Modern humanity is greatly endangered by the environmental changes that have taken place because of development and progress. Industrial development gave place to the expansion of cities and towns accommodating millions for running various industries. But this expansion and development has proved costly to mankind all over world. Man has become a victim of his own doing. Cutting down trees led to forests becoming arid deserts suffering from floods or droughts. The natural surroundings became weak in sustaining man on this planet. Not to say that animals, insects and worms too became victims as they were looted of their habitation.
Man did not stop here and did not spare the rivers and seas. Purity of water has been marred by the dirty water of factories and sewerage. Rivers and seas are badly polluted on account of developing habitation units. The rivers and their water have turned into a health hazard.
An average increase in the Earth’s temperature, which in turn causes changes in climate, is known as global warming. It leads to a wide range of impacts on plants, wildlife, and humans. Greenhouse gases like carbon dioxide (CO2), halogenated fluorocarbons (HCFCs), carbon monoxide (CO), nitrous oxide (N2O), ozone (O3), per fluorinated carbons (PFCs), methane (CH4), and hydro fluorocarbons (HFCs) make the Earth warmer by trapping heat inside the atmosphere.
The number of human activities and products that contribute to global warming are so numerous that finding solutions to the problem is very difficult. Due to the increase in population a greater number of people consume more items which takes up more energy. All these factors increase the global warming problem. Various activities, for example using a refrigerator, release dangerous gases into the atmosphere; turning on the electric appliances requires energy from a power plant, and driving a vehicle to work releases harmful emissions from the car leading to global warming. Since most of these gases are produced by important and common processes, limiting their production would be difficult. As population increases and the next generation would have to use greater amounts of energy, and the problem may expand even further.
The climatic changes that take place as a result of global warming are extremely difficult to predict. If temperature rises significantly, its impact would be on some portion of the Earth. The polar icecaps would melt, resulting in raised global sea levels and that would be catastrophic for low – altitude places. Islands would disappear, thus dislocating the millions of people who live there. Floods may occur along coastlines all over the world, displacing more people and ruining cropland. Global warming, if uncontrolled, could cause a major catastrophe. Spreading awareness through education is a key method of reducing the greenhouse effect. By teaching people about such things as deforestation and its impact on the society can help in curing this problem.
As the media pays more attention to this global warning problem, it helps increase awareness about the same across the world. This is prompting both individuals and governments to act more responsibly towards the environment. Family planning services actually help in the fight against global warming as it would help in limiting the population. Raising fuel prices, taxation, and encouraging people to take environmentally friendly actions through such activities as planting trees will all help.
