Respostas
1) Para responder o problema proposto vamos primeiramente encontrar o texto o qual não foi apresentado. Assim, com o texto em mãos vamos responder o problema proposto com base no assunto sobre cada questionamento. Logo, teremos:
a)Human health :
The human health can be linked with climate change and well-being in many ways, including impacts from increased extreme weather events, wildfire, decreased air quality, and illnesses transmitted by food, water, and diseases carriers such as mosquitoes and ticks. All of human can be impact by several changes that us different from normal.
b)Air pollutant from human activity :
Air pollution can be linked to human misbehavior related to burning, deforestation and a high amount of oil products.
c)Urban and rural communities :
The rural community differs from the urban one in that they use less activities involving the burning of CO2 that directly impacts air quality.
d)Energy and air pollution how are they linked?
Power generation and air pollution are linked by the fact that there are power generation systems that promote air pollution. With for example coal plants.
Para realizar a tarefa, precisamos primeiramente ler o texto "Energy and air pollution - How are they linked?".
Depois disso, precisamos escrever as ideias principais do texto sobre:
1) Human health
According to the text, the fourth greatest overall risk factor for human health worldwide is the air polution. It comes right after high blood pressure, dietary risks and smoking. Sulfur oxides, nitrogen oxides and ozone are associated with a range of illnesses, and fine particulate matter is the most damaging to human health. Air pollution poses risks to the environment, the economy and food security. Human health can be linked with climate change with the impacts from increased extreme weather events, wildfire, decreased air quality, and illnesses transmitted by food and water, and also disease carriers.
2) Air pollutant from human activity
The consumption of biomass, kerosene and coal in the buildings sector, along with industrial use, are responsible for the bulk of the particulate matter reaching the atmosphere. Air pollutants arising from human activity overwhelmingly derive from energy production and use, mainly the combustion of fossil fuels and biomass. In the energy sector, power generation and industry are the main sources of sulfur dioxide, and the oil used in vehicles and power generation are the leading emitters of nitrogen oxides.
3) Urban and rural communities
The poor air quality is often regarded as an urban problem, what can be explained by the concentration of people, the economic activity and energy demand in the world’s growing cities. The poor air quality also affects many rural communities, particularly where households continue to rely on solid biomass for cooking and kerosene for lighting. Besides that, the major pollutants, including secondary pollutants formed by chemical reactions in the atmosphere, can be transported large distances from their sources. The rural community can differ from the urban one because they use less activities involving the burning of CO2 that directly impacts air quality.
4) Energy and air pollution, how are they linked?
The energy sector is linked with the air pollution because it is the predominant source of air pollution, and it must be at the forefront of action to improve air quality around the world, which a range of proven policies and technologies are available to do so. Regulations have helped to achieve a major drop in emissions in some sectors in the US, Japan and in European Union. Improvements in air quality are becoming an increasingly urgent policy priority in many Asian countries because pollutant emissions have risen in line with very rapid growth in energy demand seen in recent years. So, no jurisdiction can claim that the task of tackling air pollution is complete.
