Sustainability
My definition of sustainability focuses on the ability to live life with the best quality without compromising the ability of the next generation to live the same. To deliver a good quality life to the next generation means delivering a good quality of Air, Water, Economy, and Society.
But the current scenario seems more challenging for establishing a legacy of good quality life for the upcoming generations. Attempting to establish the same seems like philanthropy and in fact, it is philanthropy. Though, this philanthropy requires the investment of time, money and resources. To invest these 3 (time, money and resources) you need to earn them first.
To establish a sustainable scenario first you need to make yourself sustainable. Those who have been able to sustain have sustainability and can stand. But those who are starting should understand the significance of sustainability first and then help the society for the same.
