    Hi there. Thank you for giving me accurate advice all the time.
    Please kindly check my speaking. Thank you so much.

    (my answer)
    In this lecture, professor explained two major causes of global warming.
    First reason is human activities. Because of human activities, such as driving a car, and using oil or natural gas, green house gas in the atmosphere is increasing dramatically.
    Second reason is deforestation. When we cut off the trees, the amount of carbon dioxide which trees can converge to oxygen is decreasing. Agriculture such as raising cattle and growing rice also can be a cause of global warming.
    The professor concludes that because of these causes, climate change, animals extinct, and storms frequently occur.

    The lecture illustrates 3 causes of global warming.
    first, human activities like using cars, electricity and heaters lead to increased green house gases . second, deforestation, cutting trees decreases the co2 conversion into o2.
    thirdly, agriculture like raising cattles and cultivating rice may lead to global warming . all resulting in climate changes , mass extinction and sever storms.

    The professor discusses the causes of global warming. She says that global warming happens when greenhouse gases, like carbon dioxide and other gases, are trap in the atmosphere; therefore, heat can’t escape to the space. She describes two main sources of greenhouse gasses. First, is due to human activities that use fossil fuels, like driving cars, heating the house with oil or natural gas, and using electricity from coal-fired power plants. Thereby, CO2 and other gases accumulate.
    The second cause of global warming is due to deforestation because fewer trees mean less carbon dioxide conversion to oxygen, so it accumulates in the atmosphere.
    And that is how the professor explains the causes of global warming.

    The lecture explained that from scientists’ research number of human activities are contributing to the global warming, by adding an excessive amount of green house gases such as carbon dioxide to the atmosphere. First of all, source of green house gases come from fossil fuel in industry, pollution from driving car, using electricity from cool-fired power plan, or heating our home with oil or natural gas. The second source is deforestation, because fewer trees mean less carbon dioxide conversion to oxygen.

    Global warming is primarily a problem of too much carbon dioxide (CO2) in the atmosphere—which acts as a blanket, trapping heat and warming the planet. As we burn fossil fuels like coal, oil and natural gas for energy or cut down and burn forests to create pastures and plantations, carbon accumulates and overloads our atmosphere.

    Global warming is the major cause of human extinction, in this lecture it said that global warming has two major reasons. First of all is that human acitivities such as driving cars, using electricity, or heating homes with natural oil will release carbon dioxide into the atmosphere and made a greenhouse effect. Second, the deforestation also contributing for greenhouse gases because over 150 years in the industrial age, many tress had been cut to make a space for factories. So the carbon dioxide can not turn into oxygen.

    The causes are many of which the main culprit is the increase in the greenhouse gases that is produced by burning fossil fuel and deforestation, thus intensifying the greenhouse effect leading to global warming. The four main contributors of the greenhouse effect are, water vapor, carbon dioxide, methane and ozone.

    Mining for coal and oil releases methane in the atmosphere. More ever the leakage from natural gas fields and landfills are additional source of methane. Excessive cutting down of the trees is another factor causing global warming. When deforestation happens the efficiency by which carbon dioxide is stored and oxygen released by the green plants are decreased to a huge rate in turn causing increased concentration of carbon dioxide that leads to increased greenhouse effect.

    The nitrous oxide from fertilizers, gases used for refrigeration and industrial processes are other factors that cannot be forgotten as the cause of Global Warming.

    The professor defines two causes of global warming.

    The first cause is human daily activities. The heat in the atmosphere raises gradually, as heat is trapped by CO2 emitted by human activities, for instance, driving a car, using coal-fired power plants, and using oil and natural gas.

    The second cause is deforestation. The more trees cut down, the less CO2 converted into O2. In instance, more heat is trapped in the atmosphere, leading to global warming.

    All of these causes generate climate changes, animals’ extinction, and storms.

    Scientists have determined that a number of human activities are contributing to global warming by adding excessive amounts of greenhouse gases, to the atmosphere.
    The first human also contributing to global warming because of driving cars, using electricity from coal-fired power plants, or heating our homes with oil or natural gas, we release carbon dioxide and other heat-trapping gases into the atmosphere.

    Deforestation also make the global warming become faster because fewer trees means less carbon dioxide conversion to oxygen. so the greenhouse gases become wider.
    As the concentration of greenhouse gases grows, more heat is trapped in the atmosphere and less escapes back into space. This is influence the length of seasons, and cause coastal flooding

    Generally, there are a lot of reasons that can make global warming. The use of excessive fossil fuels too much because of the vehicles are increasing is the main reason. Besides that, livestock and agriculture also have contribution such as using excessive methane gas as the fertilizers.

    The chemicals in fertilizers can not only damage the air lining, but also the waters, soils, and production of the food. Besides that, the reasons why global warming happen is because the factor of deforestation (land clearing) in big scale to make the public facilities, such as road, school, hospital, and another buildings.

As we burn fossil fuels like coal, oil and natural gas for energy or cut down and burn forests to create pastures and plantations, carbon accumulates and overloads our atmosphere.

    Greenhouse gases are released into the atmosphere in many ways, including through the burning of fossil fuels (such as coal and petroleum) and by deforestation. As some environments warm, they also release carbon that may have been stored for thousands of years.

    Animals, particularly sheep and cattle, produce large amounts of methane. Some fertilisers also release nitrous oxide, which is another greenhouse gas.

    Many industrial processes, such as cement production, liquid natural gas production and coal mining, produce or emit a variety of greenhouse gases.

    The major cause of global warming is the excessive amounts of
    greenhouse gases at the atmosphere. Greenhouse gases such as carbon dioxide accumulate in the atmosphere and trap heat that normally would exit into outer space.

    Global warming is caused by the destruction of human nature which resulted in a lot of things to fear humans. Examples such as the extinction of a species, and melting of polar ice. This global warming comes from human activities that use fuel fossil but it is also the effect of other human activities that produce carbon dioxide. And now ,this is our efforts to reduce and as far as we stop it by planting trees and caring for nature. As Example is to join the community that care about nature or we can minimize to use something that produce carbon.

    Our modern car culture and appetite for globally sourced goods is responsible for about 33% of emissions in the U.S. With our population growing at an alarming rate, the demand for more cars and consumer goods means that we are increasing the use of fossil fuels for transportation and manufacturing. Our consumption is outpacing our discoveries of ways to mitigate the effects, with no end in sight to our massive consumer culture.

      Global warming is the gradual heating of Earth’s surface, oceans and atmosphere.Most of the leading scientific organizations in the world acknowledge the existence of global warming as fact, according to a NASA report. Furthermore, 97 percent of climate scientists agree that the rate of global warming trends the planet is now experiencing is not a natural occurrence, but is primarily the result of human activity.Global warming begins with the greenhouse effect, which is caused by the interaction between Earth’s atmosphere and incoming radiation from the sun.Solar radiation passes through the atmosphere to the surface of Earth, where it is absorbed and then radiated upward as heat. Gases in Earth’s atmosphere absorb about 90 percent of this heat and radiate it back to the surface, which is warmed to a life-supporting average of 59 F (15 C). This very helpful process is called the greenhouse effect.

The two main causes of global warming are Human activities and Deforestation. Different forms of human activities like, using vehicle, excess use of fossil fuel, increase the amount of greenhouse gases in atmosphere . secondly, deforestation causes reduction in oxygen production and carbon dioxide observation. Other minor factor that causes global warming are growing crops, cattle grazing, unplanned establishment of industry.
    In conclusion, Global warming warming is very harmful for all the living creature. It can cause Flood, alter season change, effect in wildlife.
