NEW YORK, April 22 (UPI) -- United Nations Secretary-General Ban Ki-moon recognized Earth Day on Tuesday by calling on "people everywhere to raise their voices" as the international community responds to climate change.
"As our population grows we have to recognize that our consumption of the planet’s resources is unsustainable. We need a global transformation of attitude and practice. It is especially urgent to address how we generate the energy that drives our progress. Burning fossil fuels is the principal cause of climate change, which increasingly threatens prosperity and stability in all regions. That is why world leaders have pledged to reach a global legal climate agreement in 2015."
In an effort to work toward making that new climate treaty a reality, the secretary-general said Tuesday that he will be extending invitations to heads of state as well as private sector and civil society leaders to attend a Climate Summit where all can "showcase initiatives and forge alliances that can help launch a sustainable future."
The Climate Summit is scheduled for September 23 in New York.
