Following are the correct options for this question:
- Build more windmills
- Develop cost-efficient solar energy
- Improve gas mileage in cars
- Reduce the use of nonrenewable energy sources
Any undesirable change occurs in the air due to addition of pollutants is called air pollution. The major air pollutants are sulfur dioxide which is released from the combustion of fossil fuels like coal, petroleum and from factories. Bedsides, sulfur dioxide dust and smokes are other pollutants. Building of more wind mills and developing low cost solar energy will reduce air pollution as they will provide clean energy and will reduce dependency on coal burning in thermal power plant. Improving as mileage in cars will also reduce emission of sulfur dioxide, hence reduce air pollution. Building of more wind mills and developing low cost solar energy are renewable source of energy, will reduce use of nonrenewable energy sources such as fossil fuels.
The percentage of languages that are dying out in Asia is only around 20% from the total number of languages dying out in the world, despite it having around 60% of the global population is due to two reasons:
- <em>Number of languages;</em>
Asia, even though it has around 60% of the world's population, it only has around one third of the languages spoken in the world, so automatically there's a big disproportion between the number of population and number of languages, thus giving it a smaller percentage of languages dying out.
- <em>Keeping the tradition;</em>
Lots of Asian nations are not very willing to let their traditional language to die out and continue to speak it. Apart from the traditional point of view, another reason is that Asia has global economic powers, so learning languages like the English or Spanish are not of great benefit in general, so the pressure is much lesser.
