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.
We have many types of butterflies around us. These are good pollinators of crop plants and grass pollinators. Theecotrends lens has some images of these pollinators
The positive movements of a plant shoot in response to light or movement of shoot towards the source of light is called as Phototropism. If the part of a plant moves away from light, this movement is called as Negative Phototropism.
The acid rain affects living and non- living components of environment. In July 1982, Stockholm- the venue of U N –conference on acid rain, suffered heavy acid showers for about a week. In India too, acid rains have been reported since last twenty years in areas where thermal power plants are located and also around Delhi, the capital of India.

Our natural resources are known to have some specific qualities of their own. These qualities are known as natural qualities. It is due to specific natural qualities that different natural resources have been useful to us and to the whole biosphere. But now, the condition has changed considerably.
A population is a group of individuals of a particular species occupying a particular area at a specific time.
Growth of human population, fast but unplanned industrialization and irresponsible behavior to environment are causing imbalances in the local, regional, national and global environment. These are causing not only local but global problems in the environment.
