Lyrica cheap price When sunlight heats the earth’s surface, while some heat radiates back into the atmosphere, some of the heat is absorbed by gases in the atmosphere, keeping the earth warm. This is the greenhouse effect, and some of these greenhouse gases are Carbon dioxide, water vapor, methane, Ozone, nitrous oxides, and chlorofluorocarbons. Deforestation, use of fossil fuels, fertilizers and certain industrial processes that release fluorinated gases increase the levels of greenhouse gases leading to global warming that manifests itself as raging storms, deadly heat, continuous rain, record floods and so on. The main goal of green technology is to conserve nature, to protect our environment and to remedy the negative impact that technology advancements have on it. Some of the examples of green technology are: Green chemistry that involves the design of chemicals, chemical processes and commercial products which avoids the creation of toxic substances by creating alternatives to hazardous chemicals while reducing wastes; Green Nanotechnology that aims in producing nanomaterials and products without harming the environment and life in our planet; Green energy that involves producing energy through natural resources like sun, wind, rain, tides, plants, algae etc., for example, generating electricity from solar, wind, geothermal, biomass, and low-impact hydro facilities and Green Building that refers to a structure that is built using an environmentally friendly process from design, maintenance to renovation.
