Within society you have:
Greatest Human Needs
Lesser Human Needs
In the current global situation some of the needs have been shifted.
There is a lot of talk about global warming etc. and resources are having to be used to carefully and sparingly. A big result of these issues are sustainable, ethical and economical ideas. They aim for our actions we take today not to impact badly upon the future of the environment.
This example shows how being good to the environment now is becoming a greater human issue than it was before.
