Each year 8 million tonnes of plastic is deposited into theeach year, as we as humans are expected to produce and use 400 million tonnes of plastic each year by 2025. This will mean that even more plastic in the each year. This plastic is then eaten by animals in the sea, traps them as they swim, or pollutes their habitats. If this continues, the oceans will slowly have less and less life as more animals can no longer survive in their natural habitats. Take the quiz below to test your knowledge about what humans need to do now to save our oceans.
