Green Technology, Why Go Green? Green Technology:


Green technology is the application of one or more of environmental science, green chemistry, environmental monitoring and electronic devices to monitor, model and conserve the natural environment and resources, and to curb the negative impacts of human involvement. The term is also used to describe sustainable energy generation technologies such as photovoltaics, wind turbines, bioreactors, etc. Sustainable development is the core of environmental technologies. The term green technology is also used to describe a class of electronic devices that can promote sustainable management of resources. The field of "green technology" encompasses a continuously evolving group of methods and materials, from techniques for generating energy to non-toxic cleaning products. The present expectation is that this field will bring innovation and changes in daily life of similar magnitude to the "information technology" explosion over the last two decades. In these early stages, it is impossible to predict what "green technology" may eventually encompass. The goals that inform developments in this rapidly growing field include: 1) Sustainability - meeting the needs of society in ways that can continue indefinitely into the future without damaging or depleting natural resources. In short, meeting present needs without compromising the ability of future generations to meet their own needs. 2) "Cradle to cradle" design - ending the "cradle to grave" cycle of manufactured products, by creating products that can be fully reclaimed or re-used. Source reduction - reducing waste and pollution by changing patterns of production and consumption. 3) Innovation - developing alternatives to technologies - whether fossil fuel or chemical intensive agriculture - that have been demonstrated to damage health and the environment. 4) Viability - creating a centre of economic activity around technologies and products that benefit the environment, speeding their implementation and creating new careers that truly protect the planet.

Examples of green technology subject areas


1) Energy Perhaps the most urgent issue for green technology, this includes the development of alternative fuels, new means of generating energy and energy efficiency. 2) Green building Green building encompasses everything from the choice of building materials to where a building is located. 3) Environmentally preferred purchasing This government innovation involves the search for products whose contents and methods of production have the smallest possible impact on the environment, and mandates that these be the preferred products for government purchasing. 4) Green chemistry The invention, design and application of chemical products and processes to reduce or to eliminate the use and generation of hazardous substances. 5) Green nanotechnology Nanotechnology involves the manipulation of materials at the scale of the nanometer, one billionth of a meter. Some scientists believe that mastery of this subject is forthcoming that will transform the way that everything in the world is manufactured. "Green nanotechnology" is the application of green chemistry and green engineering principles to this field.

Why Go Green?
1) It minimizes the degradation of the environment: Green Technology helps to minimize the environment degradation and thus helps to preserve it. 2) It has a zero or low green house gas (GHG) emission: Following Green Technology is advantageous in the sense that the green house gases emission is minimal and zero in some cases. 3) It is safe for use and promotes healthy and improved environment for all forms of life: Green technology is extremely safe for usage. It is easy to use and apply in our regular lives. The environment it promotes is healthy. 4) It conserves the use of energy and natural resources: As we all know, green technology promotes sustainable use of resources. Hence, it aims at minimal wastage of non-renewable resources like energy and fuel. 5) It promotes the use of renewable resources. 6) It helps to solve the problems of destruction of the environment and natural resources 7) It helps to increase health levels and the quality of life 8) It helps to conserve the ecosystem as well as costs to the government in overcoming the negative effects from development 9) It is an alternative to improving the national economy without harming the environment

10) Probably most well-known as "global warming", the science behind climate change is one of the most hotly debated topics among many people today. Although it is often a huge motivator behind the green movement, there are still those who fail to acknowledge its validity, many others who feel helpless and very few who ask the real question: Man-made or not, does it really matter? 11) The Economy: Choosing a sustainable lifestyle will obviously impact your choices as a consumer. For some of us, the positive impact of living simply and sustainable is increased by the impact on our local economy. For instance, buying from local farms means supporting neighbours whose success is directly related to your health and the health of the environment. 12) Climate Change: Probably most well-known as "global warming", the science behind climate change is one of the most hotly debated topics among many people today.

CONCLUSION
We live in a closed biosphere, we only have one planet and we need it to live. Despite what commercials say, going green isn't about buying the latest gadget or bamboo linens, it is about making choices that are sustainable. We need to reduce pollution, we are running out of clean drinkable water, our air is making us sicker and the amount of land where we can grow food is shrinking. We need to find new energy sources, oil or petroleum is highly polluting and will run out, and before it do we will fight wars for control of it if we are still dependant on it. We need to conserve resources for 2 reasons, we rely on many of them to survive, like trees, not only for shelter, but to create oxygen and the other is we are running out of places to bury the waste. We have new landfills being built every year and we are limited on where they can go. On the East coast where the population is denser many states have 2 options, burn it and contribute to more air pollution or ship it to another state and pay a lot more for waste removal. Another area to consider is our food, more of it is manufactured instead of grown, and all these empty calories are killing us. We have a huge increase in obesity and all the diseases that go with it. For the 1st time in history our children have a shorter life expectancy than we do. Not to mention the amount we waste and the worldwide impact of our eating habits, all the rain forest being clear cut to make way for our crops when we have the resources to grow the food here. I eat a local, organic diet to have a healthier more nutritious lifestyle, reduce the transportation effects of my food as well as support my local economy.
