However, we seem to be unaware of one very dangerous pollutant, soot also called black carbon.1.________	Soot comes from the incomplete combustion or coal, oil, wood and other fuels. In other words diesel engines, vehicle exhaust pipes, farming machines, construction equipment, or simply fires in grills, fireplaces, and stoves are potential sources of soot. It appears in our daily life and can easily affect every one of us.c. The origin of sootcomes from appears2._______	Soot like all black things absorbs sunlight and heats up the atmosphere. According to recent research, it is the second most damaging greenhouse gas after C02, and twice as harmful to the climate. Although black carbon remains in the atmosphere for no more than seven days it is particularly damaging to frozen areas. Soot emissions might be responsible for the quick melting of the Arctic. Controlling black carbon can help to slow down global warming.a. Soot and global warmingControlling black carbon can help toslow down global warming.3._______	Soot does not only have an impact on global warming and climate change, but is also unhealthy. A soot particle is very tiny - smaller than dust and mould, and about 1/30 the width of a human hair. It can easily go into our bloodstream and lungs via the nose and throat. As a result, breathing in the tiny particles can cause asthma attacks, heart disease, bronchitis and many other respiratory illnesses.b. The effect of soot on human healthunhealthy.cause asthma attacks, heart disease, bronchitis and many otherrespiratory illnesses.4._______	Large quantities of man-made soot enter the atmosphere every year. The effects are most damaging regionally, especially in South and East Asia, Latin America and parts of Africa. In developing countries, reducing soot emissions can be achieved by replacing traditional stoves with clean, alternative fuel cookers and heaters. Installation of filters to remove black carbon from diesel vehicles can also reduce soot. Changing to electric or hydrogen vehicles will also reduce the impact on the environment.In conclusion, reducing black carbon will have immediate benefits in slowing down global warming and the melting of the Arctic snow and ice. It would also prevent many soot-related deaths and illnesses.d. Ways to reduce soot emissionsreducing sootemissions can be achieved byActivity 3: Complete the sentences with no more than 5 words. 1.
