Every year on April 22, over a billion people in 190 countries take action for Earth Day, including right here in the Dallas-Fort Worth Metroplex. You might not be as familiar with Earth Day as some of the larger national holidays such as Independence Day, Memorial Day, or Presidents Day; but protecting and celebrating the Earth is very important! Like Earth Days of the past, Earth Day 2014 will focus on the unique environmental challenges of our time. As the world’s population migrates to cities and our climate continues to change, the need to create sustainable communities is more important than ever. The first Earth Day was officially celebrated on April 22, 1970 on the heels of the hippie and flower-child culture in the United States and rising air pollution from industries which had little or no fear of legal consequences or bad press. At the time, most Americans remained oblivious to environmental concerns and the smell of air pollution was more closely associated with prosperity than contamination. On the first Earth Day, 20 million Americans took to the streets, parks, and auditoriums to demonstrate for a healthy, sustainable environment in coast-to-coast rallies. Thousands of colleges and universities organized protests against the deterioration of the environment. Groups that had been fighting against oil spills, polluting factories and power plants, raw sewage, toxic dumps, pesticides, freeways, the loss of wilderness, and the extinction of wildlife suddenly realized they shared common values. As 1990 approached, a group of environmental leaders asked Denis Hayes to organize another big campaign. This time, Earth Day went global, mobilizing 200 million people in 141 countries and lifting environmental issues onto the world stage. By the turn of the new millennium, over 5,000 different environmental groups in a record 184 countries around the globe were celebrating Earth Day. The fight for a clean environment continues to our world of increasing climate change and a growing awareness for the importance of protecting our home. “One method of ensuring your air conditioning unit is earth-friendly is by choosing to use an environmentally safe refrigerant. Several air conditioning units use a refrigerant known as R-22 which is safe and effective when sealed within your system, but can be cause major ozone depletion in the event of a leak. Many of our systems now offer a much safer and improved refrigerant known as Puron or 4-10 A. Ensuring that your air conditioning system uses Puron as a refrigerant is an easy step towards being proactive in the fight to keep our earth pure and clean.” Your friends at Spencer Air Conditioning and Heating promote environmental responsibility with energy efficient air conditioning systems and provide plenty of other tips for keeping your house comfortable without wasting energy.
