Question

construction of large dams submerges large areas of forests how does this contribute to the greenhouse effect

Answer 1

construction of dams submerge large areas of forests. ... Construction of large dams leads to the production of green house gas and thus they may contribute to changes in the climate of Earth. For instance, warm climate dams or reservoirs produces methane gas which is a greenhouse gas.

When dams are built large areas of forests are submerged. When this submerged vegetation undergoes anaerobic respiration, it releases gases like methane and CO2 which are greenhouse gases. Thus it contributes to greenhouse effect.
