Reduce the consumption of products 

This step affects all areas of our life: If you take a closer look, every product that we don't need to survive is a luxury. So just buy less. It begins at the supermarket with a chocolate bar and ends with a new smartphone, car or whatever you wanna buy. Ask yourself if you really need it. Especially the internet in particular tempts us to make spontaneous purchases. Before you klick the order button wait 48 hours. If you still wanna have it, buy it. This will also help you to make the next step...

Avoid returns when online shopping

Do not buy the same sweater in three different sizes. Try to figure out which size fits and order only one. If you are not sure about a product, do not buy it online.
