1.Read the text carefully and find the sentence(s) describing the hazards of plastic bags.
Plastic bags cause litter and are a danger to wild animals,which mistake them for food.It takes hundreds of years for plastic to break down,but much less time for paper.
2.Read the text carefully and find the sentence(s) describing the truth about the third “green truth”.
It is the production of food,not its transport,that uses most of the energy and produces most of the greenhouse gases.In some cases,local produce might have used more energy and produced more greenhouse gases than produce grown a long way away—even taking into account its transport.
