There are many things we can easily do everyday to really help!
Let's call these things "low hanging fruit", things easy to reach with a quick benefit!
Plastic Straws
"Dont"
Fast food throw cups
"No way"
Lighters
"Quit, yes you can"
Disposable bags
"Canvas bags"
Styrofoam cups
"Use a mug"
Try this!
During the course of one single weekend, "record" all the "disposable-plastic" you use for any reason.
Grocery bag, Candy Wrapper etc anything you use, then throw away.
"Try it", You will see why there is such a thing as a Pacific Garbage Patch very quickly!
Then the following weekend "try not to use those things!
