Sounds easy enough
  1. If we all ate less meat
    Not full on vegetarian, just don't eat meat like one or two days out of the week, is that really so hard people??
  2. Stop drinking bottled water
  3. Read more books
  4. Walk places when you can
    You feel better when you do, trust me
  5. Be kind
    Be selfless. Not everything is about you, everyone has issues they're dealing with, and you would want others to be considerate of you so just do the same for them.
