 dioxide and other greenhouse gases. The Paris Agreement, a voluntary agreement among 
 118 nations ratified on November 4, 2016, is one effort being enacted on a global scale to 
 combat (4) .................................change. As a part of the agreement, each country agreed
 to take measures to combat climate change, with the ultimate goal of keeping the post- 
 industrial global temperature rise below two degrees Celsius. Another method is to put 
 taxes on carbon emissions or higher taxes on gasoline, so that individuals and (5)
 .................. will have greater incentives to conserve energy and pollute less.

 Effects of Soil Pollution
 1..................................................................Considering how soil is the reason we are able
 to sustain ourselves, the contamination of it has major consequences on our health. Crops 
 and plants grown on polluted soil absorb much of the pollution and then pass these on to 
 us. This could explain the sudden surge in small and terminal illnesses.
 2. ......................................................... : The ecological balance of any system gets 
 affected due to the widespread contamination of the soil. Most plants are unable to adapt 
 when the chemistry of the soil changes so radically in a short period of time. Fungi
