What are the 3 worst effects of plastic pollution?
These include: Physical impact on marine life: entanglement, ingestion, starvation . Chemical impact: the buildup of persistent organic pollutants like PCBs and DDT. Transport of invasive species and pollutants from polluted rivers to remote areas in the ocean.
How does plastic negatively affect humans?
Microplastics entering the human body via direct exposures through ingestion or inhalation can lead to an array of health impacts, including inflammation, genotoxicity , oxidative stress, apoptosis, and necrosis, which are linked to an array of negative health outcomes including cancer, cardiovascular diseases, ...
What are the problems with plastic?
Larger items, such as plastic bags and straws, can choke and starve marine life , while smaller fragments (microplastics) can cause liver, reproductive, and gastrointestinal damage in animals. Humans are also vulnerable because we eat fish and other animals rife with microplastics.
Do we need plastic?
Plastic is durable and provides protection from contaminants and the elements. It reduces food waste by preserving food and increasing its shelf life. It protects food against pests, microbes and humidity. Without this protection, food is more likely to get damaged and become unusable.
