Using computers for distributing/collecting assignments instead of paper

This may be something for teachers to look into. Instead of students receiving handouts/assignments on paper, students can receive them online via computer and also send them once finished back online.

This could reduce the consumption of paper resources. I understand that data on computer takes up hard disc space but hard disc space can contain much more data than paper. Additionally once data is used on hard disc it can be deleted clean, unlike paper which needs to be recycled and cannot be used again the same way.

Some university professors do require/accept assignments returned online.

If this practice was more common it would significantly help the environment and conserve resources.

Using magiboards and blackboards for public demonstrations instead of placards

For those who are politically active and take part in public demonstrations- especially environmentalists, a great way to post public messages in demonstrations is to stop using placards which take up paper resources. Typical usage of placards for public demonstrations pictured below:

Using a placard only allows a message to be written once. But by using a magiboard or blackboard to display a message, you can erase it and use it again and again. This will also reduce paper resource consumption as well as costs.
