An Inconvenient TruthNot everyone can believe that humanity has come all this way to this point of advancement in our generation. We believed that the world was flat and was the center of the universe. We change the way we live, how we eat, how we communicate. We have evolved, we have created history, democracy, science. We landed on the Moon, we revolutionize industries, we fight inequality and we consume everything more than ever. To remind us, we are now 7 billion people living on this planet and the rate of growth appears to be limitless. We live and may not be aware of what is happening in the big picture, that our technological progress could affect something in the world. We spread everywhere, we reproduce everything like mass production, like a virus. “An Inconvenient Truth” is an Academy Award-winning documentary focusing on global warming and CO2 emissions over the past decade. It tells a story of how our progress affects mother earth in a very big picture. We may not notice it, but the truth is that even though we are small, we could still become harmful in so many ways. To be more precise, it is about reminding us that our worst enemy is ourselves. In the movies, Al Gore shows us a lot of uncomfortable information. The most terrifying one concerns the rapid increase in CO2 emissions in recent decades. It was mostly about mass consumption without any environmental awareness. We already knew that the concentration of CO2 is the main cause of global warming, because the emission rate is perfectly correlated with the increase in temperature. The higher the CO2 concentration, the greater the temperature increase. If we don't do something, the crisis will accelerate. This has led to many catastrophic events in the past in… middle of paper… resource: The document states that natural resources are also the part of concern . Depletion could increase the current price of all natural resources. So renewable resources have also become a subject of concern for providing essential ecosystem services that are not captured by the market price. Conclusion At the end of the presentation, he shows us a vague image with a pale blue dot on the left. He said this is the photo taken by the Voyager 1 space probe in 1990 and that little pale blue dot that is evidently our earth. Then he quotes Carl Sagan, which I think says it all. "That's home, that's us - every saint and sinner in the history of our species has lived there; on a speck of dust, hanging on a ray of sunshine. In our darkness, in all this vastness, there is no clue that the Help will come from elsewhere to save us from ourselves."
