Study Notes
Plastic's Historical Context
- "Plastic is fantastic" was a popular phrase in the 1950s as mass-produced plastic became integral to daily life.
- The material is now ubiquitous, appearing in various products such as cars, furniture, and packaging.
Environmental Concerns
- Climate change and pollution from single-use plastics are raising questions about the reliance on plastic.
- Approximately 11 million tonnes of plastic waste enter oceans annually.
- Single-use plastics constitute 40% of global plastic pollution.
Human Health Impact
- Microbeads, tiny plastic particles, have been detected in the human body and can transfer from mothers to children through breast milk.
Production Issues
- Plastic production relies on fossil fuels, causing environmental issues throughout its lifecycle, including during extraction, transportation, and recycling.
Microplastics and Pollution
- Synthetic plastics do not biodegrade like natural materials (e.g., paper), which can be broken down by organisms.
- Only a limited number of plastic-eating microbes exist, making it challenging for plastic to decompose naturally.
Research and Solutions
- Dr. Sherry Mason, a chemistry professor, conducted award-winning research on microplastics, leading to a US Congress ban on microbeads.
- Rhodococcus ruber is a plastic-eating microbe tested for its ability to degrade plastic into basic components.
Future Considerations
- Emphasis on reducing plastic production, particularly in packaging, is necessary to mitigate pollution and its environmental impact.
