Abstract
My PhD work achieved the first comprehensive understanding of plastic pollution in the Galápagos, including the species affected, those at greatest risk, and the identification of pollution sources. It also established a baseline for health and plastic pollution metrics in endemic and native species such as marine iguanas, green sea turtles, and black-striped salemas. Our findings revealed plastic pollution in all wildlife habitats surveyed, including water, sediment, and beaches, as well as in 91% of the sampled marine wildlife populations. While current plastic pollution levels are not severe enough to cause immediate health problems, the presence of such pollution in Ecuador’s pristine and protected areas is alarming. Our study provides the first insight into the knowledge gap between wildlife health and plastic pollution, utilizing state-of-the-art research techniques. Our results have already been used as a foundation for solid scientific arguments and concrete actions to address the global issue of plastic pollution, such as in the negotiations of the plastic treaty, where Ecuador is an active participant. Overall, the findings of this PhD research emphasize the pervasive nature of plastic pollution globally, including the Galápagos, and highlight the urgent need for comprehensive mitigation strategies to protect the region's unique biodiversity while there is still time to act.
