People have been relying for their daily needs and well-being on nature. The natural ecosystem provides varieties of goods and services to us, for instance, fresh water, fisheries, timber, water purification etc. The benefits that people directly get from the natural systems are called ecosystem services (ES).
The natural ecosystem provides both goods and services to us. The ecosystem goods are the things that people produced from soil, water and plants; Crops, Fibre, Timber, Livestock, Tourism, etc. are the example of ecosystem goods. And, at the same time people get a varieties of fundamental and life supporting services such as flood control, clean air and water, pollination of crops and other plants, natural hazard regulation, cultural, spiritual and aesthetic services which are called ES ( Kerr, G., 2010).
Classification of ecosystem services
The united nation was carried out an extensive study of current condition and trends of ecosystem services with the help of 1,300 experts from around the world and prepared the The Millennium Ecosystem Assessment (MEA) Report in 2005. This report classifies ecosystem services into four types. 1) Supporting services: It is a fundamental unit of ecosystem services which support other ecosystem services. The soil formation, photosynthesis, nutrient cycling and water cycling are the supporting service in ES. 2) Provisioning services: These include the goods or products obtained from ecosystem such as foods (crops, livestock, fisheries, aquaculture, and wild foods), Fibre (timber, cotton, silk, wood fuel, genetic resources, biochemical, natural ...

...then the decision. The decision maker should know the consequences of their decision in ES, for example how timber supply, making dam and extensive land use for agriculture affect in ES. The decision maker action may change the ES, they should consider the trade-offs among many option at decision making time and should chose the policies that help to foster and sustain the ES (Ranganathan, J. et al., 2008).
The benefits that we get from the nature are ES and it is indispensable for our overall development and prosperity.

- According to Mooney and Ehrlich (1997), the idea that human beings depend on natural systems traces back as far as Plato. Plato (c. 400 BC) realised that deforestation could lead to soil erosion and the drying of springs (Daily 2007; Gómez-Baggethun et al., 2009). The first modern publication that addresses this concept is in the book Man and Nature written by George Perkins Marsh dated 1864. Marsh started to realize that the world’s resources were not infinite and that natural systems are important to water, soil, climate, the disposal of waste and pest control....

- Mapping Ecosystem Services in Colombia’s Putumayo Region to Inform a Compensation Scheme to Establish Silvopastoral Systems Key Message The rain and cloud forests of Colombia’s Upper Putumayo region are becoming increasingly exposed to agriculture, ranching, and infrastructure development. These activities can have adverse effects on water supply and quality, soil erosion, carbon capture and sequestration, and biodiversity. The additional impacts from climate change intensify these effects and can have serious consequences for future ecosystem services supply, development and livelihoods.... [tags: Environmental Issues]

- Forest ecosystems services emerge and replace timber as a focus point of forest management. Eftec (2005) defines forest ecosystems service as benefits from forest to support human life through such natural processes, for example, in regulating air, water, and nutrient cycles, stabilizing microclimate, and preventing droughts and floods. This approach then emphasize on how to maintain all natural processes within the forest to sustain their natural product such as water, fresh air, and fruits, instead of focusing on sustaining the products itself, especially on timber....

- All biological lives need a supply of external energy. Most Plants are capable of photosynthesis, some bacteria employ natural sources of chemical energy. Many other organisms require different types of energy to grow. Beyond this biological need of humanity, technologically advance societies have increasingly weaken in their dependence on external energy for production of many manufactured goods. Where this technological advancement is a wonderful convenience of modern life in particular, there it allows people to live under a diverse condition of climate, in general.... [tags: Ecology ]

- Growing up near the Chesapeake Bay, I was bombarded with guest speakers since elementary school about protecting the environment. I knew what an ecosystem was by fifth grade, and in seventh grade our class went on a class trip to Smith Island and Port Isabel in the Chesapeake Bay for more intensive education about how humans are connected to ecosystems. Water and ecosystems are important to public health all over the globe, as water touches all of our lives. And when this water is contaminated by oil, many global health issues are caused, but these problems to health may be worth the profits gained from oil.... [tags: Environmental Issues]

- An ecosystem refers to dynamic communities of living (abiotic) organisms like animals, fungi plants or bacteria that interact with each other and share the environment with non-living (abiotic) factors like water, soil, oxygen, sunlight etc. These abiotic factors allow life to happen in the ecosystem. All life depends on non-living or abiotic factors to survive, however the non-living factors can exist without them. Ecosystems vary hugely in size as it can be an entire rain forest with thousands of species or a puddle containing water, algae bacteria and other microorganisms....

- 1. Introduction Wetland ecosystem is one of the most productive ecosystems on this planet delivering massive goods and services to human society. However, due to poor awareness of their values and underestimation of their contribution, many wetlands have been converted to farmland or urban areas, or influenced by pollution due to agricultural and industrial activities. Consequentially wetland ecosystems have severely declined and degraded globally during the past decades. In order to restore and protect wetlands, hence ensure a sustainable supply of wetland goods and services, it is important to recognize their values.... [tags: Environment, Sustainable Development]

- The tremendous impact that oceans have on our planet engender how we live our lives on this earth. In this aspect we can agree that our lives depend on oceans and their many contributions to the earths environmental services. Incidentally, oceans take up more than two thirds of the total world; other than giving us a form of outdoor recreation from our daily stressful lives it's an immense structure that makes our regal earth blue. By the same token, without the oceans we would not be able to breathe, thus suffocating resulting in the earth being an inanimate matter in the solar system....
