Evaluate one mitigation strategy to prevent a non-communicable disease in a developing country.

It can be argued that mitigation strategiess nay have been successful for non communicable diseases such as cancer in India. 99% of India's 1.2 billion people breathe in air that is polluted above safe levels. This could severely injure one's health as the tiny air-borne particles smaller than 2.5 micrometers can penetrate deep into one's lungs causing bronchitis and lung cancer. This could drastically reduce a person's life expectancy. However, to reduce air pollution levels in India, the Indian government has invested large sums of revenue on building rapid transit metro systems in 14 cities. Although air pollution is inevitable in a rapidly growing economy like India, tightened standards to reduce vehicle emissions can not only reduce India's pollution levels but global emission levels too. Furthermore, other national efforts to reduce NO^2 and SO^2 emissions include the retro-fitting of brick-kilns to reduce smoke emissions. This will reduce the contribution of CO^2 which can then improve life expectancy as fewer will inhale the smoke. Policies devised at the global scale to tackle climate change can be arguably said to have been successful. There are currently no regulations for emissions of NO^2 and SO^2 yet, prevalance of lung cancer is increasing due to India's development and urbanization. In addition to this, India is still a developing country and such investments may seem too ambitious which may suggest a time lag before any of the policies are actually implemented. By then, pollution levels may not be controllable.
