Read the following passage carefully and answer the questions given below it. Certain words have
been printed in bold to help you locate them while answering some of the questions.
According to the United States Environmental Protection Agency (USEPA), plastic bags are a better
option than paper bags from the environment's point of view. Many studies comparing plastic versus
paper show that plastic bags have less net environmental effect than paper bags, requiring less
energy for transport, production and recycling and because of all these, plastic generates less
greenhouse gases. They cause less air and water pollution and can get compressed to a small size in
landfills. Plastic bags are sterile and thus are a better option for the transportation of eatables and
medicines.
However there is another side of using plastic. Plastics are manu-factured from petroleum. This brings
a host of other issues e.g. destruction of habitat. Their manufacturing invo-lves chemicals, many of
which have not been sufficiently tested for their toxicological impact on humans and animals.
Exacerbating the problem is that science has only advanced to detect plastic components in human
bodies and then link it to human ailments and diseases.
Where science has been unable to help is that it has largely failed to invent a solution to the hazards
caused by it. Making the situation dismal is the fact that the hazard is closer than it appears. Teflon,
PVC, Polyethylene, polysty-rene in utensils and various silicones in hair and body care products
accumulate in the body and lead to serious diseases.
Plastic producing companies are often chemical com-panies or subsidiaries of chemical companies,
both with poor track records when it comes to their adherence to regulatory compliance and their
willingness to perform toxi-cological analysis on the products that they make.
Plastics often drain component chemicals, including hazardous chemicals when temperature changes
beyond a certain point.
