This is a documentary worth pondering for all human beings after watching it, because the life of the earth is in the hands of every human being! In the documentary, former U.S. Vice President Al Gore, as an environmental ambassador and his team of scientists, formed a powerful analysis through the scientific data measured and calculated over the years, and visited many countries and places to give speeches and popularize science. response.
Gore as a good politician: clear-headed, quick-witted, and lively in his speech. Why not stay in politics and start environmental protection? This is related to his son who was seriously ill and was hospitalized. God was generous to him and his son was discharged from the hospital. After staying in the hospital for nearly a month, Gore seriously thought about a lot of questions, and also figured out a lot of questions, what is meaningful Work? What kind of life is satisfying? How long can the earth survive? Yes, the talent on earth is important, and it is the most important for his family!
With the continuous demand of human beings, the booming of heavy industry: the popularization of automobiles, air conditioners, high-rise buildings, the earth has been seriously polluted and the atmosphere has become thicker and thicker, so that the heat from the sun cannot be reflected and is reflected back. Earth: It is no wonder that the summer sun has been particularly dazzling in recent years. I remember that the color of the sun was golden yellow when I was a child, but now the sun looks white and makes it impossible to open my eyes.
For example: In the past, the atmosphere was normally very thin, and when the sun hit the earth, it would be reflected into outer space, so the sunlight seen by the naked eye was weak and yellow, like a soft ordinary light bulb, but now the atmosphere is abnormally thick, and the sun shines on the earth. It can't be reflected from outer space and return to the earth, so that the sunlight seen with the naked eye is very strong and white like a dazzling energy-saving light bulb, so it is recommended to wear sunscreen all year round now, regardless of men, women and children, just use SPF in summer Higher will be useful.
So what exactly makes the atmosphere thicker? It's carbon dioxide emissions! Some data show that cars and heating only account for 54% of carbon dioxide emissions, and the remaining 46% comes from people's daily consumption. In fact, all human activities and food consumption produce harmful carbon dioxide. The following is the amount of carbon dioxide emissions in daily life:
A large-displacement car travels 20,000 kilometers in a city every year, and it emits 2 tons of carbon dioxide. The engine releases 2.5 kilograms of carbon dioxide into the atmosphere for every liter of fuel it burns, so people are urged to take the bus without buying a car, with only one or two stops to cycle or walk for exercise.
The human body releases about 1 kg of carbon dioxide through breathing every day.
Plants absorb CO2 during the day and release it at night, so the net CO2 emissions from plants are zero. A medium-sized plant can absorb about 6 kilograms of carbon dioxide every year, so we should call on the government to plant more trees and afforestation, and insist on doing a good job in the greening of the community. In the end, everyone suffers. After all, planting greenery at home is limited.
Computer use indirectly emits an average of 10.5 kg of carbon dioxide a year, so in addition to work, please refrain from surfing the Internet, chatting, and playing games.
The indirect carbon dioxide emission of halogen bulbs is 10.8 kg per year: please save electricity, and try not to do things that can be done in daylight during the day, so as to save electricity and reduce emissions and protect your eyes.
The indirect carbon dioxide emission of washing machines is 7.75 kg per year: try to do manual washing if you can: such as underwear and small items. Eggs are a natural food, but in order for them to be put on the table, they need to be raised, packaged and transported.
Chicken farms also need maintenance. The greenhouse gas emissions from chicken production are 4 times that of beef production. Thinking that I have been eating less and less chicken for many years, I am afraid that it is very bad for the body, especially fried chicken.
Compared to frozen food, although the process of producing grain, vegetables and fruit emits less carbon dioxide than meat, frozen food needs to go through the process of cleaning, heating, packaging and freezing, which all contribute to carbon dioxide emissions. I never buy frozen processed foods, such as wontons and dumplings, which are freshly bought and packaged, and they taste better.
Therefore, people must strictly control the energy consumption in daily life, so as to effectively avoid the emission of carbon dioxide and prevent the release of tons of harmful gases into the atmosphere. If we keep the air conditioner temperature between 24 and 26 degrees Celsius, not only can we save 5% to 10% in electricity bills, but we can reduce the carbon dioxide gas emitted by each household by 300 kilograms per year.
The actual problem now is that global warming has threatened the normal life of polar bears. For this reason, I watched the documentary "Go to the North Pole" in 2012. It showed that the icebergs in the Arctic began to melt after the climate warmed. The splendid scenery of the icebergs from the top has turned into a continuous ocean. The cute little polar bears follow the mother bear to wander around, and sometimes dive into the water to swim. Although they are born to swim, they have thick fur. It is the most suitable for surviving in icebergs. No wonder there have been reports of polar bears drowning in water a few years ago: could it be that it fell asleep?
In "The Inconvenient Truth" filmed in 2006, it also detailed that the melting of the icebergs in the Arctic and Antarctic will cause the sea level to rise, and it will pour water into low-lying cities, so the lethality is unimaginable! Of course, if human beings can take care of themselves: pay attention to emission reduction and environmental protection, I believe it will definitely improve. As for how long the earth can survive? This is closely related to everyone on earth!
