Don't throw away plastic
When plastic gets thrown in the sea/ocean, there are several
consequences. Whether it be: sea animals suffocating from plastic,
unknowingly switching diets from nutritional food to hardy
plastics, or even falling victim to the murderous plan of a piece
of debris, it all leads to death.
Re-use plastic bags
If you see your relatives or close friends throwing away plastic
bags, tell them not to. Make them realize that by throwing a
single straw down the drains it's desnination is in a sea life
stomach.
Help Clean Up the Beaches
Gather some friends and tell them that you're going to go pick up
plastic and any trash that doesn't belong to be on the beach. Tell
them it's for a good cause, otherwise we're going to have beaches
filled with plastic, they should know that plastic on the beach
means no more late afternoons out on the beach.
