About 1000 people died and nearly 175 000 people were made homeless. Winds reached 230 km / h and caused storm surges, which led to widespread flooding.

Person A: Before the hurricane, I lived in a shelter I had made myself. Lots of us lived like this. There were no building regulations. All the shelters were completely destroyed as soon as the hurricane started. I will have to build a new shelter. Person B: The roads into our village were destroyed by landslides and they were covered with flood water. No one came to help us for days. The country doesn’t have enough money to help everyone. Person C: I didn’t know what to do when the hurricane hit. No one had told us how to prepare. We had no mobile phone signal and all the power lines were down, so we had no idea what was happening. Person D: We lived outside for days. The only help we got was from a charity. They gave us plastic sheets for shelter and some food. Person E: Since the hurricane, a charity has given us early warning hurricane sirens. The maintenance of the solar-powered sirens is paid for by using them as charging stations for mobile phone users. © UCLES 2019 0680/12/F/M/19 9 (i) Do you think Haiti had an effective strategy for managing the impacts of Hurricane Matthew?

Before the mine opened, the United Kingdom imported the majority of its tungsten from overseas. The new mine will be the fourth-biggest tungsten mine in the world. The tungsten is found very close to the surface. There is an increased world demand for tungsten. The new mine created approximately 200 jobs in the local area.

[1] (d) A student read an article in a scientific journal about e-waste. E-waste E-waste consists of electrical and electronic equipment and their components, which have been thrown away rather than being reused. E-waste is difficult to manage because it is made-up of many different components, many of which are toxic. Typical toxins include heavy metals such as mercury, chromium and lead, acidic gases from burning plastics and CFCs from refrigeration units. These toxins can have negative environmental and health effects. Some e-waste contains useful metals such as tungsten, gold, silver, iron, aluminium and copper. Some countries have take-back systems where consumers can safely recycle their e-waste and even have their e-waste collected from their homes. However, most e-waste is incinerated, buried as land-fill or dumped illegally. (i) Describe what is meant by e-waste.

[2] (e) The article also contained some data about e-waste. The total global e-waste generated in 2014 was 41.9 million tonnes (Mt) and 50.0 Mt in 2018. In 2014, e-waste contained 1.00 Mt of lamps; 6.30 Mt of screens; 12.8 Mt of small electronic equipment; 3.00 Mt of small information technology items; 11.8 Mt of large electronic equipment and 7.00 Mt of refrigeration equipment. (i) Calculate the percentage increase in e-waste from 2014 to 2018. (8.1/41.9)x100= 19.3 % [2] ......................................................
