The day's theme this year is 'Science for Global Sustainability Interconnectedness, Collaboration, Transformation," the U.N. News Center reported.
"Science is our best asset for supporting inclusive and equitable development, and for building global sustainability at a time of uncertainty, and faced with biophysical limits of the planet," said United Nations Educational, Scientific and Cultural Organization's Director-General, Irina Bokova.
"We must also place science at the service of all, while observing the fundamental rights of the individual," Bokova said. "Above all, we must open a new chapter in scientific integration."
World Science Day for Peace and Development was established in 2001 with the purpose of renewing a global commitment to science as a tool to benefit society.
