Urban areas are usually densely populated locations. People migrating from villages towards cities further increase the population burden of cities. Thus urban areas are suffering from serious congestion and traffic problems. Here is a case of Ranchi.
Ozone absorbs ultraviolet radiations so that much of it is never allowed to reach to the earth surface. The protective umbrella of ozone layer in the stratosphere protects the earth from harmful ultraviolet radiations. Ozone plays an important role in the biology and climatology on the earth’s environment. It filters out all the radiations that remain below 3000Å. Radiations below this wavelength are biologically harmful. Hence any depletion of ozone layer is sure to exert catastrophic impacts on life in the biosphere.
Anything from which we can derive energy is called as a source of energy. Since all the life processes need energy, energy is most important for our survival.
Our body derives energy from the food we eat. Thus, the food we eat is the source of energy for our body. But this is not the whole story. We need energy for our growth and economic development as well.

Interdependence between two species through which individuals of either one or both species benefit is called positive interdependence. The benefits to the individual of any species through this relationship may be continuous or transitory, obligate or facultative. Both partners in this type of relationship may be in close contact; one may be inside some specific area or attached to the surface of the other’s body. Positive interdependence is divided into three major types: mutualism, Commensalism, and proto-cooperation.

The dry weight of organic matter produced by plants, their derivatives and wastes are called as BIOMASS. The biomass includes crop residues, plant parts, body parts of dead animals and animal wastes. As biomass is created due to photosynthesis by plants, so energy from biomass or bio wastes is regarded as another form of solar energy.
