Read the article. What is the problem Boyan Slat is trying to solve? What is his solution?

There are very few people who come up with a world- changing idea during their lifetime - but to come up with it while you are still a student is even more unusual. But that is exactly what Dutch teenager Boyan Slat has done. Environmental Impact magazine interviewed him.

EIM: What is the problem that you identified?

BS: Every year, millions of tonnes of plastic end up in the oceans, where the waves break it up into tiny pieces. This pollution kills millions of sea creatures every year.

EIM: Hasn't there been any action to stop it?

BS: Very little, even though campaigners have been calling for it for years.

EIM: And you've worked out a way to tackle the problem.

BS: Yes. My invention would float on the surface of the ocean and gradually clean it up by collecting around 20 billion tonnes of plastic from the water.

EIM: What would you do with all that plastic?

BS: Rather than throwing this away, it could be recycled and sold for about $500 million a year.

EIM: And how would your floating invention be powered?

BS: It would take energy from the waves and sun, so it would never run out of it!

          Experts in climatology and other scientists are becoming extremely concerned about the changes to our climate which are taking place. Admittedly, climate changes have occurred on our planet before. For example, there have been several ice ages or glacial periods.
          These climatic changes, however, were different from the modern ones in that they occurred gradually and, as far as we know, naturally. The changes currently being monitored are said to be the result not of natural causes, but of human activity. Furthermore, the rate of change is becoming alarmingly rapid.
          The major problem is that the planet appears to be warming up. According to some experts, this warming process, known as global warming, is occurring at a rate unprecedented in the last 10,000 years. The implications for the planet are very serious. Rising global temperatures could give rise to such ecological disasters as extremely high increases in the incidence of flooding and of droughts. These in turn could have a harmful effect on agriculture.
          It is thought that this unusual warming of the Earth has been caused by so-called greenhouse gases, such as carbon dioxide, being emitted into the atmosphere by car engines and modern industrial processes, for example. Such gases not only add to the pollution of the atmosphere, but also create a greenhouse effect, by which the heat of the sun is trapped. This leads to the warming up of the planet.
          Politicians are also concerned about climate change and there are now regular summits on the subject, attended by representatives from around 180 of the world’s industrialized countries. Of these summits, the most important took place in Kyotoin Japanin 1997. There it was agreed that the most industrialized countries would try to reduce the volume of greenhouse gas emissions and were given targets for this reduction of emissions.
          It was also suggested that more forests should be planted to create so-called sinks to absorb greenhouse gases. At least part of the problem of rapid climate change has been caused by too drastic deforestation.
          Sadly, the targets are not being met. Even more sadly, global warnings about climate changes are often still being regarded as scaremongering

Greenhouse gases cause the warming up of the Earth because they _______.

A. are emitted by car engines

B. trap heat from the sun

C. do not add to atmosphere pollution

D. are unusual gases
