3、able Communities According to the World Wildlife Fund, people are currently using resources 25 percent faster than they can be replaced. If we continue down this course, we will need a second planet by the year 2050. Sustainable communities attempt to change that course by drastically altering how c
4、itizens interact with the environment. Alternatively known as green communities or ecovillages (生态村 ), sustainable communities vary in their approaches to sustainable living, or a way of life that meets the populations basic needs in ways that can be continued indefinitely for future generations. So
5、me communities focus solely on enriching the environment, while others also aim to improve social and economic conditions as well. Characteristics of Sustainable Living Communities Sustainable communities generally strive to minimize waste, reduce consumption and preserve open space. Ideally, they d
6、ont use resources faster than they can be replenished, and they dont produce waste faster than it can be assimilated back into the environment. Granted, some communities are more radical than others-living entirely off the grid and eschewing the use of government:-printed money-but the basic princip
7、les are similar. Designing the neighborhood to encourage walking or bicycling is one way sustainable communities put these first two principles into practice. Less driving means less gas and emissions. Many ecovillages also incorporate work space into homes or encourage telecommuting. They also migh
8、t zone part of the development for commercial use, essentially making the community a serf-contained environment where residents dont even have to leave for shopping or entertainment. This design sometimes is called a live- work-play lifestyle. Using green building techniques is another staple of su
9、stainable communities. Here are a few examples: . Architects design buildings to take advantage of the suns lighting and heating capabilities. . They install energy-efficient appliances. . They try to use local sources of materials as much as possible to cut back on the environmental costs of transp
10、ort. . They build with durable, non-toxic materials that have either been recycled or sustainably harvested. You might see straw bale (草捆 ) houses, which essentially use bales of straw as the structural building blocks; cob houses, which are a mix of straw, clay and sand or earthbag homes, which are
11、 exactly what they sound like, homes made out of bags of dirt. Along with green building techniques, sustainable communities rely on green gardening methods. They landscape with native, drought-tolerant plants and raise them organically to reduce water and keep pesticides and herbicides out of the e
12、nvironment. Many communities also set aside a significant portion of their land as open space. Serenbe, for example, reserves 80 percent of its 900 acres for green space, that is, 720 acres of rolling hills, woods and streams free of development, quite a contrast to the concrete-laden urban sprawl o
13、f Atlanta just 32 miles away. Another way sustainable communities reduce their ecological footprint is by capturing and recycling their wastes, often creating their own contained natural cycles. Instead of treating normally perceived waste products such as rainwater and sewage as pollution to be got
14、ten rid of, residents mm them into resources. Sewage, for example, is turned into compost that fertilizes plants and increases soil productivity, while captured rainwater is cleansed through innovative filtering systems and reused for watering plants. Examples of Sustainable Communities More than 40
15、0 ecovillages exist in the world, according to the Global Ecovillage Network database. The following examples outline life in just two of these communities. Dancing Rabbit Ecovillage, Missouri. Dancing Rabbit Ecovillage is a developing 280-acre community in northeastern Missouri with far-reaching go
16、als. It aims to be an entirely self-reliant town that practices “radical environmental sustainability, according to the communitys website. The towns founders hope to attract between 500 and 1 000 residents to create a diverse community more capable of providing for all of its own needs. Dancing Rab
17、bit even has its own local currency to encourage local trading and sourcing of jobs. The ecovillage has established a set of six guidelines that may seem extreme to the lazy environ- mentalists among us, but should set the town well on its way towards achieving sustainability. 1. No vehicles are to
18、be used or stored in the village. 2. Fossil fuels for cars, refrigeration, heating and cooling homes, as well heating domestic water arent allowed. 3. All gardening must be organic. 4. All power must come from renewable resources. 5. No lumber from outside the local area is allowed unless it is recy
19、cled or salvaged. 6. Organic waste and recyclable materials are to be reincorporated into usable products through composting methods. Long term, Dancing Rabbit citizens are trying to achieve negative population growth. If they want the current 50 or so residents to become 500 or I 000, they may want
20、 to rethink that last guideline. Los Angeles Ecovillage, California. You might think sustainable communities have to be set in the country, but thats not true. Located just three miles west of downtown Los Angeles, the Los Angeles Ecovillage (LAEV) is a community of 500 residents seeking to have min
21、imal impact on the environment while also providing a fulfilling way of life. The urban location near public transit, schools, churches, commercial services and industry helps residents drive less, while the dozens of gardens and fruit trees provide a local source of food. LAEV takes a whole-systems
22、 approach to sustainability, meaning that residents strive to balance the social, economic and environmental needs of the community. Here, clean water and air rank up there with close-knit relationships, ethnic diversity and affordable housing. Citizens have saved 20 tons of brick from the landfill
23、to use in construction projects, composted over 100 cubic yards of yard waste and held countless weekly potluck dinners to establish and strengthen relationships. Who knew that sustainability could be possible even in one of the largest, most polluted cities in the United States? Other Eco-Friendly
24、Communities Residents of the two sustainable communities we just discussed deliberately placed sustainability at the top of their agenda. But communities spring up for lots of reasons not related to the environment, and sometimes the Earth benefits. Before “green“ was the new buzzword and sustainabi
