Contribute something important to the nation’s well-being.

Almost everyone loves trees, but did you know that trees can help people heal faster? It’s true. According to the International Society of Arboriculture, hospital patients have been shown to recover faster when offered a view with trees. And while trees certainly benefit any landscape i.e. whether lining residential streets, dotting urban areas, or in full resplendence in the forest, they are actually important to our daily well-being.

It goes without saying artificial beauty is nothing in front of the natural beauty. Natural Attractions cannot be replaced by the man-made artifacts and one cannot extract that pleasure from the artificial things, which one could get from the natural creations.

Pakistan’s capital Islamabad is known by its greenery and serene atmosphere, but would it be so after couple of years? Its hard to say. Swarm of traffic has compelled Capital Development Authority (CDA) to develop more roadways, and widen the existing road network. Its a good thinking, but the price is quite high.

One billion personal computers have been sold across the world, according to hi-tech consultancy Gartner Dataquest report. The number of computers is set to explode in the next few years, reaching the two billion mark by 2008. Unprecedented technology growth in deed! But this is not about the technology growth. Point here is how computer can help save the trees.

Two main environmental issues in the world today are global climate changes and local or regional air pollution. Both are results of energy consumption all over the world.

Responses to the energy usages are important to the entire planet and its inhabitants. Current and future policies and regulations designed to limit the emissions of airborne pollutants, where ever they are in place, are likely to affect the composition and growth of global energy use.

Mobile (transport) and stationary energy (industry) consumption have resulted in increasingly stringent regulation of air pollutants such as lead, sulfur oxides, nitrogen oxides and volatile organic compounds deteriorating the environmental and air quality in the process.

Acids that fall out of the atmosphere are called Acid Rain. Airborne acidic pollutants have highly destructive results. Acid rain is defined as a “rain with a pH of below 4.0 – 4.5.” Normal rain has a pH of about 5.6, which is slightly acidic (In chemistry, pH is a measure of acidity). Acid rain was fist discovered in 1852, when the British chemist Robert Agnus invented the term.

Human beings like other organisms, have always polluted their environment with the byproducts of their action. As an organism man creates waste. As a social creature, he removes things from his environment and adds residue to it. So long as population density has been low on the planet, the environment was able to accommodate these alterations. Now with the world population about 8.5 billion people and increasing by 220,000 each day, the concentration of population in cities and resulting deterioration of environment is sounding alarms. The situation is urban Pakistan is worst.

Have you ever thought of bringing wildlife to your own home? It may be wonderful adventures to attract more birds, fireflies and or butterflies and so many other creatures to your own garden in courtyard, backyard or rooftop?

All wild species have four basic requirements for existence: food, water, shelter, and places to breed. Look around and one notices that the home garden, how small it may be, may already be providing habitat for some of the wildlife. Plants in the garden provide food in the farm of seeds, fruits, nuts, and nectar and or a nesting and breeding places to the birds? Even dead or dying trees (some time placed for decoration) are haunts for some species. They are excavated and used by woodpeckers, squirrels, and a multitude of insects and cavity-nesting birds, such as owls, bluebirds, chickadees, and wrens.

Environmentalists, naturalist and conservationists around the glob were particularly happy on the news that the Right Livelihood Honorary Award for the year 2004 recognized the outstanding services of Raúl Montenegro in different fields of environment. .

The Right Livelihood Award, commonly known as Alternative Nobel Prize, was established in 1980 to pay tribute to and help people in different fields of human activity and uphold the principles of right livelihood.

Planet Earth appears to be big with an endless ocean of air around. Astronauts see the planet as small dot set against black background with a thin layer of atmosphere. Environmentalists fear that our home planet is slowly scorching. Earth is the third planet from the Sun at a distance of about 150 million kilometers. It takes 365.256 days for the Earth to travel around the Sun and 23.9345 hours for the Earth to complete one rotation. It has a diameter of 12,756 kilometers. Atmosphere is composed of 78 percent nitrogen, 21 percent oxygen and 1 percent other element. About 71 percent of earth’s surface is covered by water and the rest is land.

There are over thousands of bird species on this beautiful planet. We see them flying, humming, singing, and dancing everywhere: in the air, in wilderness, in and around our homes. They are important part of ecological system and help sustain life on earth in so many ways.

Birds live happily in cleaner environment. But the environment is not cleaner. Besides migrations triggered by changes in light, temperature, and food availability, birds are often forced to migrate or worst still are killed due to human activities like deforestation, pollution and extensive use of chemicals. Birds have proven sensitive to many forms of environmental change, including chemical pollution, and are sometime used by scientists as an early warning for humans. This makes them excellent subjects to study for understanding ecological processes and environmental health.
