A new documentary highlights the plight of marine animals living among the estimated 5 trillion pieces of plastic rubbish generated by humans.
Microplastics are a major ecological concern causing damage to marine life.
Microfibres and microplastics are a massive problem for marine life. Once ingested, they
severely affect marine animals ability to eat. There's also concerns about their toxicity.
Many seabird species, including the blue petrel (Halobaena caerulea), consume plastic at sea because algae on the plastic produce an odor that resembles their food sources.
Thousands of seabirds die every year from consuming plastic trash in the oceans. But why do they eat plastic? New research shows that it produces odors that help some species find prey.
Seagrass meadows are often overlooked by the public but vital to the ocean ecosystem.
Seagrass is more than just a bit of sea greenery.
Around 94% of litter on South African beaches is made of plastic, of which 77% is packaging.
