1. Go to the woods. Bring a pinecone home.

2. Put the cone in a pot with some soil - so that most of it stands out.

3. Every day water it with a small amount of water, as excess water makes the cones rot.

4. After some time, a tiny tree will appear.

5. Congratulations - you just started oxygen production and you have a piece of forest in your own home.

Thank-you for doing something for nature!
