Why plastic waste matters locally
An estimated 33,000 tons of plastic enters Bali’s rivers every year, endangering marine life and the 90% of Bali’s residents who live within 1 kilometre of a river. Although Indonesia has pledged to reduce 70% of plastic pollution it emits into the ocean by 2025, trash continues to pile up in and alongside rivers largely due to the lack of waste management and recycling infrastructure. To tackle this problem, Sungai Watch installs Trash Barriers along waterways and carries out daily cleanups at each site. With these barriers, they have been able to collect data on pollutants and kickstart conversations with local communities on how to curb plastic plastic pollution. Sungai Watch also engages hundred of volunteers to carry out emergency cleanups at illegal landfills and runs an active hotline for community members to report landfill sightings.
Why plastic waste matters globally
The impacts of ocean plastic pollution are manifold — from disrupted marine ecosystems to the inadvertent consumption of hazardous microplastics to the contamination of groundwater, we’re facing a plastic emergency of unprecedented scales. Since more than 80% of plastic pollution in the ocean comes from rivers and streams, it follows that one of the simplest ways to clean our ocean is to start in our rivers. Sungai Watch is paving the way with their mission to place trash barriers in every river in Indonesia by 2025 and eventually the world.
