Global warming and greenhouse effect
Global warming is when the temperature rises or when the earth heats up abnormally as a greenhouse effect. It happens when gases like carbon dioxide, methane, nitrous oxide and water vapor trap heat and light from the sun in the earth’s atmosphere. This is dangerous to the living things on earth…and can even cause death. Global warming can cause the numerous ice and snow to melt, adding water to earth, causing numerous islands to sink.
Global warming and green house effect are two highly-related topics. A greenhouse is a small glass house used to grow plants especially during cold climates like winter. It works by trapping heat from the sun and does not let it out, which causes the house to heat up to keep the plants inside alive. Global warming is when the earth is too warm. Greenhouse is like a car parked in the sunlight. It can let the heat get in, but traps it inside.
Greenhouse gases in the earth’s atmosphere act like the glass panes in a greenhouse. When sunlight enters the atmosphere of the earth, it passes through the blanket of greenhouse gasses. Air, water, and land absorb the sunlight’s energy when it reaches the earth. Once absorbed, some energy passed back into space, out of the earth, but because of so many greenhouse gases, they remain trapped in the atmosphere by the greenhouse gases, causing much heat for the world.
Before the problem of global warming, greenhouse effect normally is good for the biosphere. Without it, the earth would be freezing during nighttime, when the sun is absent; or it can be burning hot during daytime. But if there will be too many gases, the earth gets unusually warmer, causing death to plants, animals and to the people on it.
What cause global warming and what we can do
Electrical pollution is one of the causes of pollution. Fossil fuels like petroleum and oil, the source of electricity, contribute to greenhouse gasses. They are made of dead animals and plants. When fossil fuels are burned, many pollutants are sent to the air, some of which are greenhouse gasses. Contributing to global warming and greenhouse effect are other very common things that use energy and pollute the air are turning on a light, watching T.V., listening to a stereo, using a hair dryer, riding a car, using the microwave or air-conditioner and many others that we just do every single minute on earth.
Another thing that causes global warming is when people cut down trees, disabling the trees to collect other greenhouse gasses like carbon dioxide and producing oxygen. Without oxygen, humans cannot live.
People can contribute to the prevention of global warming by carpooling, recycling garbage, planting trees and not using things containing chemicals that produce more greenhouse gasses. It shall be difficult if the Earth, our habitat, is destroyed. It will fire back to us. Global warming and green house effect prevention is a collective effort. All people must cooperate with each other to help save the planet, not only for our generation but for the next generations as well.
