For example:
A lot of things we buy in the supermarket are in plastic packets and boxes. It's convenient to
buy meat or fruit or vegetables that are in packets or boxes because it makes shopping quicker and it keeps the products fresh and helps it last longer. However, it is wasteful as most people don't recycle the packets.
