Teaching the Environmental Education
Teaching of environmental education is rather different. In involves practical experiences. For this both indoor and outdoor studies are essential.It also involves parents and community
Overpopulation and its impact
A group of individuals of a particular species occupying a particular area at specific time is called as population. A species is a group of similar type of organisms that can interbreed under natural conditions. The interbreeding organisms of a species produce new organisms and finally result into the growth of population. This is true for all the life forms including human beings.
Post Stockholm Developments
Environment and its components like wildlife and Natural Resources constitute the vital life support system for all life on this planet. The protection of these through the cumulative efforts of the world community started across globe due to the persistent efforts of the United Nations through its Environmental Programme (UNEP).
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.
Environmental Problems and their global perspective
Our environment today is facing a number of problems. All those problems are causing dangers to take shape against the existence of the whole biosphere of this planet. But who is behind all those problems? The answer is – M A N.
What is Global Warming and how is it linked to Green House Effect?
Human activities of pollution are modifying the natural process of green house effect. The advent of the Industrial Revolution in the 1700s boosted up the activities of burning of fossil fuels like coal, oil and natural gas which released lots of heat absorbing gases into the atmosphere.
Animal Shelters
An area or structure that protects animals from adverse conditions is called an animal shelter. Different kinds of animals need different types of shelters. Different kinds of animals and their shelters are mentioned here.
Kinds of animals and their shelters
Animals can be classified into terrestrial, arboreal, aquatic and amphibians.
Terrestrial Animals
Land animals are called as terrestrial animals. Some of these animals like lion, tiger, bears and bats live in rock caves. Illustration
Snakes live in ground, under rocks and in abandoned ant hills. Some snakes live insid
International legal regimes: on trade and environment
The Environmental Calamities that shook the humanity during fifties and sixties were powerful enough to generate serious and widespread sense of responsibility among world nations towards the global environment. Some of these calamities include : The killer smog in New York and London which claimed 5000 lives in 1952; The mercury poisoning due to the consumption of mercury-contaminated seafood in Japan;
Basic Concept of Biodiversity
Vast variability exists in the distribution or occurrence of different life forms in different habitats. The variability of life forms in a particular habitat is considered as the biodiversity of that habitat.
Impact of Human Activities on Environment
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.
What is Ecosystem? What are its components?
The environment of our earth has a number of life zones that support birth and development of all types of organisms.
All the life zones of the earth are collectively called as Biosphere.
The biosphere vertically extends into the atmosphere up to about 10 km and downwards into the oceans up to a depth of about6.9 km.
