Just a Random Off Topic Question here; I am planning to spend the earth day this year with my family. I would like to let my children know that what are the steps that we have to take in order to save the planet and save our future generations as well. For this, I and my children are going to plant a tree in our garden. I need a suggestion if any of you have even a little bit of knowledge about gardening, let me know which plants should I grow this 22nd of April on the occasion of earth day.
