This is an easy one - Spread the word about conservation!
Talk to friends, family, co-workers, and people you randomly meet! Any way you can, get people to think about the earth. There are more than 6,000,000,000 people on this earth, and every one of them needs to take care of it! Always look for environment-safe products and encourage others to do the same. From recycling to buying less packaging to planting trees to saving water to conserving energy, keep the environment in mind!
As always, please feel free to comment with questions, or anything to add!
