Natural gas is important in many sectors of the economy: for generating electricity, as a heat source for industry and buildings, and in chemical feedstock. Despite its vital importance to the economy, natural gas has often been overlooked, or at best taken for granted, in the debate about the future of energy.

Over the past two or three years, this has started to change, and natural gas is finding its place at the heart of the energy discussion. Given the abundance of natural gas available through extensive global resources and the recent emergence of substantial unconventional supplies in the United States and discovery of new sources in some countries, worldwide usage of the fuel is likely to continue to grow considerably and contribute to significant reductions of greenhouse gas emissions for decades to come, according to a comprehensive, multidisciplinary study carried out over the last three years by MIT researchers... 

Mother Earth is a common expression for the planet earth in a number of countries and regions, which reflects the interdependence that exists among human beings, other living species and the planet. For instance, Bolivians call Mother Earth Pachamama and Nicaraguans refer to her as Tonantzin. In 2009, the United Nations designated April 22 International Mother Earth Day.

Earth Day is a day that is intended to inspire awareness and appreciation for the Earth's natural environment. Earth Day was founded by United States Senator Gaylord Nelson as an environmental teach-in first held on April 22, 1970.

From then the not-so-humble beginnings in 1970, when 20 million participated across the U.S., Earth Day has grown into a global tradition, which is now celebrated every year by more than a billion people in 180 nations around the world but many will do so with Facebook rather than megaphones.
