Green buildings Global warming problem has become the focus of world attention. In recent years, the greenhouse effect has made a heavy global climate change and has seriously developed many illnesses and changes to our environment.
Used vegetable oil Wood Digestion of organic material to produce methane is becoming an increasingly popular method of biomass energy production. Materials such as waste sludge can be digested to release methane gas that can then be burnt to produce electricity. Methane gas is also a natural by-product of landfills, full of decomposing waste, and can be harnessed here to produce electricity as well.
The advantage in burning methane gas is that is prevents the methane from being released into the atmosphere, exacerbating the greenhouse effect.
Although this method of biomass energy production is typically large scale done in landfillsit can be done on a smaller individual or community scale as well. Environmental impacts of industrial agriculture[ edit ] Industrial agricultural production is highly resource and energy intensive.
Industrial agriculture systems typically require heavy irrigationextensive pesticide and fertilizer applicationintensive tillageconcentrated monoculture production, and other continual inputs.
Substantial climate-disrupting carbon emissionsboosted by the transport of food over long distances, are of growing concern as the world faces such global crisis as natural resource depletion, peak oil and climate Green building essays.
Buying food from local farmers reduces carbon outputcaused by long-distance food transport, and stimulates the local Green building essays.
These vegetables and fruits are also grown and harvested within their suitable growing season. Thus, seasonal food farming does not require energy intensive greenhouse production, extensive irrigation, plastic packaging and long-distance transport from importing non-regional foods, and other environmental stressors.
Local produce also contains less to no chemical residues from applications required for long-distance shipping and handling. As well as promoting localization of food, farmers markets are a central gathering place for community interaction.
A CSA consists of a community of growers and consumers who pledge to support a farming operation while equally sharing the risks and benefits of food production. CSA's usually involve a system of weekly pick-ups of locally farmed vegetables and fruits, sometimes including dairy products, meat and special food items such as baked goods.
Local food production ensures food security if potential transportation disruptions and climatic, economical, and sociopolitical disasters were to occur.
For more information on the environmental impact of meat production and consumption, see the ethics of eating meat. Reducing meat consumption, perhaps to a few meals a week, or adopting a vegetarian or vegan diet, alleviates the demand for environmentally damaging industrial meat production.
Buying and consuming organically raised, free range or grass fed meat is another alternative towards more sustainable meat consumption.
Organic farming is a rapidly emerging trend in the food industry and in the web of sustainability. According to the USDA National Organic Standards Board NOSBorganic agriculture is defined as "an ecological production management system that promotes and enhances biodiversity, biological cycles, and soil biological activity.
It is based on minimal use of off-farm inputs and on management practices that restore, maintain, or enhance ecological harmony.
The primary goal of organic agriculture is to optimize the health and productivity of interdependent communities of soil life, plants, animals and people. In addition, organic farming prohibits or strictly limits the use of manufactured fertilizers and pesticides, plant growth regulators such as hormoneslivestock antibioticsfood additives and genetically modified organisms.
See organic certification for more information. Urban gardening[ edit ] "Edible landscaping": Qixia DistrictNanjingChina In addition to local, small-scale farms, there has been a recent emergence in urban agriculture expanding from community gardens to private home gardens. With this trend, both farmers and ordinary people are becoming involved in food production.
A network of urban farming systems helps to further ensure regional food security and encourages self-sufficiency and cooperative interdependence within communities. For instance, vegetables and fruits raised within small-scale gardens and farms are not grown with tremendous applications of nitrogen fertilizer required for industrial agricultural operations.
The nitrogen fertilizers cause toxic chemical leaching and runoff that enters our water tables. Nitrogen fertilizer also produces nitrous oxidea more damaging greenhouse gas than carbon dioxide. Local, community-grown food also requires no imported, long-distance transport which further depletes our fossil fuel reserves.
Communities can work together in changing zoning limitations in order for public and private gardens to be permissible. Such sustainable, organic farming techniques include: Food preservation and storage[ edit ] Preserving and storing foods reduces reliance on long-distance transported food and the market industry.
Home-grown foods can be preserved and stored outside of their growing season and continually consumed throughout the year, enhancing self-sufficiency and independence from the supermarket.

Sustainable transport A carsharing plug-in hybrid vehicle being used to drop off compost at an urban facility in Chicago. With rising peak oil concerns, climate warming exacerbated by carbon emissions and high energy prices, the conventional automobile industry is becoming less and less feasible to the conversation of sustainability.
Revisions of urban transport systems that foster mobility, low-cost transportation and healthier urban environments are needed. Such urban transport systems should consist of a combination of rail transportbus transportbicycle pathways and pedestrian walkways.Jan 13, · Check out our top Free Essays on Essay On Green Building to help you write your own Essay.
The Green Island Group in WWII Two Atolls: Nissan, Barahun, Sirot, Hon Pinipel and Sau It never caught the public imagination like Midway or Iwo Jima. But the tiny Green Island atoll just below the equator in the South Pacific was a busy crossroads of WWII.
This free Environmental Studies essay on Essay: Green buildings is perfect for Environmental Studies students to use as an example. Green architecture is an approach to building which has become more popular in the last 25 to 30 years. Also known as sustainable design, green architecture is a method of design that minimizes the impact of building on the environment.
Once thought of as unconventional and nonstandard, both. Green anarchism (or eco-anarchism) is a school of thought within anarchism which puts a particular emphasis on environmental issues.A green anarchist theory is normally one that extends anarchist ideology beyond a critique of human interactions, and includes a critique of the interactions between humans and non-humans as well.
This often culminates in an anarchist revolutionary praxis that is.
