Introduction
An ecosystem is a community of living organisms (plants, animals and microbes) in conjunction with the nonliving components of their environment (things like air, water and mineral soil), interacting as a system.[2] These biotic and abiotic components are regarded as linked together through nutrient cycles and energy flows.[3] As ecosystems are defined by the network of interactions among organisms, and between organisms and their environment,[4] they can be of any size but usually encompass specific, limited spaces[5] (although some scientists say that the entire planet is an ecosystem).[6]
Energy, water, nitrogen and soil minerals are other essential abiotic components of an ecosystem. The energy that flows through ecosystems is obtained primarily from the sun. It generally enters the system through photosynthesis, a process that also captures carbonfrom the atmosphere. By feeding on plants and on one another, animals play an important role in the movement of matter and energy through the system. They also influence the quantity of plant and microbial biomass present. By breaking down dead organic matter,decomposers release carbon back to the atmosphere and facilitate nutrient cycling by converting nutrients stored in dead biomass back to a form that can be readily used by plants and other microbes.[7]
Ecosystems are controlled both by external and internal factors. External factors such as climate, the parent material which forms the soil and topography, control the overall structure of an ecosystem and the way things work within it, but are not themselves influenced by the ecosystem.[8] Other external factors include time and potential biota. Ecosystems are dynamic entities—invariably, they are subject to periodic disturbances and are in the process of recovering from some past disturbance.[9] Ecosystems in similar environments that are located in different parts of the world can have very different

Everything you buy has a product life cycle, or a history of how it was produced using what materials. When possible, reduce the impact of your purchase by buying products that are made locally and/or are manufactured from recycled materials. 4 Eat local, organic food. Local food travels less distance from farm to your table, which means that it has a lower carbon footprint, is fresher, and supports your community 's farmers. Organic food is produced without the use of chemical pesticides or fertilizers, and without genetically modified crops. Chemical pesticides and fertilizers can get into the natural environment and harm existing plants and animals; genetically modified crops reduce biodiversity by encouraging a monoculture farm. 5 Travel wisely to decrease your carbon footprint. Use alternative methods of transportation whenever feasible---walk to the store, ride your bike to work, take public transportation downtown. When you do drive, accelerate and decelerate gradually to conserve gas. Also, make sure that your tires are properly inflated and that the emissions system on your vehicle is well maintained.
