What is the official definition of Sustainable Development?

Sustainable development is using the resources available to you today in a hammer that willow impair the ability of future gyrations to benefit from them as well. It could also mean that you use materials full to maximize their use without the creation of waste.

A good example would be a grandmother in the 1950's who would organize a festive supper (say a turkey diner) by buying enough food for the guests taking into account their numbers and tastes, serve the food. then saving the residual food for cold turkey dinner the next day, turkey Sandwiches and casserole the next, turkey south next and eventually adding the bones to the compost heap. She would also repair cloths, cut them down for the smaller kids and eventually teat them up for rags or use them in quilts.

In both these cases she would maximize the use from what she had.
