Answer 1

Answer:

please make us brinnest

Explanation:

photosynthesis is the process used by plants, algae and certain bacteria to harness energy from sunlight and turn it into chemical energy. Here, we describe the general principles of photosynthesis and highlight how scientists are studying this natural process to help develop clean fuels and sources of renewable energy.

Answer 2

Pollution of air in 5 Metro cities of India :

• Air pollution in India is a serious health issue. Of the 30 most polluted cities in the world, 21 were in India in 2019.
• As per a study based on 2016 data, at least 140 million people in India breathe air that is 10 times or more over the WHO safe limit and 13 of the world's 20 cities with the highest annual levels of air pollution are in India.
• 51% of the pollution is caused by industrial pollution, 27 % by vehicles, 17% by crop burning and 5% by other sources.
• Air pollution contributes to the premature deaths of 2 million Indians every year.
• Emissions come from vehicles and industry, whereas in rural areas, much of the pollution stems from biomass burning for cooking and keeping warm.
• In autumn and spring months, large scale crop residue burning in agriculture fields – a cheaper alternative to mechanical tilling – is a major source of smoke, smog and particulate pollution.
• India has a low per capita emissions of greenhouse gases but the country as a whole is the third largest greenhouse gas producer after China and the United States.
• A 2013 study on non-smokers has found that Indians have 30% weaker lung function than Europeans.
• According to CPCB there are 593 stations operating under NAMP as on 30th June 2015 which are spread over 249 cities in 29 states and 5 union territories in India.

• Out of 249 cities covered under NAMP only 16 cities are providing data on air pollutants through online portal managed by CPCB.
• According to CSE, Amritsar, Aurangabad, Delhi, Faridabad, Jaipur, Kolkata, Meerut, Navi Mumbai, Pimpri-Chinchwad, Pune, Thane and Vijayawada are the hotspots for NOx pollution.
• NOx leads to the formation of secondary particulate pollution and cannot be filtered by air purifiers.

• The pollution levels in the Indian cities have increased due to surge in construction work, boom in industrial activity and sharp spike in use of vehicles.
• The Tier 2 and Tier 3 cities are not equipped to deal with this sudden rise in pollution and have poor air quality monitoring systems.
