The Coldest Beach Cleanup Initiative
The Coldest Beach Cleanup Initiative was founded to improve our beaches, waterways, and oceans while meeting others and networking.
The oceans face a massive and growing threat from something you encounter everyday: plastics. An estimated 17.6 billion pounds of plastic leaks into the marine environment from land-based sources every year—this is roughly equivalent to dumping a garbage truck full of plastic into the oceans every minute.
Every month our team, together with Coldest Volunteers around the world dedicate hours, resources, & technology into removing plastic from our oceans. Learn more
