Dangerous Impact of Breaking of Mountains
Landslides are very common in rainy season. Rains caused serious conditions during previous some weeks this year in many villages of Maharashtra. Many of these villages that were located in the laps of mountains vanished within no time.
Heredity, Its Physical Basis and Variations
Some specific characters are found in the parents of each species. These characters are transferred from generation to generation through the process of sexual reproduction.
Habitat Destruction and Loss of Water Bodies
The predominant features that create structural complexity in the environment, such as plants or animals are called as a habitat.
A process, in which natural habitat is rendered functionally unable to support the plants and animals occupying it, is named as Habitat destruction. In the process of habitat destruction, plants and animals that previously used the place are displaced or destroyed, reducing biodiversity.
A Strange Bioinsecticide
Ladybird is one uncommon compound word made by the union of two simple common words – Lady and Bird. But, the two simple words when joined together can produce strange effect.
People’s Movements to protect forests
There have been a number of environmental movements in India through which people have been protesting for conservation of forests and other natural resources. Here some important People’s Movements have been introduced in brief.
Pollution of atmosphere
The condition produced due to ‘substances put into air by the activity of mankind into concentration sufficient to cause harmful effects to his health, vegetables, property or to interfere with the enjoyment of his property’ is called as air pollution or the atmospheric pollution
Modes of Reproduction
Two organisms- male and female are essential for sexual reproduction. Now let us study some basic methods of reproduction in single organisms.
Animal body parts and sense organs
Most animals of the same kind have same body parts. But their body parts differ in size, shape, colour and functions.
Our Food, Culture and Biodiversity
Thus, diversity of food is in fact the diversity of culture or at least you can say that cultural diversity of India is linked to its biodiversity. And so, the cultural diversity of the world is linked to its biodiversity. But often, we don’t get ready to accept it.
The emergence of environment problems and Sustainable World
The processes of development through years have spurred on unplanned urbanization, extensive industrialization followed by different types of pollutions, construction of a series of mega dams, and large-scale application of Agro-chemicals.
What is Ozone layer? How is it depleted and what are the control measures?
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.
