Sustainability

 Sustainability is referring to a state or condition that can be maintained over an indefinite period of time. It is ability to sustain something. If an activity is said to be sustainable, it should be able to continue for very long time.
 Sustainability is somewhat contextual term. Sustainability according to my views is as;
“A process of change in which the use of resources, the direction of investments, use of technology , planning and acting, institutional change are all in harmony and enhance both current and future potential to meet human needs and aspirations”
 Sustainability also means balancing social, economic and environmental outcomes for current and future generations.
The recourses means all the things including natural or manmade, renewable or non renewable. For sustainability planning plays a vital role. Without planning sustainability could not be achieved.
The idea of sustainability is not new. The idea that depletion of resources should be controlled had come from very long times ago. Forest have many uses and values; they provide us with timber, clean water and air. For instant, in many countries of the world people cut fuel wood for cooking and heating and for other purposes from steep mountain slopes, which create problems such as soil erosion, seasonal flooding, and a declining water. For sustainability we have to plant new trees as we cut.
There are three principles of sustainability, environmental health, social equity and economic development.
In past our planet was regarded as a large natural system upon which human activity had very little impact. However, with the rise of industries and other climate changes people now wonder what the world might be like in the future. Many people believe we cannot sustain our current way of living. This concern has led to thinking about how best to sustain life on earth.
Sustainability is complex and considered to be a relative rather than an absolute state and it is dynamic not static. Sustainability is something on which we have to continue to work on it, because things are always changing as population and climate change etc.
