Sometimes I can’t help asking myself, what’s the matter with our plant? Distinct seasons has gone forever, the summer temperature refresh the annual historical limit, 2012 is the hottest year of United States of America since meteorological records in 1895, the annual average temperature is 12.94 ℃, breaking the record in 1998. The polar ice and snow ice accelerate to melt at the speed of 8% for every year, obviously we suffer global temperature warming, It's predicted if the earth's surface temperature develop at the present rate, temperatures will rise 4 Celsius by 2050 global, North and south polar ice will melt significantly, leading to a significant rise in sea level, a number of island countries and coastal city will be submerged in the water, including several famous international city: New York, Shanghai, Tokyo and Sydney

The exacerbate greenhouse effect has obvious influence to our daily life, in order to alleviate this phenomenon to strengthen our environmental aware, the annual Earth Hour Day and Earth Day is to promote people to save energy, protect the earth. The annual electricity consumes large amounts of earth energy,while lighting consumes accounts for nearly 25% electric energy, low carbon environmental voice is louder and louder. Nowadays, a high efficiency and energy saving LED lamp is gradually replacing traditional lighting into the horizon, according to the "New York Times" (The New York Times) report, if all of the use of LED lighting technology replace traditional lighting lamp, only save power consumption, can reduce 50% of carbon dioxide emissions in the world in a short period of 20 years.

    A light-emitting diode (LED) is a semiconductor light source. LEDs are used as indicator lamps in many devices and are increasingly used for general lighting. Appearing as practical electronic components in 1962, early LEDs emitted low-intensity red light, but modern versions are available across the visible, ultraviolet, and infrared wavelengths, with very high brightness.When a light-emitting diode is switched on, electrons are able to recombine with holes within the device, releasing energy in the form of photons. This effect is called electroluminescence, and the color of the light (corresponding to the energy of the photon) is determined by the energy band gap of the semiconductor. An LED is often small in area (less than 1 mm2), and integrated optical components may be used to shape its radiation pattern. LEDs have many advantages over incandescent light sources including lower energy consumption, longer lifetime, improved physical robustness, smaller size, and faster switching. However, LEDs powerful enough for room lighting are relatively expensive, and require more precise current and heat management than compact fluorescent lamp sources of comparable output.Light-emitting diodes are used in applications as diverse as aviation lighting automotive lighting, advertising, general lighting, and traffic signals. LEDs have allowed new text, video displays, and sensors to be developed, while their high switching rates are also useful in advanced communications technology. Infrared LEDs are also used in the remote control units of many commercial products including televisions, DVD players and other domestic appliances. LEDs are also used in seven-segment display.…

    However, this does not hold true anymore; as of 2009, DST “results in an overall increase in residential electricity demand”, with an overall increase of 1% mostly centered around the time surrounding the change between daylight savings and standard time. (Source F). This affirms that DST has caused a dangerous increase in energy consumption, most likely because of the decreased amounts of daylight and therefore the decreased amounts of time people can spend outside of their homes. Since so many individuals are forced to stay indoors, they resort to using different types of electricity for entertainment, thereby increasing energy consumption per person, and also for the world as a whole. The implementation of daylight savings has aided in the fostering of a pressing global issue that could eventually cause massive unforeseen consequences for the entirety of humankind, which is why such a social construct should be expelled from…

    When the system was first adopted, the United States claimed that daylight savings was a way to save energy, reducing the amount of energy consumed by the public as they had less time to use energy during daylight or evening time (Source C). Although the United States Department of Transportation (DOT) stated that “the total electricity savings associated with daylight savings time amounted to about 1 percent in spring and fall” (Source C). The records from the National Bureau of Economic Research states differently as it said that no real energy-saving has been recorded from daylight savings in a study as of 2008. The study found that “daylight savings time resulted in an overall increase in residential electricity demands” (Source F). With people staying home due to having less daylight electricity is in more demand for household use. In societies today, electricity use explodes in demand due to the lack of daylight available outside. With daylight savings in use, the majority of Americans today stays home and consumes more electricity than…

    Conservation of energy is wonderfully demonstrated through the employment of daylight saving time. Energy consumption is lessened which greatly impacts the preservation of the environment. This is evidenced by Source B, which states that electricity usage is reduced by about one percent during each day. By DST, if less energy is being consumed, the opportunities of mankind having a safer and more presentable environment are much higher. Furthermore, DST not only aids the surroundings but also teaches people to use energy wisely. Individuals will be fully aware of the benefits that come with saving energy. Continuous application of DST provides a well preserved atmosphere.…

    Because of the climate change, the earth is in danger. People don’t realize that the things they use or do every day are hurting the earth and living things. Nature.org says, “…one-fourth of Earth’s species will be headed for extinction by 2050 if the warming trend continues at its current rate…” Because the temperature is increasing, ice is melting. Because ice is melting, sea levels are rising. Higher temperatures don’t only melt ice but evaporates the moisture in the air. Evaporation will take away all of the land’s water leaving it as dry as a desert. With a drought now in progress, it will make it harder to find water and support agriculture.…

    “The amount of light in the sky increases an average of about 6% every year”. The author uses statistics on the increase of artificial light to represent the amount of money that is wasted annually. “Much of this light is wasted energy, which means wasted dollars”. This particular sentence demonstrates that too much light is too much waste. In fact the light pollution has become a problem that cities and towns are making changes.. “North America and Europe are changing to LEF streetlights, which offer dramatic possibility for controlling wasted lights.”…

    Nonetheless, saving energy not only benefits the planet, but our ‘pockets’ as well. According to the U.S. Department of Energy, a simple task like replacing the light bulbs in your home can save up “75% energy of the 10% home energy costs.” Or simply unplugging electronics and appliances when not in use – a task made easier by using multiple-outlet strips, which can turn everything off with the flip of a switch – can save you money. For example, Leaving a computer on all day can cost about “21 cents per day, or about $75 per year” (U.S. Department of energy). Also, according to Goldemberg’s article “Energy for the New Millennium”, 78% of CO2 and 23% of methane is expelled from energy activities which are ultimately major contributors to indoor air pollution, urban air pollution, acidification and global…

    We have inherited much from planet Earth, such as natural resources and every single one of the living creatures that planet earth is home to. However, in the preceding decades much has happened to our environments. After years of burning unlimited amount of fossil fuels and releasing harmful gases into the atmosphere, we have reached a point where it has affected our ecosystem. As result of the changes in our ecosystem, we have placed extreme amount of stress on living organisms. Animal population decreasing is one aspect of life; we have witnessed certain animal population decrease to dangerous levels but not anywhere close to the extinction rates of today. As selfish as humans might be, now is the time for us to take responsibility for our actions and start caring about our soon to be extinct wild life.…
