Our seas, whether you get hot or cold, they are absolutely necessary for all life on earth. Nevertheless, 8 million tons of plastic waste ends up in our oceans each year. Yes really: 8,000,000,000 kilos. By refilling this capper bottle with tap water, you drink the gulp clean the oceans. Because a Dopper easily saves 40 PET water bottles per year. May sound like water to the sea, but every step is a giant leap forward for the oceans!
