Plastic is a environmental hazard. Justify the statement
Answers
Answer:
Plastics have become an indispensable part of the society. Lightweight, easy handling, durability, flexibility, resistance to water, and other microbial attacks have made them ubiquitously popular. The extensive use of the long-lived polymer has confronted the environment with a challenging plastic pollution problem. Plastics are the product of coal, natural gas, crude oil, cellulose, and salt manufactured through energy-intensive technology. From cradle to grave, plastics affect the environment in a multifaceted way. The hazardous and ecologically (terrestrial and marine) damaging threats necessitate its removal from the environment. Incineration, landfilling, recycling, and degradation are the four most available options to manage the plastic waste. However, to avoid long-term environmental damage, degradation of plastic is the most preferred option among the management options. Plastic degradation is carried out by photodegradation, thermooxidative degradation, hydrolytic degradation, and biodegradation. Among them, microbial degradation using bacteria and fungi is an emerging strategy to manage plastic waste. Hence, this chapter highlights the benefits, concerns, and threats surrounding the use of plastics. The different perspectives covered in this chapter include plastic production and plastic waste generation, environmental and health effects of plastic pollution, plastic waste management options, biodegradation of plastic polymers and the mechanism involved, biodegradable plastics, and challenges and constraints of plastic waste biodegradation.

Answer:
It is. 9 bio gradable plastic so when the plastic article ki por accuminatum in the grounding and pollute the environment the waste plastic article are thrown here and there careless into dry water drain and clock them which caused her and hygienic condition.
Explanation:
When? When the animals eat at the plastic then it causes sloka in the respiration system it Kajal and it causes that when the plastic waste material are burnt they produce gas. They are great. But so they does not discompose easily. Make me brain list.
