write a short note on disposal of plastic waste and conservation action
Answers
Answer:
Explanation:
Plastic pollution is the accumulation of plastic objects and particles (e.g. plastic bottles, bags and microbeads) in the Earth's environment that adversely affects wildlife, wildlife habitat, and humans.
Plastics that act as pollutants are categorized into micro-, meso-, or macro debris, based on size.
Plastics are inexpensive and durable, and as a result levels of plastic production by humans are high.
However, the chemical structure of most plastics renders them resistant to many natural processes of degradation and as a result they are slow to degrade.
Together, these two factors have led to a high prominence of plastic pollution in the environment.
Plastic pollution can afflict land, waterways and oceans. It is estimated that 1.1 to 8.8 million tonnes of plastic waste enters the ocean from coastal communities each year.
Living organisms, particularly marine animals, can be harmed either by mechanical effects, such as entanglement in plastic objects, problems related to ingestion of plastic waste, or through exposure to chemicals within plastics that interfere with their physiology. Effects on humans include disruption of various hormonal mechanisms.
