pens when greenhouse gases (carbon dioxide‚ water vapor‚ nitrous oxide‚ and methane) trap heat and light from the sun in the earth’s atmosphere‚ which increases the temperature. This hurts many people‚ animals‚ and plants. The greenhouse effect is when the temperature rises because the sun’s heat and light is trapped in the earth’s atmosphere. This is like when heat is trapped in a car. On a very hot day‚ the car gets hotter when it is out in the parking lot. This is because the

Greenhouse Effect When one starts a car or burns wood‚ the last thought on their mind is the consequences to these actions. Unfortunately‚ the daily dangers to earth are not widely know. Due to the constant change of society‚ this planet must cope with various problems. One of the most important ecological structures is the ozone layer. The same shield that protects us from the sun ’s deadly radiation‚ can also act as a blanket engulfing us in heat. This situation is know as the greenhouse effect

also wonder why disastrous weather events like super-storm Sandy continue to increase in their frequency and severity? Many modern scientists attribute these dangerous environmental trends of global warming to the ‘greenhouse effect’. The ‘greenhouse effect’ results from greenhouse gases such as carbon dioxide rising into the atmosphere‚ trapping infrared radiation from the sun‚ and emitting ultraviolet radiation that can puncture the earth’s stratospheric ozone layer. A healthy ozone layer should

produce more and more cars. Factories and cars are one of the biggest air pollutants. To begin with‚ drivers should use unleaded petrol. However‚ they use leaded petrol‚ as it is cheaper. The cars should be banned from city centres‚ as they cause big smog. Another serious problem is that there are no filters in factories. Moreover‚ factory managers save their money. They do not care about nature and what may happen with it. Some plants just cannot afford to buy filters‚ as they are too expensive

The Greenhouse Effect The greenhouse effect‚ in environmental science‚ is a popular term for the effect that certain variable constituents of the Earth’s lower atmosphere have on surface temperatures. These gases--water vapor (H2O)‚ carbon dioxide (CO2)‚ and methane (CH4)--keep ground temperatures at a global average of about 15 degrees C (60 degrees F). Without them the average would be below the freezing point of H20. The gases have this effect because as incoming solar radiation strikes

Greenhouse gases Carbon dioxide is a colourless‚ odourless gas that makes up .04 percent of the earth’s atmosphere. It’s released by the breakdown of organic materials‚ by animals when they respire‚ and by the burning of fossil fuels. Carbon dioxide isn’t toxic—after all‚ we exhale it with every breath and use it to make our drinks fizzy. However‚ carbon dioxide is considered a pollutant because‚ as a greenhouse (heat-trapping) gas‚ it’s a significant contributor to global warming. In the last 150

Case 1.2 Green Economics Taking account of environmental costs People have become concerned by a number of environmental problems in recent years. These include: The greenhouse effect. This is caused by carbon dioxide and other gases emitted again by power stations‚ various industries and cars. The fear is that these gases will cause a heating of the Earth’s atmosphere. This will lead to climatic changes which will affect food production. It will also lead to a raising of sea levels and flooding

æ Solutions Reducing use of fossil fuels would significantly reduce the amount of carbon dioxide produced‚ as well as reducing the levels of the pollutants which cause acid rain (Solutions). This can be achieved by either using less energy in general‚ or using alternative energy sources. There are many ways to conserve energy such as: turning off any lights in a room which isn¡¦t being occupied. If you¡¦re making a short trip to the store and it is in walking distance conserve energy and take
