On April 22, 1970, millions of Americans took to the streets in a nationwide demonstration, giving birth to the modern environmental movement. The issues of concern three decades ago remain important topics today: oil spills, industrial pollution, and loss of wilderness and biodiversity, just to name a few. However, the possibility of global climate change was largely unknown in 1970, and it has only recently grabbed the international spotlight as one of the most serious environmental threats of the 21st century. Not surprisingly, the theme of Earth Day 2007, to be celebrated this Sunday, is "A Call for Action on Climate Change."
Small Changes Make Big Differences
Each year on April 22, Earth Day represents an opportunity for personal and global change. Although combating global warming may seem daunting to the average person, there are many simple ways to reduce carbon dioxide emissions and have a significant cumulative effect at the global level. For example, replacing all your household lights with energy-saving compact fluorescent bulbs will save 500 pounds of CO2 per bulb per year while also reducing your energy bill. Make a pledge to change your bulbs at the Earth Day Network.
