Marine biodiversity is in a state of alarming decline, as key species such as whales, sharks, and sea turtles are endangered by habitat destruction, pollution, and excessive fishing. Currently, a mere 8.2% of the world's oceans have protection. There is an urgent requirement to secure an extra 23% as protected areas by 2030. Milkywire supports organizations committed to preserving marine life by engaging in direct protection efforts, conducting research, and generating knowledge. Additionally, we endorse projects aimed at establishing marine protected areas at both national and local levels.

The escalating plastic crisis threatens marine life, annually, 11 million metric tons of plastic enter our oceans, joining an existing 200 million metric tons. There is a critical and pressing need to reduce the volume of plastics and other debris currently polluting marine ecosystems. Milkywire supports organizations that are involved in plastic reduction and other cleanup efforts aimed at minimizing waste in the oceans.

Mangroves, seagrasses, and other marine ecosystems act as carbon sinks, and shield coastal regions from storms, erosion, and help maintain water quality. They provide economic benefits through industries like tourism and fisheries and carry cultural importance as well. Milkywire supports numerous projects aimed at safeguarding and rejuvenating mangroves and other marine ecosystems for future generations. We support organizations that engage in grassroots efforts and work closely with local communities, while also advocating for policy changes at both the local and national levels.
