4. Climate change: The production and disposal of plastics contribute to greenhouse gas emissions, which contribute to climate change and the degradation of the environment. 5. Wildlife impacts: Animals can mistake plastic waste for food, leading to ingestion and potential harm or death. Marine animals are particularly vulnerable to plastic pollution, as plastic waste can entangle or suffocate them. 6. Microplastics: Plastics break down into smaller pieces called microplastics, which can be ingested by organisms and enter the food chain. This can have cascading effects on ecosystems and human health.
