                         How to Protect the Environment






                                                                                       20318 Lee, Yu-gyeong

            Changing environmental conditions have influenced the evolution of humans and other species
           since the appearance of life on earth. Indeed, until the Upper Paleolithic era, environmental
           crises arose almost entirely from natural conditions.
            However, since the emergence of large-scale hunting, and especially after the invention of
           agriculture, environmental crises have increasingly reflected the influence of human behavior
           and human policies. Anthropogenic effects on the natural environment have influenced ever-
           larger parts of the earth and have posed threats to social stability in regional contexts. Since the
           widespread use of fossil fuels in the industrial era, anthropogenic effects have extended their
           reach to literally global proportions.
            Consequently, a wide range of environmental problems has emerged; those problems include
           global warming, the hole in the ozone layer, acid rain, the destruction of tropical forests, the
           depletion and extinction of species, and the precipitous decline of biodiversity. Yet, while
                                                              all  of  these  problems  have  physical  and
                                                              environmental manifestations, their causes—
                                                              and their potential solutions—are invariably
                                                              bound up in human attitudes, beliefs, values,
                                                              needs, desires, expectations, and behaviors.

                                                               Unfortunately, humans have not been very

                                                              we all need to take proactive steps toward
