Sustainability is expressed as meeting present environmental, social, and economic needs without compromising these factors for future generations A practice cannot be said to be 'sustainable for X years/generations.' The use of any span of time disqualifies the activity. Sustainability is for perpetuity.
Sustainability also means greater efficiency in resource use, ultimately giving benefits to economic growth and overcoming poverty, as well as health and quality of life.
Sustainable design and sustainable development are critical factors to sustainable living. Sustainable design encompasses the development of appropriate technology, which is a staple of sustainable living practices. Sustainable development in turn is the use of these technologies in infrastructure. Sustainable architecture (see Green building) and agriculture are the most common examples of this practice.
When I first thought of making jelly
, I didn't realize that it was a definite challenge and art. When I visited with Eppel Beard, she made it look so easy. She gave no hint that it might be hard to make a perfect clear jelly with the colors vivid and beautiful that when taken from the jar would hold its shape. But when I tried to make jelly on my own for the first time, I chose a fruit low in pectin, put too much sugar in it and didn't cook it long enough. It turned out like syrup. I tried again and cooked it too long. When it hardened it made a very good candy. Soon I found my mistakes and tried again and it turned out all right.
Like most people, I had thought that it wouldn't be very hard to make jelly because I reasoned, all I'd have to do was follow the recipe on the box of pectin. But Eppel said the real challenge is to make jelly like women did before the age of packaged products and commercial pectin, when they depended on the natural pectin and acid in the fruit.
