A wetland is an ecosystem that is occupied by water, either permanently or seasonally. The wetland is occupied with water from rain, agricultural irrigation, water from the streams of water sources like river, lakes and ponds. Smog is a kind of air pollution, that develops from the mixture of the smoke and fog present in the air. A smog is formed by the burning of the coal, mixture of the smoke and sulfur dioxide.  

A wetland has no influence on the formation of the smog, but if a wetland gets wiped out due to drying or because of any other reason it may result in the loss of habitat of the organisms living in the wetland, flooding can occur if the water in the wetland rises, the water from different sources accumulated due to surface runoff can contain unfiltered water.  

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.
