It is generally known that plastic is a crucial problem in the ocean as it can be harmful for hundreds of marine species such as seabirds, fish, whales and others. This happens since those sea creatures smell plastic like food. In fact, the amount of trash made of plastic in the ocean is around a quarter of a billion metric tons which form in tiny or rice-sized particles in 2004. This attracts over 200 marine animals feed them. Turtles often eating plastic due to its similar appearance to jellyfish is a current phenomenon to illustrate this. How can it occur? As the primary diet for many seabirds, krill consumes algae as their food. Then, algae break down in the ocean and emit dimethyl sulfide (DMS) which has sulfur odor to lead seabirds finding their feeds in the ground. Unfortunately, they consider plastic as krill to be their food. Matthew Savoca, a doctoral student at the University of California, said that DMS looks a dinner bell. It will give a signal for seabirds to find krill with their foraging mode.
