Cape Town’s urban landscapes were transformed into lively murals advocating for ocean conservation and community activism through Sea Walls South Africa, an initiative by the PangeaSeed Foundation in collaboration with the Save Our Seas Foundation. The event brought together 18 muralists to address urgent marine issues such as plastic waste and community involvement in protecting marine life. The murals serve as educational devices advocating for ocean care through imaginative storytelling and embody the concept of ‘artivism’, symbolizing the transformative power of art in inciting change.
