Plastic pollution is having a colossal impact on our oceanic ecosystems. Small Island Developing States (SIDS), in particular, experience a deluge of plastic waste either washing up on their beaches or from plastic they generate themselves. These vulnerable economies, primarily dependent on tourism and fishing, can be devastated by pollution. Since 2019, Searious Business has been working with the IUCN on their "Close the Plastic Tap" Program to mitigate plastic pollution on six Caribbean and Pacific islands. Several options and methodologies were shown to work well—but a holistic approach is needed—hence this Blueprint to guide the way.
