Sustainable living is a lifestyle that attempts to reduce an individual's or society's use of the Earth's natural resources and his/her own resources. Often Sustainable living called as Green Living.
Practice of sustainable living often by altering methods of transportation, energy consumption and diet. To recall this lifestyle, Hong Kong Post has issued one set of four stamps and one specific shaped souvenir sheet feature Green living practice on April 14, 2011
The stamp of $ 1.40 presented a Conserve Water Practice.The typical home uses about one-third of their water outdoors, irrigating plants and watering lawns -- and up to half of that just evaporates.
Save water by irrigating only when it's really necessary, and water at dawn or after sunset to minimize evaporation loss. There are many other ways to conserve water outdoors, from weather-smart sprinklers to underground irrigation
The stamp of $ 2.40 presented an Clean Air Practice. The atmosphere is a complex dynamic natural gaseous system that is essential to support life on planet Earth. Stratospheric ozone depletion due to air pollution has long been recognized as a threat to human health as well as to the Earth's ecosystems.
Air pollution is the introduction into the atmosphere of chemicals, particulate matter, or biological materials that cause discomfort, disease, or death to humans, damage other living organisms such as food crops, or damage the natural environment or built environment.
The stamp of $ 3.00 presented a Save Energy Practice. Energy conservation refers to efforts made to reduce energy consumption. Energy conservation can be achieved through increased efficient energy use, in conjunction with decreased energy consumption and/or reduced consumption from conventional energy sources.
Energy conservation can result in increased financial capital, environmental quality, national security, personal security, and human comfort.
Recycling is processing used materials or wasted into new products to prevent waste of potentially useful materials, reduce the consumption of fresh raw materials, reduce energy usage, reduce air pollution (from incineration) and water pollution (from landfilling) by reducing the need for "conventional" waste disposal, and lower greenhouse gas emissions as compared to virgin production.
Recyclable materials include many kinds of glass, paper, metal, plastic, textiles, and electronics. Another form of recycling is the salvage of certain materials from complex products, either due to their intrinsic value (e.g., lead from car batteries, or gold from computer components), or due to their hazardous nature (e.g., removal and reuse of mercury from various items).
Proponents of sustainable living aim to conduct their lives in ways that are consistent with sustainability, in natural balance and respectful of humanity's symbiotic relationship with the Earth's natural ecology and cycles.
Sustainable living is fundamentally the application of sustainability to lifestyle choice and decisions. Sustainability itself is expressed as meeting present ecological, societal, and economical needs without compromising these factors for future generations.
We are obligated to future generations to protect our world. Clean air, clean water, green open spaces, national parks and preservation of our natural resources are everyone’s business. Human beings are dependent creatures.
