Understanding the difference between wants and needs of a teenager is super important to express and cut our carbon footprint. Needs are things you are urgent to need like food, shelter, and clothes. Wants are a total different things than need. Wants are things that are extra that make life easier and makes it more fun for you. A lot of our carbon footprint comes from the things that we want. Things that we don't really need but have a desire for. Things like travel, buying a lot of useless items, and  energy usage. If we really think about it and get the things we really need instead of things that are extra, it might affect the amount of carbon we have in our footprint. This helps out planet out and us at the same time. This can change the amount of carbon in the world.
