This document discusses various facts about our universe, solar system, and planet Earth. It notes that the universe is around 13.78 billion years old and contains at least 100 billion stars. It also describes our sun as accounting for 99.86% of the mass in our solar system, and notes that 90% of stars are smaller than our sun. Additionally, the document discusses the significance of human-caused climate change and its effects on factors like temperature, sea levels, and forest cover reduction.

Temperature change in about 100 years?!
By 2030 nearly half the global population could be facing
water scarcity. Demand could outstrip supply by 40 per cent

11. The human impact on
climate during the industrial
era greatly exceeds that due
to known changes in natural
processes, such as solar
changes and volcanic
eruptions……..
Human Activities affect Climate change

12. Human Activities affect Climate change

13. Climate change affect on Sea Levels

14. Forest cover reduction

15. A 2013 study on non-smokers has found that Indians have 30% lower lung function
compared to Europeans.
2013 Environmental Performance Index ranked India 155 out of 178 countries
In cities like Bangalore, around 50% of children suffer from asthma
India was the third largest emitter of carbon dioxide in 2009 at 1.65 Gt per year, after
China (6.9 Gt per year) and the United States (5.2 Gt per year).
The Global burden of disease study for 2010, published in 2013, had found that outdoor
air pollution was the fifth-largest killer in India and around 620,000 early deaths
occurred from air pollution-related diseases in 2010.
According to a WHO study, 13 of the 20 most-polluted cities in the world are in India;
however, the accuracy and methodology of the WHO study was questioned by the
Government of India led by Manmohan Singh.
