Environmental conservation is one of the most pressing of the global issues humankind faces. Global warming, acid rain, ozone depletion, tropical rainforest destruction, and river and ocean pollution are just some of the results of human activities that are having adverse affects on the Earth. In 1992, the year of the Earth Summit, the Asahi Glass Foundation established the Blue Planet Prize, an award presented to individuals or organizations worldwide in recognition of major contributions to solving global environmental problems. The Prize is offered in the hopes of encouraging efforts to bring about the healing of the Earth’s fragile environment. The award’s name was inspired by the remark "the Earth was blue," uttered by the first human in space, Russian cosmonaut Yuri Gagarin, upon viewing our planet. The Blue Planet Prize was so named in the hopes that our blue planet will be a shared asset capable of sustaining human life far into the future.
