Sustainability 

I believe sustainability means to be able to focus on what is needed to be done to develop in a positive way without comprising any future development. My definition has not really changed for I truly think there are many way one can define this term and what a individual thinks can be sustainable. This is range in many different aspects such as the Earth’s biosphere or human civilization furthermore there are different ways on things can be sustainable not just to physical things but also things such as mental health or emotions.
