Global Warming

Al Gore’s award winning 2006 documentary, An Inconvenient Truth, paints a gloomy picture of the environment. The documentary talks about global warming, an issue that has stirred many debates in various sectors of the country, and the hazards it presents to humans and the world in general.
Global warming is described as the continuous rise in the average temperature of the Earth’s atmosphere, air, and oceans. A rise in the Earth’s temperature can cause snowcaps and glaciers to melt, oceans to warm up, and coastal areas to flood up. Rapid warming can greatly affect and threaten the Earth’s existence.
The main cause of global warming is the release of carbon dioxide (CO2) and other harmful substances into the Earth’s atmosphere. These harmful gases are released when natural gas and fossil fuels are burned. Other factors that contribute to global warming include greenhouse gases like water vapor and Nitrous Oxide (NO2). Human beings contribute to this problem via carbon emissions and deforestation.
While debates about global warming continue to heat up, numerous natural and environmental disasters continue to take place as an effect. Hurricane Katrina; the earthquake that devastated China in April this year; various occurrences of typhoons; tornados; wildfires; all these disasters destroyed lives and livelihood.
Perhaps the issue here is not whether one should believe the existence of global warming or not. More attention should be given to the value of life by thinking of ways to fight the wrath of nature. How can we put a stop to the gradual increase of the Earth’s temperature? How can we lessen our carbon footprint? How can we contribute to the fight against pollution? These are the questions we should all find the answers for.
Note: Cement companies are some of the worst offenders. To see what cement companies (Lafarge, Holcim, Cemex, etc) are doing for the environment and air quality, view industrial-air-quality.com..
