GLOBAL WARMING Are we digging our own grave?: GLOBAL WARMING Are we digging our own grave? What is Global Warming ?: What is Global Warming ? Earth is naturally insulated by a delicate balance of heat-trapping (or "greenhouse") gases in the atmosphere. When the sun shines on the Earth, some of that heat is absorbed, keeping Earth warm enough to support life. What went wrong ???: What went wrong ??? The problem is that over the last century, we humans have been releasing more and more carbon dioxide and other heat-trapping gases into the atmosphere when we burn fuels and cut down forests. These additional gases have upset the natural balance of our atmosphere, trapping more heat than is healthy for the Earth . How have we hurt ourselves :: How have we hurt ourselves : Air : Polluted by industrial gas, aircraft fuel etc. Water : Polluted by industrial waste, plastics etc. Land : Polluted by non bio degradable products and chemicals. Signs Telling Us Everything is Not Normal ! : Signs Telling Us Everything is Not Normal ! Floods in the areas where the flood history is not common. Droughts in places, which were having good rainfall earlier. Atmosphere suddenly getting harsh in the terms of cyclones and thunderstorms. Life Forms Getting Affected:: Life Forms Getting Affected: The butterflies have migrated from warm southern zone to cooler northern zone. Due to melting of ice the life cycle of penguins is getting disturbed leading to their death. The coral growth along the Great Barrier Reef is getting reduced day by day. Polar Bears are facing extinction due the melting of polar ice. Looming Threats : : Looming Threats : Rising sea levels, leading to more coastal erosion, flooding during storms. Increased drought and increased incidence of wildfires Severe stress on many forests, wetlands, and other natural ecosystems Impacts on human health as mosquitoes and other disease-carrying insects and rodents spread diseases over larger geographical regions. Have we done anything to stop this?: Have we done anything to stop this? PowerPoint Presentation: Who can make a difference ?
