Every year more than 400 billion cups of coffee are sold , meaning that billions of plastic and cardboard cups are being thrown into the environment . I realised that taking your own mug to a cafe or coffee chain is one of the simplest things to do , yet nobody does it . For those who buy one , two or even three coffees a day , they could personally save between 365 - 1095 cups a year just by taking their own with them when they get a coffee .
According to the above context, choose the best option to answer the following question.
Question: Why is it a matter of concern that so many disposable cups are used ?
Options:
- There is only so much plastic to go around
 - None of the above choices .
 - People really do not like disposable cups
 - They are damaging the environment
