Delineating the global plastic marine litter challenge: clarifying the misconceptions

Plastics, owing to their various beneficial properties (durability, flexibility and lightweight nature), are widely regarded as the workhorse material of our modern society. Being ubiquitously and increasingly present over the past 60 years, they provide various benefits to the global economy. However, inappropriate and/or uncontrolled disposal practices, poor waste management infrastructure, and application of insufficient recycling technologies, coupled with a lack of public awareness and incentives, have rendered plastic waste (PW) omnipresent, littering both the marine and the terrestrial environment with multifaceted impacts. The plastic marine litter issue has received much attention, especially in the past decade. There is a plethora of articles and reports released on an annual basis, as well as a lot of ongoing research, which render the issue either to be overexposured or misconstrued. In addition, there are several misinterpretations that surround the presence and environmental impact of plastics in the oceans and, consequently, human health, that require much more critical and scientific thinking. This short communication aims at unveiling any existing misconceptions and attempts to place this global challenge within its real magnitude, based either on scientific facts or nuances.
