12 Contoh Soal UTBK SNPMB 2023 dan Jawabannya agar Masuk PTN

In 2010, researchers estimated that 8 billion kg of plastic entered  the ocean in a single year, and that number would sharply increase by 2025. When it enters the ocean, plastic waste disrupts marine ecosystems, travels to central locations, and forms a trash island which can cover an area of more than 1.6 million square km. These plastics never degrade, but rather break up into smaller sizes. They eventually become microplastics that stay in the environment for hundreds of years.

Scientists at the University of California San Diego have invented a new biodegradable material that is designed to replace the commonly used plastics. The material started to biodegrade in seawater within four weeks. The team found that various marine organisms colonize the material and break it into nutrients for their consumption.

The research of this new plastic is joined by experts in biology, chemistry, and marine science. They have shown that it is possible to make durable plastics that also can degrade in the ocean. Plastics should not be going into the ocean in the first place. But now, if they do, this new plastic can become food for microorganisms and not harmful trash.
