From the website of Clean Miami Beach, cleanmiamibeach.org 

Our mission is to keep our community and natural habitats free of garbage and other harmful land pollutants with a focus on single-use plastics. Single-use plastics such as grocery bags, food packaging, bottles, straws, containers, cups and utensils are extremely damaging to the unique fragile ecosystem of Miami Beach and its marine wildlife.

Our goal is to provide a clean place for our residents and visitors, and a safe environment where our beautiful wildlife can thrive.

We achieve this by

Mobilizing the community for weekly beach and wetlands clean ups

Working with and advising local businesses to promote sustainable business practices

Educating and spreading awareness about the negative impact of single-use plastics on our ecology

Proposing and supporting local ordinances drawn to protect the natural habitat of our marine wildlife
