Green house effect is a process by which radioactive energy leaving a planetary surface is absorbed by some atmospheric gases called green house gases. This energy is transferred to other components of the atmosphere and is also radiated backwards. The mechanism of this effect is that the warmth is isolated inside the structure so that the heat is not lost. Green effect was discovered by Joseph Fourier in 1824. Global warming is the result of green house effect due to excessive emission of green house gases. This is also caused due to human produced increases in atmospheric green house gases.
The principle mechanism can be explained as follows. The earth receives energy from sun in the form of sunlight. Light is absorbed by earth's surface and re-radiated. The heat that is retained in earth's surface and lower atmosphere increases the temperature and results in global warming.
The four major green house gases are:
1. Water vapor
2. Carbon dioxide
3. Methane
4. Ozone
Strengthening of this condition through human activities is known as oranthropogenic. This increases carbon dioxide level in atmosphere and adversely affects the living things. Besides earth, Mars, Venus and the moon namely Titan exhibits effect. Global warming has been a threat since many years. Deforestation is one of the main causes as it increases amount of carbon dioxide level in atmosphere.
Even though people are aware of this phenomenon, there are plenty of them who act as though they are not aware of the depleting atmosphere of the earth. Thus they get involved into those practices which can certainly disturb the atmospheric balance. Some of the deeds include polluting the air, water and other resources, deforestation, using electronic good known to cause harm to our peaceful environment and so on. Therefore, it is very important to make the society aware about the bad effects and save our earth as well as ourselves.

Biogas Digesters Are Becoming Useful For Fuel By Chuck Cox
Biogas is a gas that is created whenever animal and plant wastes degrade. Bacteria ferment the waste under anaerobic, or oxygen-free, conditions. The result of this fermentation includes carbon dioxide and methane.
Methane is created in landfills, where the buried waste rots and produces this gas. Often, methane is permitted to escape into the atmosphere. However, it can easily be collected and piped to local industries where it could be available for burning to release heat along with other energy options.
Biogas could also be produced under more controlled conditions in pits in the ground or in tanks called biogas digesters. All types of human and animal waste can be put into these digesters. The rotting mass releases gases, such as methane, that can be piped away and burned as a fuel for heating and cooking.
This exciting energy source is becoming a major fuel source in many developing countries, where practically all rural families or villages can make use of a biogas digester to generate fuel. Biogas digesters are used on farms to dispose of animal wastes. The gas can be further used to power a generator to produce electricity. The intensive farming that is found in Denmark and the Netherlands generates large amounts of animal waste, which needs careful disposal. It is fermented in digesters to produce biogas, while the residue is used as crop fertilizer.
Elsewhere, household wastes, livestock waste, and poultry waste are burned in specially modified power stations, rather than used to make biogas. These power stations have to meet strict emission controls to prevent the release of toxic chemicals.
Of course, one additional benefit of burning off the methane from these waster sources is that it will help reduce greenhouse gases significantly.

Biotechnology - Fast Emerging Sector of India By Kamal Poria
Biotechnology is considered to be a quickly emerging and far-reaching technology. It's a branch of science that may play a major role in the development and growth of India. Biotechnology refers to any technological application that uses biological systems and forms in a governable manner, to not only produce new and useful processes or products but also modify the existing ones. It benefits both mankind and other life forms, such as microorganisms. Besides, biotechnology helps maintain an optimum ecological balance by lowering the amount of hydrocarbons and controlling pollution.
Biotechnology in India is one of the most rapidly growing knowledge-based sectors. Today, it's being increasingly used to design and develop unique, improved varieties of pharmaceutical products, crops, fertilizers, processed foods, a plethora of chemicals, cosmetics, growth enhancers, health care aids, and environment-related substances. The biotech segment in India has been making fast strides on the world platform. India is currently producing and marketing many therapeutic biotech drugs and vaccines. From 2005-2006, the Indian biotech sector recorded an impressive revenue of approximately US$ 1.07 billion and registered a 36.55% growth.
India has diverse biological resources. Biotechnology offers opportunities to convert these resources into employment opportunities and economic wealth. Several factors create an impetus for India to produce excellent capabilities in the domain of biotechnology. These factors include a strong pool of scientists and engineers, a large reservoir of scientific human resources, affordable manufacturing capabilities, numerous medical colleges, educational and training institutes providing diplomas and degrees in biotechnology, a large number of national research laboratories engaging thousands of scientists, fast developing clinical capabilities, and a vibrant drugs and pharmaceutical industry.
The Department of Biotechnology (DBT) in India is regulated by the Ministry of Science and Technology and is a top authority responsible for the development of the biotech industry. This department is responsible for planning, promoting, and organizing different biotechnological activities and programs in India. It also offers grants to universities, national research laboratories, and research foundations associated with biotechnology-related activities.
The key responsibilities of the DBT include:
1. Promoting large-scale use of biotechnology
2. Acting as a government agent for importing fresh recombinant DNA-based biotechnological processes, technologies, and products
3. Building infrastructure facilities to aid R&D and production
4. Initiating technical and scientific efforts associated with biotechnology
5. Promoting international collaborations to expound the knowledge base of the biotech sector in India
6. Providing bio-safety guidelines for laboratory research, applications, and production
7. Serving as a nodal agency for collecting and disseminating biotechnology-related information
Furthermore, the Indian government has set up the National Bio-Resource Development Board (NBDB) under the department to determine the broad-policy framework for efficient use of biotechnological research and development.
The key functions of this board include:
1. Promoting how bio-resources add value and strengthening bioinformatics
2. Formulating predictive groupings of biological resources via well-developed molecular lineages
3. Providing efficient conservation strategies for bio-resources with potential economic and scientific value
4. Promoting the application of biological software in pathogens' and agricultural pests' management
5. Training and teaching human resources towards achieving all these objectives
The Indian government is also establishing many biotech parks and incubators. Some existing biotech parks/incubation centers are in Uttar Pradesh, Hyderabad, Kerala, Himachal Pradesh, and Bangalore.
With so many measures being adopted to promote biotechnology, the Indian biotech sector is set to flourish, and it can revolutionize agriculture, industrial processing, health care, and environmental sustainability.

Anatomy 101 - The Human Body From a Kid's Point of View By Adam Singleton
The human body is something you'd think would be a natural object of understanding for humans, but not a huge number of people can boast knowledge of everything concerning these temples within which we live. Explaining it to children can prove difficult too - so what sort of things can you do to help your descriptions when those inevitable questions come along?
Children can be a lot smarter than we sometimes imagine. Many kids go through childhood experiencing various 'obsessions', where they find an interest and research it thoroughly; learning all there is to know about the subject. Take dinosaurs for example, which are always a popular interest. Most of us can probably think of at least one child who's been through the phase of reading up all about the giant lizards, collecting toys, watching the TV programmes, etc - if it's not us ourselves. This natural enthusiasm for learning is something that should be kept in mind - children, and humans in general, are inquisitive beings that thirst for knowledge. So it's important to latch onto this early and ensure kids get the most out of that early enthusiasm.
There are plenty of ways to encourage learning, such as books, DVDs, computer software and even plain old conversation. Children ask 'why?' a lot when growing up - and so do adults, albeit most of us do it quietly these days - and parents and teachers should capitalise on this inclination by telling them why, or how, or even what. What's more is that you'll probably get to enjoy it too.
A lot of the ways that kids learn stuff are usually fun. The books they read, the films they watch and even educational cartoons are designed to be amusing as well as instructive. This can make a welcome change from the slightly more stoic way of learning that grown-ups are used to, revisiting the basics in a bright and colourful manner that can prove entertaining as well. Opening up a book to help you teach your child about the human body can be a fun experience since children's literature is more about getting information across in an entertaining fashion rather than what comes across as quite inaccessible and stuffy by comparison in later years.
On top of all this, you spend time with the child, helping them to develop better social abilities whilst strengthening your own bond.
So what is there on the topic of the human body in particular? Depending on how old the child is, you could teach with anything ranging from rousing renditions of "head, shoulders, knees and toes" and the "hokey cokey" to question-and-answer sessions or reading books, watching television programmes and DVDs or using interactive CD ROMs or the internet.
There's a wealth of information out there concerning the human body, from your own personal knowledge to human body books - so don't feel restricted in what you can pass on as there's plenty of inspiration out there.
