Read the following and choose the correct answer to each of the following questions. Being environmentally conscious is not all about plastic bags;it's about making a lot of everyday choices. People can be more environmentally conscious through many actions. Firstly, recycling conserves natural resources, reduces pollution and saves energy. Recycling involves sorting and cleaning up trash to produce "secondary materials" - mainly glass, paper , metaland plastic-for reuse in products Recycled aluminium, for example, is a particularly valuable resource;manufacturing using recycled aluminium is 92% more efficient than when unused raw materials are used , according to the Aluminum Association. About 40% of the country's aluminium supply comes from recycling, but people are still throwing away nearly 1 billion worth of aluminium cans that could have been recycled every year. Secondly, people should pay attention to plastic bags. They take hundreds of years to break down and cause a particular threat to wildlife . Hundreds of thousands of marine mammals die every year after mistaking plastic bags as food. Many animals get trapped in plastic bags and die. Therefore , people can decline the number of them when they bring their own bags . Use and reuse all those bags - paper,, plastic, cloth -whether or not they are designed to be "reusable." If they become too old to carry new purchases, use them to pick up litter. And, finally , dispose of them properly - recycle them if you can.
