Answer:
Dear {Name},
Litter is more than an eyesore on city streets and along highways. I am personally very concerned with this topic. Littering can cause damage in water pipes in the ground, pollution,and allows toxic chemicals to go into places they shouldn't be, which can create quite a mess.{Where you live}Has a growing concern for littering to me, and i think that there should be some action taken over this. A vast amount of the plastic garbage littering can travel all the way the surface of the ocean, All the way from here, Which is also a problem. It can get ocean animals sick, It can get land animals sick.
Please do something about this. I'm counting on you {Name}!
:) Hope this helped !!! (You can change some of it to tweak it a little so it sounds like it's from you.)
