There are little ways in which you can contribute everyday to reduce waste and care for the environment. Think twice before crumbling that piece of paper. If the back is blank, cut it in half or four pieces and use it as scrap or doodle paper. Staple a couple and use it as a small note pad that you can carry in your bag, for when ideas come to you. There are many other uses that you can think of. Use it as packaging material, shredded or crumbled. Or as paper to test your pens before you write.
How about that ink cartridge? Take it to your supply store when it is empty, sometimes you get discounts for recycling them. Print in fast or economy mode to save ink. Print in black and white if you don’t need the color; why waste color ink if you don’t need it? You can reuse the small plastic container where the ink cartridge comes and use it to plant seeds. Keep your PC in energy-saving mode if you are going to be away from it for a while.
There are many things that you can do to contribute to a greener environment as a writer. I am sure you can come up with some according to your daily writing routine. Be a green writer!
