Read the following passage and answer the questions below it.
Microplastics are small pieces of plastic less than five millimetres in size. Some microplastics are manufactured, such as the microbeads added to health and beauty products, while others result from larger plastics gradually breaking down. These plastics are pervasive in marine environments, and they are known to harbour toxic substances such as heavy metals and phthalates.
Since many animals are known to eat microplastics, scientists are concerned about the toxic substances contained within them, as well as their capacity to accumulate within the animals and stop them from absorbing nutrients correctly.
Even the largest marine creatures are vulnerable to tiny fragments of plastic littering the world’s oceans. A new study has found whales and whale sharks – the largest fish in the world – are ingesting microplastics in alarming quantities. These creatures are filter feeders, meaning they consume large quantities of small prey by straining them out of the ocean water. In the process, they swallow hundreds to thousands of cubic meters of water daily, meaning there is the potential for them to take in substantial amounts of microplastic floating in the water.
Recently, plastic pollution has received a lot of attention for its effects on marine animals. In the UK, microbeads have been banned, and other plastic items such as water bottles and disposable coffee cups have also been in the firing line. However, while scientists agree that plastic pollution is a problem for marine animals, there is still a lot they do not know about the magnitude of its impact.
Are the following statements true, false or not given?
1) Harmful microplastics are widespread in the world’s oceans and seas.
2) Larger fish are the most likely to be harmed by these toxic plastics.
3) The only fish that ingest microplastics are those that swallow water.
4) Water bottles and disposable cups have been banned in the UK.
5) Scientists are yet to discover how serious the microplastic problem is.
