<P> Integrating recycling into K - 12 educational system has become a goal for many educators . Usually, it is integrated into science or social studies classrooms . This is due to its inclusion in the national education standards for both of these subject areas . Common areas that recycling is integrated into the curriculum include areas such as the study of natural resources, general environmental units, soil units, water units, community units, economic units, and geography units . Although interest is growing, major textbook publishers do not always include recycling in a textbook so teachers are left to supplement the textbooks with outside curriculum to meet the national standards . For example, in a unit about trees or natural resources teachers could include supplemental curriculum about recycling because in the textbook it is never explicitly covered . Non-profit organizations as well as governmental organizations have created supplemental curriculum for teachers to fill this void . Some purely non-profit groups include the Center for a New American Dream and Be SMART . Other creators of curriculum include governmental offices . Some of these include Oregon, California, and Waukesha County, Wisconsin . Also, some non-profit organizations have partnered with sections of the government to collaborate on educational materials . For example, the Keystone Center partnered with the United States Department of Energy and the National Energy Technology Laboratory to create curriculum on global warming . </P> <P> America Recycles Day (ARD) is the only nationally recognized day dedicated to encouraging Americans to recycle and buy recycled products . ARD is celebrated annually on November 15 . The World Recycling Day celebrated in most countries, though falls on July 8 . Thousands of events are held across the U.S. to raise awareness about the importance of recycling and to encourage American to sign personal pledges to recycle and buy products made from recycled materials . </P> <P> Started by the recycling sector organization National Recycling Coalition in 1997, America Recycles Day has been a program of national nonprofit Keep America Beautiful since 2009 . As the managing entity of America Recycles Day, Keep America Beautiful provides promotional and marketing support and resources to a network of local event organizers . It is sponsored by private and public entities and the EPA . </P> <P> Although America may not enjoy much of a reputation for environmentalism on the global stage, in some US cities, recycling levels are much higher than, for example, in the UK . </P>
