Old academicians, by default, did have a continuously non-boring changing environment while they carried out sustainable practices that kept them going for decades.

In a changing environment, the senior academicians have seen continuous input "the new students" & continuous output "the graduates" as well as the colleagues who join & the colleagues who quit or leave. Besides that, they saw the always changing study programs, courses, textbooks, and research dissertations.

When there is a free atmosphere, innovative scholars can suggest eco- & pocket- friendly options for all the staff & they may see that their reasonable suggestions are applied in a short time. In real life, we see that the daily professional lives are shaped in a certain frame & the scholars have just to fit in.

That is why life in a university has to be dealt with in the context of lowering expectations & assuming incoming negativism more than positivism. This is a key difference between universities in advanced countries & in 3rd world countries. You may serve for 2 years in a European university & finding these years more beneficial than serving for decades in a 3rd world university. The precise balance for weighing you & finding your true value is sadly far away from your country. Therefore, sustainability has to be linked with patience or tolerance within your homeland.

There are several steps academics can take to live their lives in a more eco-sustainable manner. Living this way will also cost a lot less. Some steps are:

1. Cut down--or better, eliminate--plane travel

2. Sell your car, if you have one; don't buy one if you don't.

3. Use non-motorised transport as far as possible--it's good for your health as well.

4. Adopt a low animal product, or better still, vegetarian or vegan, diet.

5. Overall, try to live simply in a material sense.

Patrick Moriarty Thank you Sir for your reply. The points you have mentioned are applicable to all human practices for being sustainable. My question typically confined to an academics professional life, where a teacher or a scholar can cut down their unsustainable practices.Waiting for your reply.

Mohamed Azab Thank you for the reply Sir. Please comment if I would like to add multi-page printing if visible to the reader or reducing space between lines can reduce down paper usages. Else, reducing the use of AC to cut down energy consumption etc. Please comment more, your contribution is valuable to me.

Thanks Arpita Chakraborty for your clarification. It's hard to think of many practices that would not also apply in general. Giving up on air travel to conferences might be one.

In my institution, we are using secure on-line tests on Blackboard in large classroom (over 100 students). Students take exams in a secure browser that they can only access the test. This methods saves tons of paper for exams. Even though papers can be recycled but we have to move the clippers or staplers for every single test booklet before throwing it to recycled bins.

Fanli Jia Thank you. But again this is an institutional sustainable effort. At individual level, what an academician like to act upon?

It's depends on people mind .but, for me if you ask i will say yeah

I'm simplifying my life with each passing day.
