Growth of the Internet essays

Growth of the Internet essays Growth of the Internet in the Past Ten Years The Internet is a network of networks that allows different computers of all types to communicate with each other. It is becoming more commonly used throughout the world. Since the Internet has become more valuable over the years for people and companies to communicate, it has shown significant development in the past ten years. Starting in the early 90s there were many advances made and the number of the hosts broke 1,000,000. The NSF later lifted the restrictions on commercial use paving the way for Internet commerce. This advancement lead to the first order of a mushroom, pepperoni with extra cheese pizza over the net. Six years later, for 40 million people become connected to the Internet and spend over one billion dollars on Internet shopping malls. By this time, there were over 150 countries connected to the Internet, with the number of computer hosts coming close to ten million. The expansion to almost ten times its size in only six years is tremendous. The Internet is now almost as common as a microwave in the household. By then end of 2002, the number of hosts had grown to over 162 million. This was a growth of over 112,000,000 in the short time of six years. During those six years, many laws were added to help prevent kids from looking at inappropriate sites and to help make shopping (releasing credit card numbers, security, etc.) safer over the Internet. With the Internet growing as fast as it is and more people using it as a way of life, there are going to be many more security issues that need to be addressed. People are learning how to use the Internet to accomplish their every day tasks and eventually business related social interactions, such as department store shopping or grocery shopping, will become fewer and far between. ...

Green Technology Definition and Examples

Green Technology Definition and Examples Green technology, also known as sustainable technology, takes into account the long- and short-term impact something has on the environment. Green products are by definition, environmentally friendly. Energy efficiency, recycling, health and safety concerns, renewable resources, and more all go into the making of a green product or technology. Go Green or Face Extinction? Since the invention of the steam engine kicked off the Industrial Revolution, our planet has suffered rapid changes in climate that include increasingly severe droughts, increased depletion of groundwater reserves, seawater acidification, rising seawater levels, the rapid spread of diseases and macroparasites, and the extinction of species.  Unless we intervene, these changes may prove irreversible. Green technology offers us the best hope to counteract the effects of climate change and pollution. Why? The world has a fixed amount of natural resources, some of which have already been depleted or ruined. For example, household batteries and electronics often contain dangerous chemicals that pollute soil and groundwater with chemicals that cannot be removed from our drinking water supply and wind up in food crops and livestock grown on contaminated soil. The health risks alone are staggering. Plastic pollutants are another nonsustainable resource thats destroying the ocean habitats of sea creatures around the world- killing off fish, birds, and countless other species. Larger pieces pose choking and strangulation hazards, while the tiny particles of disintegrating plastic are making their way into the bottom of the food chain. As larger fish feed on contaminated krill, they too become contaminated and if those fish are subsequently harvested for human consumption, the contaminants are going to wind up on your plate and in your stomach. Not so appetizing, right? Fast Facts: Principles of Sustainability There are three principles which define sustainability in any type of material, as described by the American ecologist and economist Herman Daly:  Nonrenewable resources should not be depleted at rates higher than the development rate of renewable substitutes.Renewable resources should not be exploited at a rate higher than their regeneration levels.The absorption and regeneration capacity of the natural environment should not be exceeded. Renewable Energy vs. Nonrenewable Energy Nonrenewable energy resources include nuclear, hydrogen, coal, natural gas, and oil. All of these currently fail the definition of sustainability in one way or another but most painfully in the ability of the environment to absorb and regenerate the expenses related to their extraction or production.   One of the best-known examples of green technology is the solar cell, which directly converts energy from natural light into electrical energy via the process of photovoltaics. Generating electricity from solar energy equates to less consumption of fossil fuels, as well as the reduction of pollution and greenhouse gas emissions. While some detractors argue that solar panels are expensive and unattractive, new inventions may be just around the corner to offset these concerns. Community solar groups, in which renters will share solar panel products, and new spray-on photovoltaic film using perovskites that have the potential to convert regular window glass to solar collectors are just two possibilities on the horizon that show great promise for the future of solar assets.   Other renewable energy sources include hydro, biomass, wind, and geothermal, but unfortunately, these assets are not currently be exploited at adequate levels to replace nonrenewable sources. Some members of the energy industry are dead set against going green, while others see it as both a challenge and an opportunity.  The bottom line is that while non-renewable energy resources currently comprise 80 percent of the worlds energy requirements, over time, thats simply not going to sustainable.  If we hope to maintain life on our planet, emerging green energy technology must be used alongside existing methods to transition from the unsustainable to the sustainable. The Power of Positive Green Thinking Here a just a few reasons why going green is in everyones best interest: Inventors should know that green inventions and clean technologies are good business. These are fast-growing markets with growing profits.Consumers should know that buying green inventions can reduce energy bills and are often safer and healthier than non-green counterparts.  Even making small changes can have a large-term impact. For instance, consider the waste created by plastic water bottles. Of course, drinking lots of water is a healthy practice but changing out reusable water bottles for disposable ones is health-promoting, eco-friendly, and green.
