How do we solve the plastic catastrophe?

If the current trend of pollution continues - scientists predict by the year 2050, there could be more plastic in our oceans than fish. That is an extraordinary prediction.

Now, more than 40 large companies in the UK have signed up to an agreement.

The aim: to eliminate single plastic use or packaging that cannot be reused. The goal: to do it in the next seven years.

The move is a first and the decision is expected to be followed by companies in other countries.

Now, a million plastic bottles are purchased every minute in the United States alone.

And approximately 500 million straws are used and discarded in that country every day. For coffee lovers in Britain, perhaps this figure will give you a jolt: 2.5 billion disposable coffee cups are used each year.

So, what can companies and governments do to encourage plastic recycling?
