2. What are ecosystem services? “a wide range of conditions and processes through which natural ecosystems, and the species that are part of them, help sustain and fulfill human life”(Daily et al. 1997:2) Keeping this definition in mind, what are the possible benefits supplied to human societies by natural ecosystems?
10. The regulating and supporting benefits. Purification of air and water Mitigation of droughts and floods Generation and preservation of soils and renewal of their fertility Detoxification and decomposition of wastes Pollination of crops and natural vegetation Dispersal of seeds Cycling and movement of nutrients Control of the vast majority of potential agricultural pests Maintenance of biodiversity Protection of shores by erosion Protection from harmful UV rays Partial stabilization of climate Moderation of weather extremes and their impacts
12. The cultural benefits? Provision of aesthetic beauty and intellectual stimulation that uplift the human spirit Provision of spirituality Provision of spaces that provide opportunities for recreation Also, most if not all human behaviour, whether individual or in groups, is mediated by culture, making anything we engage in (food, shelter, religion…) a cultural act dependant on the goods and services provided by ecosystems.
14. The issue. Regulating and supporting services flowing from natural ecosystems are undervalued by society. Many human-initiated disruptions of ecosystems are difficult or impossible to reverse on a “human relevant” timescale. A continued lack of awareness will dramatically alter the Earth’s remaining natural ecosystems within a few decades.
18. Ecosystem Goods: Aquatic Food In 2006, 6.44 billion people each ate 16.4 kg of fish, for a total consumption of >110 million tonnes (FAO 2008:63) (FAO 2008:62)
19. Ecosystem Goods: Aquatic Food In 2006, fish exports destined for human consumption accounted for only 38% of all production with a value of $85.9 billion US. (FAO 2008:45) (FAO 2008:46)
20. Ecosystem Goods: Aquatic Food 80% of 523 world fish stocks are fully exploited or overexploited [suggesting that] the maximum wild capture fisheries potential from the world’s oceans has been reached. (FAO 2008:34-35) (FAO 2008:33)

Editor's Notes
Provisioning: food, water, and the wealth of materials thatunderpin all life on this earth. These services are perhaps the ones most easily understoodand currently valued the most.Regulating:water filtration and purification, storm protection(barrier islands, wetlands, and reefs, for example), pollination, erosion control, andcarbon sequestration. Although we are learning about these services, our ignorance ofthem and of their enormous economic value remains profound.Cultural: Recreation is the most obvious; but as important arethe spiritual and aesthetic values that many find in nature.Supporting: soil formation, photosynthesis,nutrient cycling, and water cycling. These underlie all of the other services.
Ecosystem goods are traded on the local, regional, national, and international markets and have a quantifiable monetary value.Goods consist of organisms and their parts and products.

Spirituality: Haploporusodorus is found above 52 degrees latitude in Canada and Northwestern Europe. It is a polypore – a stalkless shelf-like fungus with pores on its undersurface. It is white, hoof-shaped, and grows on willow trees in conifer forests. Upon close observation one can easily notice the unique characteristic of H. odorus – its smell. The fruiting bodies have a strong odor of anise, kind of like licorice. This smell is strong and persistent, and dried specimens retain their odor. Native Americans appreciated the smells of plants like sage and sweet grass and used these plants for purification rituals. Because of its strong fragrance and other medicinal properties, Haploporusodorus has been an important fungus in the culture of Northern Plains Indians.Seaweed: face, hand and body creams or lotions; Seaweeds can be used to reduce the nitrogen and phosphorus content of effluents from sewage treatments; remove heavy metals in cleaning up wastewater
This is a chart from the United Nations publication “The State of World Fisheries and Aquaculture” published by the UN Fisheries and Agriculture Organization in 2008 .In 1950, the world captured and cultured 20 million tonnes of aquatic goods for human consumption and other uses.In 2006, this figure has rose to over 140 million tonnes.
Biological diversity, or biodiversity for short, refers to the variety of life forms at all levels of organization, from the molecular to the landscape level. Biodiversity is generated and maintained in natural ecosystems, where organisms encounter a wide variety of living conditions and chance events that shape their evolution inunique ways. Out of convenience or necessity, biodiversity is usually quantified in terms of numbers of species, and this perspective has greatly influencedconservation goals.http://www.planetark.com/dailynewsstory.cfm/newsid/46692/story.htmGolden Rice -- which includes three new genes, including two from daffodil -- is yellowish and contains beta-carotene, a substance that human bodies convert to Vitamin A. International Rice Research Institute says they expectraise yields by 50 percent in the next 10 years.IRRI calculated the world needed to increase the annual rice output by nearly 70 percent to 880 million tonnes by 2025 from 520 million tonnes currently to meet projected global demand.Together with China, IRRI is also working on dry land rice, known as aerobic rice, that can grow on dry soil like wheat."Water for agriculture is becoming more and more scarce as water is diverted for urban use and industrial use," he said.

http://www.mah.gov.on.ca/Page1705.aspxThe Oak Ridges Moraine contains the largest concentration of headwater streams in the Greater Toronto Area. The Moraine acts as a recharge area for groundwater. The Moraine provides a natural habitat for sensitive and threatened plant and animal species not found elsewhere in the Greater Toronto Area. The Greenbelt includes the protected lands of the Oak Ridges Moraine, the Niagara Escarpment, and the headwaters of all major watersheds in the western Greater Toronto Area.Because the moraine is a rich resource of sand and gravel, it has become one of the main sources for the aggregate industry serving the Greater Toronto Area. The Oak Ridges Moraine is more than 90 percent privately owned, with a population of more than 100,000. It crosses 32 municipalities, supplies drinking water to more than 250,000 people, and supports related agricultural, industrial, commercial and recreational uses. In 2001, the Ontario government recognized the need for provincial regulation of the many complex land use issues on the moraine, in order to preserve the health and diversity of its greenspaces.
eight people lived inside a 3.15-acre closed ecosystem for two years (1991-1993). replicas of several ecosystems were constructed – a rainforest, coral reef ocean, desert, forest, intensive agriculture, savannah, marsh. they invested more than $200 million in the design, construction and operation of the model (1987)The eight people were unable to meet their fundamental needs for the 2 year period problems aroseA drop in atmospheric oxygen concentration to 14% (the level normally found at an elevation of 17,500 feet)high spikes in carbon dioxide concentrations, nitrous oxide concentrations high enough to impair the brain,an extremely high level of extinctions 19 of 25 vertebrate species all pollinators which would have ensured the eventual extinction of most of the plant species as well)Overgrowth of aggressive vines and algal mats, and Population explosions of crazy ants, cockroaches, and katydids.the system was not viable and sustainable for either humans or other species
In 2005, the World Resources Institute published a synthesis of their Millenium Ecosystem AssessmentThe report outlines the current state of ecosystems globally and how they have changed in the last 50 years.In 2007, the World Resources Institute published “Restoring Natures Capital: An Action Agenda to Sustain Ecosystem Services”“The Assessment offers public and private sector decision makers a new way of seeingand valuing ecosystems from the perspective of nature’s services. In doing so, theAssessment confronts the status quo in uncomfortable but necessary ways. It forces usto acknowledge what we should have known all along—that ecosystems are a source ofextraordinary wealth and value.”They outline 5 problems and actions to change the predominant view of the value of ecosystem servicesPROBLEM: People fail to make the connection between healthy ecosystems and the attainment of social and economic goals.ACTION: Develop and use information to educate all partiesPROBLEM: Local people lack the rights for use and decision making about ecosystemsACTION: Strengthen the rights of local peoplePROBLEM: Ecosystem services management is fragmented among different agencies that do not communicate ACTION: Create connections between governing bodies to ensure successful managementPROBLEM: Accountability is weak or absentACTION: Create accountability legislation and enforce itPROBLEM: Incentives for responsible management is limited or nonexistentACTION: Align economic benefits with positive stewardship and economic costs with degradation
