You can read many reports written by UNEP or GESAMP. These reports can easily be found on internet.

Dear,

I often use the following data to explain how serious the microplastics problem is.

1. By 2050 the amount of plastics debris flowing ocean will equal to the amount of fishes.

2. By 2030 the amount of plastic debris flowing ocean will be half of the amount of fishes.

3. By 2025 the amount of plastic debris flowing ocean will one-third of the amount of fishes.

These data are easy to explain how serious the microplastics porblem is for non-experties.

Thank you.

Sorry but if you do not cite any bibliographic references, your data have no credibility.

Interesting question there.....

However, within the larger picture, the impacts of research activities on the environment in terms of plastic production vary widely depending on the type of research being conducted. For example, research into plastic production processes may involve the use of large amounts of energy, water, and other resources, leading to increased pollution and waste. Additionally, research into new plastics and plastic alternatives may require the testing and disposal of potentially hazardous materials, which can lead to pollution and environmental damage. Finally, research into the effects of plastic production and use on the environment may result in additional pollutants, such as microplastics, entering the environment.
