Protecting the World’s Oceans

One of the biggest identified threats to sea life is plastic pollution. Everyone can help by reducing the use of plastic items and recycling rather than throwing plastic away. In addition, we can participate in beach clean ups, picking up any litter found near or in the sea. We can also raise awareness so that everyone is united in the need to reduce plastic usage and help protect Earth’s wonderful oceans and seas.
