• Carbon dioxide acts as a green house gas as its nature is to trap more and more heat which increases the temperature and hence considered green house gas
• Argon is used to fill electric bulbs as it is a noble gas.
• CFC's should not be used in refrigerators or AC machines as it is harmful and cause global warming
• Tall chimneys with filters to be used in factories to avoid carbon Dioxide and monoxide emissions in air this causing air pollution.
• Plantation is required more and more in our surroundings to reduce air pollution as plants absorb carbon dioxide and release Oxygen.
