A definition of a need is something that a person must have, something that is needed in order to live or succeed or be happy. This differs from a want because a want is a desire or wish for something. Things like food are things you need, but stuff like electronics is not a necessity. Even some foods aren't needs, like ice cream. Ice cream is a need that you don't necessarily need to eat to survive. You need to eat protein, vitamins, and minerals. How you get them is up to you (and your family). You can eat meat, nuts, or soy products to get protein. You can get fruits and vegetables to get vitamins and minerals. You can eat yogurt or cheese to get other vitamins and minerals. You can eat bread to get still more vitamins and minerals. These basic kinds of foods are needs.
   Another example is liquid. Your body has to have liquid to survive. Water is a good liquid to drink because it keeps you healthy. Milk and fruit juice are also good because they give you vitamins and minerals your body needs without giving you the fat and excess sugar found in cola. Still, cola tas tes good. Drink a Pepsi or Coke or Mountain Dew or Sprite and you feel good because it tastes good. But you don't need that cola to survive.

I totally agree. Plus with the fact no one really recycles anymore which is bad but if we buy all this stuff we aren't helping the environment then drinking or eating too much can make you sick. We really should differentiate between needs and wants
