Microplastics are defined as fragments of any types of plastic that are less than five millimeters in length, or about the size of a sesame seed. Despite of its extremely small size, the current volume of microplastics in the environment, especially in the oceans, is worrisome, as they can endanger the ecosystems and contaminate our food chain. Many studies show that microplastics in the oceans are being consumed by some 700 aquatic species. Ingesting this tiny plastic waste can be very harmful to animals as well as humans, due to its physical and chemical toxicity. In this episode, Assoc. Prof. Dr. Suchana Chavanich, marine biologist at Faculty of Science, talks about the dangers of microplastic, while Dr. Sujitra Vassanadumrongdee, senior researcher at Environmental Research Institute, discusses how to better manage plastic waste. Both are from Chulalongkorn University.
