Environmental problems

Despite what the task asks for, I am about to explain the causes of all these natural disasters.

In the first picture I see a skull of something like a sheep. It's lying in a field, where there isn't any grass. This is the result of desertification. I consider that the main reason for desertification is the world's average temperature which is going up from year to year. Scientists call it the greenhouse effect.

In the second picture is a flood. This natural disaster becomes more and more common nowadays. Sometimes the reason for the flood is a hurricane, which has broken a dam. Another reason for the flood is a cyclone, which stays in the same place for a long time. Finally, if you are a citizen of a port city like Tokyo or Rotterdam, you could be a victim of a tsunami.

In the third picture I see a storm or hurricane. The speed of the wind is really high. A reason for the storm could be the mixture of warm and cold air.

Excellent! 

Though I think a tsunami hitting Rotterdam is a little unlikely...
