 a lot of people need food but there are not enough farmers so a lot of people are starving to death ☹️❌🍝🍟]]> 2017-10-03 14:38:26 UTC https://padlet.com/meilingcheng/unit3_6B/wish/193456652 meilingcheng https://padlet.com/meilingcheng/unit3_6B/wish/828066787 2020-10-14 09:44:41 UTC https://padlet.com/meilingcheng/unit3_6B/wish/828066787 meilingcheng https://padlet.com/meilingcheng/unit3_6B/wish/828072642 2020-10-14 09:48:20 UTC https://padlet.com/meilingcheng/unit3_6B/wish/828072642 https://padlet.com/meilingcheng/unit3_6B/wish/840372603 One problem that was brought about by human action and is definitely affecting the hydrosphere globally... The greenhouse effect is caused by the atmospheric accumulation of gases such as carbon dioxide and methane, which contain some of the heat emitted from Earth's surface.CO2, Methane and Nitrous Oxide are greenhouse gases, they trap the heat]]> 2020-10-19 09:29:51 UTC https://padlet.com/meilingcheng/unit3_6B/wish/840372603 https://padlet.com/meilingcheng/unit3_6B/wish/840417057 The article let me think about the greenhouse effect is a very serious and important problem that we need to face it. The atmosphere and the environment has been contaminated. This business society has increased the air pollution so we need to reuse to let the factory stop working to decrease the emissions of the CO2. ]]> 2020-10-19 09:53:49 UTC https://padlet.com/meilingcheng/unit3_6B/wish/840417057 https://padlet.com/meilingcheng/unit3_6B/wish/840461559 In our world, there are so many problems that we need to confront it, For example the greenhouse effect. This problem give people a lot of annoyance. If we continue to do that, the Earth will disappear. We need to do somethings that it good for the Earth such as use less air conditioner. When we are breathing, the trees suck the CO2.

We save the Earth so that we need to below:
1.Reduce the air conditioner.
2.Adjustment the air conditioner below 25c.
3.Reduce plastic bag instead Eco bag.
4.Recycle the plastic, paper and aluminium can.]]> 2020-10-19 10:34:03 UTC https://padlet.com/meilingcheng/unit3_6B/wish/840483592 https://padlet.com/meilingcheng/unit3_6B/wish/840483608 Greenhouse Effect is a process that occurs when gases in Earth’s much warmer than it would be without an  atmosphere.
If we want to save Earth, we can do that. 
-Reduces to use the styrofoam’s

The four main greenhouse gases are :

1. Carbon Dioxide
2. Methane
3. Nitrous Oxide
4. Fluorinated Gases

If we to save our Earth , we can :

---Shop wisely , buy less food with plastic and bring our own reusable shopping bags .

---Plant trees more often , because trees provide food and oxygen . They help save energy , clean the air and help combat climate change . 

---Conserve water , the less water we use , the less runoff and wastewater will end up in our ocean]]> 2020-10-19 11:41:51 UTC https://padlet.com/meilingcheng/unit3_6B/wish/840596228 https://padlet.com/meilingcheng/unit3_6B/wish/840634252 Matthew

Latitude of water resources in water can be reduced. Mountain snow melt, reduce the use of water in high altitude. Polarization of the low-latitude rainfall, increased desertification, increase rainfall rainforest, in the high-latitude regions in seasonal floods. Hundreds of billions of people will be a serious water shortage in the inland areas started desertification. Euro-Mediterranean region began desertification, more than 3 billion people suffering from floods or drought.

Increased coral bleaching on the ecology, species distribution change, forest fires increase. The vast majority of coral bleaching, alpine and polar serious ecological imbalance, and about 30% of biological extinction. Coral large extinction, polar species extinction, a major change in the ecological system. Ecological carbon absorption by 40%, increase the greenhouse effect, the marine ecological change. More than 40% above the extinction of species.

Climate heat waves, hurricanes, snowstorms increase. A regional climate anomalies. Ocean circulation weakened, mid-latitude started cold, low-latitude warming intensified. Abnormal global climate. Most regions of devastating climate.

Greenhouse gases are crucial to keeping our planet at a habitable temperature.Without the natural greenhouse effect,the heat emitted by the Earth would simply pass outwards from the Earth's surface into space.The Earth would have an average temperature of about -20°C.
To diminish greenhouse effect,we have to learn "Reduce reuse and recycle energy".For example I do not switch on air conditioner during sleeping time at night to save electricity.]]> 2020-10-19 12:42:05 UTC https://padlet.com/meilingcheng/unit3_6B/wish/840751756 lailaiwong229 https://padlet.com/meilingcheng/unit3_6B/wish/840810868        The greenhouse effect is caused by the atmospheric accumulation of gases such as methane ,CO2 and nitrous oxide.

According to statistics, because acid rain can travel long distances with air currents, beyond The restrictions of national boundaries have led to the prevention of acid rain not only through the efforts of a single country, but also by the collective prevention of multiple countries. However, due to factors such as economic development and political conditions among countries, the acid rain is being promoted. Suddenly, the strength of the work is weak, and due to the decrease in the use of fossil fuels, the scope of acid rain is still increasing.

It makes the Earth much warmer than it would be without an atmosphere . The greenhouse is a building with the glass walls and  glass roof. Greenhouse traps the Sun's heat . The greenhouse effect works much the same way on Earth . Gases in the atmosphere, such as carbon dioxide , trap heat just like the glass roof of a greenhouse . Human activities are changing Earth's natural greenhouse effect .

If you want to ask me, I think.... First of all, let me talk about:

Reason──

1. Things made by humans, such as steam and locomotives, power plants, etc., are all causes of global warming. Exhaust gas emitted by steam and locomotives is also hot gas. When combined with air, CO2 ( Carbon dioxide), carbon dioxide has the effect of endothermic, and these gases not only absorb heat, but also hot gas, so they will float into the atmosphere, cannot leak from the atmosphere, and block in the atmosphere. Therefore, ultraviolet rays can come in and out, and heat makes the world The temperature rises.

2. "Thermal power generation" is the most widely used method of power generation. It must consume and burn coal... and other materials. The process of consumption will emit carbon dioxide, so... (The rest is the same as above).

Result──

The earth caused by global warming has several almost irreversible natural environmental problems:

1. Sea level rise.

2. The surface temperature (sea surface temperature) rises.

3. Coral bleaching (cooked~).

4. There are floods, droughts, heat waves, hurricanes and tornadoes around the world.

5. Animals living on the two poles of the earth (such as polar bears, seals, penguins... etc.) have their homes reduced due to the melting of icebergs, and even polar bears have died from heat and drowning.

In fact, there are still many results, human beings cause environmental pollution, the spirit of all evil!]]> 2020-10-19 14:26:43 UTC https://padlet.com/meilingcheng/unit3_6B/wish/841205681 https://padlet.com/meilingcheng/unit3_6B/wish/841362194 The greenhouse effect is mainly caused by the excessive burning of coal, oil, natural gas and other fossil fuels in modern industrial society, which releases a large amount of carbon dioxide gas after burning.  Carbon dioxide gas has the functions of heat absorption and heat insulation. It increases in the atmosphere, just like forming an invisible glass cover, so that the heat radiated by the sun to the earth cannot be dissipated to outer space, thus causing the earth's surface to gradually heat up.  Therefore, carbon dioxide is also called a greenhouse gas.]]> 2020-10-19 15:00:46 UTC https://padlet.com/meilingcheng/unit3_6B/wish/841362194 https://padlet.com/meilingcheng/unit3_6B/wish/844408208 The greenhouse is made of glass walls and glass roof.The greenhouse is always warm inside, although it is winter.The greenhouse is used for growing plant, like tomato and flowers.The greenhouse effect is one of the thing that makes Earth a comfortable place to live.Global warming is very serious now, so we should try to turn off unnecessary power and turn off the air-conditioning.Do you want to help, then you do what I say.]]> 2020-10-20 11:55:40 UTC https://padlet.com/meilingcheng/unit3_6B/wish/844408208 https://padlet.com/meilingcheng/unit3_6B/wish/844814612 Greenhouse effect is the situation of gases in  Earth's atmosphere trap heat from the sun and keep the earth warm, those gases are called greenhouse gases, carbon dioxide is one of the examples.When the amount of carbon dioxide or other greenhouse gases are increased, they enhances the greenhouse effect by trapping more heat in the atmosphere and the average temperature of the Earth rises.This is also known as global warming.
Many human activities such as cutting down trees, burning fossil fuels in power stations also produce greenhouse gases , leading to global warming.]]> 2020-10-20 13:48:11 UTC https://padlet.com/meilingcheng/unit3_6B/wish/844814612 meilingcheng https://padlet.com/meilingcheng/unit3_6B/wish/847173940 2020-10-21 01:46:45 UTC https://padlet.com/meilingcheng/unit3_6B/wish/847173940
