Humanity's Greatest Challenge

                         Climate change is humanity's greatest challenge. Climate change is one caused by us, humans. We are destroying our nature. Climate change is caused by Global warming, the abnormal heating of the earth for too much heat is received by the earth from the sun due to the depletion of the ozone layer.
                         Do you notice? In the summer, rain falls and during the 'ber months, we experience too much heat. That is one cause of global warming. We must help each other in preserving our environment for the future. According  to Henry Miller, "The world is not to be put in order, The world is in order. It is for us to put ourselves in unison with this order."
                        Climate change is humanity's greatest challenge and we must act together or else face the consequences. :)
