1. Go to the woods. Bring a cone.
2. Put the cone in a pot - so that most of it stands out.
3. Pour it every day with a small amount of water, as excess water makes the cones rot.
4. After some time, a tiny tree will appear.
5. - they just started oxygen production and you have a piece of forest in your own home.
You're doing something for nature, and you'll see what nature does for you.
