Respected dignitaries on and off the stage, teachers and my dear friends
Today I am going to talk about one of the greatest problem humanity is facing right now, which Global is warming.
Global warming is a phenomena in which there is a gradual increase in the average temperature of the Earth's atmosphere and its oceans. This change is believed to have serious implications on our planet and is permanently changing the Earth's climate. This can be also seen as an implication of man’s greedy nature and the over exploitation of our mother nature in the hunt for more and more resources. For centuries we brutally exploited our resources, thoughtlessly wasted it and reaped profits without a thought about our future generations. Over the last century, global average temperature has increased by more than 1°F or 0.7°C .Global warming is primarily a problem because of too much carbon dioxide in the atmosphere which acts as a blanket, trapping heat and warming the planet more and more. As we burn fossil fuels like coal, petrol, diesel and natural gas for energy or cut down and burn forests to create plantations, carbon accumulates and overloads our atmosphere. Certain waste management and agricultural practices aggravate the problem by releasing other potent global warming gases, such as methane and nitrous oxide. A warming world also has the potential to change rainfall patterns, increase droughts and severe storms, melt glaciers, increase sea levels, and even change plant and animal behavior. Today we have substantial scientific evidence which indicates that an increase in the global average temperature of more than 2°F above from where we are today poses severe risks to natural systems and human health and well-being. The world has already realized the potential aftermath of Global warming and have started massive campaign to reduce its effect. There is no single solution to global warming. But a multi faced approach like focusing more towards clean and green energy production, increasing the efficiency of the current systems, gradual facing out of the fossil fuels, prevention of deforestation and ensuring sustainable development etc. are some of the ways ahead. Countries around the world have been submitting their pledges to the United Nations, setting out how far they intend to reduce their greenhouse gas emissions over a period of time.
As students, we also can play a major role in compacting global warming. Despite of the great threat it possesses, our society is still not aware of it. The war against global warming will be effective if and only if a common man realizes that he is also contributing to it when he even forget to switch off electricity after the usage. As the future scientists and decision makers, lets take a pledge towards focusing and developing more sustainable technologies .We can also conduct campaigns to increase the awareness and the need to respect our mother nature. Its interesting to note that even a reduction in meat consumption by humans can help in compacting global warming. .Our resources are precious and it belongs to all, primarily for our survival and not for luxuries.The world can survive without mankind but mankind cannot survive without this world.
