Global warming- Let’s celebrate April 1 as Cool Day!

In our quest for development that has meant urbanization, defense up gradation, agriculture and industrialization we have fooled ourselves every day as we have chosen a path of self destruction. Modern day development has come at a huge cost of environment. Increase in atmospheric temperature is one of the serious byproduct of modernization. Sixteen of the seventeen warmest years on record have occurred since 2000. Researchers maintain that if global warming continues, summers in India could last for 8 months by 2070. Global warming is rapidly killing the healthy environment. Scientists agree that the earth’s rising temperatures are fueling longer and hotter heat waves, more frequent droughts, heavier rainfall, and more powerful hurricanes. Development is one thing that we all desire, we won’t like to compromise on that; global warming can be stopped only by planting trees. We all need to act now to give our next generation a good and healthy environment.

Deforestation results in global warming. Deforestation is clearing Earth’s forests on a massive scale, often resulting in damage to the quality of the land. Forests still cover about 30 percent of the world’s land area but India has less than the world average forest cover- a 21.23% land under forest cover. Not all deforestation is intentional. Some is caused by a combination of human and natural factors like wildfires and subsequent overgrazing, which may prevent the growth of young trees. Deforestation also drives climate change. Forest soils are moist, but without protection from sun-blocking tree cover, they quickly dry out. Trees also help perpetuate the water cycle by returning water vapor to the atmosphere. Without trees to fill these roles, many former forest lands can quickly become barren deserts. Removing trees deprives the forest of portions of its canopy, which blocks the sun’s rays during the day, and holds in heat at night. This disruption leads to more extreme temperature swings that can be harmful to plants and animals. Trees also play a critical role in absorbing the greenhouse gases that fuel global warming. Fewer forests means larger amounts of greenhouse gases entering the atmosphere—and increased speed and severity of global warming.

Planting trees help the environment, reduces global warming. According to the environmental protection agencies, planting trees is a must if we want to save our planet. Trees not only remove harmful chemicals from the soil, but also help reduce the greenhouses leading to global warming. Go on and see how planting trees helps the environment.

An average size tree creates sufficient oxygen in one year to provide oxygen for a family of four. Planting trees in the right place around buildings and homes can cut air-conditioning costs up to 50 percent. Planting trees for the environment is good as they are renewable, biodegradable and recyclable. If we plant 20 million trees, the earth will get with 260 million more tons of oxygen. One acre of trees can remove up to 2.6 tons of Carbon Dioxide each year. During photosynthesis, trees and other plants absorb carbon dioxide and give off oxygen. Trees keep in cheek the air and water pollution. Why planting trees is important is evident as they are the natural habitat of the animals and birds, as well as many endangered species. Planting trees means more wood and paper products which can be easily recycled. A newly planted whole forest, can change tones of atmospheric carbon into wood and other fibrous tissue, thus reducing global warming.

It’s time to start celebrating April 1 as Cool Day. Worldwide, trees are often planted to help control temperatures and mitigate the effects of the “urban heat island”. Trees have been called “nature’s air conditioners”. Most obvious way to measure the cooling effect of trees would be to compare the air temperature in parks with that in nearby streets. Trees can help provide cooling in two ways: by providing shade, and through a process known as evapo-transpiration. Locally, trees provide most of their cooling effect by shading. How warm we feel actually depends less on local air temperature, and more on how much electromagnetic radiation we emit to, and absorb from, our surroundings. A tree’s canopy acts like a parasol, blocking out up to 90% of the sun’s radiation, and increasing the amount of heat that we lose to our surroundings by cooling the ground beneath us. Trees can also cool down buildings – especially when planted to the east or west – as their shade prevents solar radiation from penetrating windows, or heating up external walls.

Let each one: plant one. If all residents plant one tree on this day and take a pledge to take care of the plant till it becomes self sustaining in 1-2 years we can save mankind from destruction. Let government also start a campaign on the similar lines like SWACHH BHARAT. The new project can be called as GREEN BHARAT. Let each one: guard one tree. It’s time to adopt the orphan trees! Let each one of us adopt an existing tree, post our photographs holding our voter cards by the side of trees thus adopted and give a clear message of adopting the orphan trees on social media so that our vote minded leaders think a hundred times before giving nod to tree felling.

If  we Indians start planting trees and preserving existing ones, happy days will be here again very soon.
