Activity 3.3.3 – My Plastic Use
“Throughout human existence water has faced a continuous threat of pollution, and while the threat of pollution has remained constant, the types of pollution have evolved and expanded over time. Currently, freshwater ecosystems across the planet are being threatened by a new form of pollution—microplastic pollution.” (The Environmental Impacts of Microplastics: An Investigation of Microplastic Pollution in North Country Waterbodies by Samantha Haab Kimberly Haab; page 9) . Microplastics are tiny plastic particles measuring less than 5 millimeters in diameter. They can be categorized into two main types: primary microplastics, which are deliberately manufactured at small sizes (such as microbeads in cosmetics and industrial abrasives), and secondary microplastics, which result from the breakdown of larger plastic items due to environmental factors like sunlight, heat, and mechanical abrasion. These minuscule plastic fragments are now ubiquitous in the environment and pose a grow...
