By damming rivers and creating reservoirs, we are . By damming rivers and creating reservoirs, we are . increasing transportation decreasing evaporation increasing evaporation decreasing transpiration increasing transpiration while decreasing evaporation

Explanation:

Rivers are flowing water body . So it is used for transportation. Rivers , canals etc are very cheap means of transport . They are environment friendly too because we do not have to burn fuel in carrying luggage through rivers. By damming rivers , we are actually decreasing means of transport. Rivers are blocked due to deposit of eroded soil which decreases flow of water . So our waterways are destroyed.

reservoirs are stagnant water bodies . They play an important role in the process of evaporation which stimulates rainfall . The larger the reservoir , the larger the process of evaporation .

i think the answer is tomato juice? not entirely sure though
