting, no altering of river banks, no damaging
sustainable management of fresh waters fisheries
protect fish habitats
prevent or reduce inputs of plant nutrients that cause eutrophication
ensure a healthy and diverse habitat to control predator and diseases.
remove damns to prevent sediment buildup or water shortage
protect populations from harmful invasive species
prevent overfishing by regulating the time and length of the fishing season
support populations by building reservoirs and ponds and stock them with fish
