Does Clean Mean Extreme Green?

By Bill Knell

Growing up inrepparttar suburbs of New York City inrepparttar 134920 1960s was a pleasurable experience. Venturing into New York City, especially Manhattan, was not. The smell of car, truck and bus exhaust combined with a number of other foul vapors to produce a pollution mix that almost seemed toxic. If you were used to it,repparttar 134921 city air was probably something that you were able to tolerate. However, to those who spent more time out ofrepparttar 134922 city then in it,repparttar 134923 air was filthy and made you sick.

Byrepparttar 134924 late 1970s,repparttar 134925 air quality in Manhattan andrepparttar 134926 other Boroughs improved substantially. There were a number of reasons for this including clean air initiatives and vehicle emission reductions. The city was also a much cleaner place. Concerns about pollution and living in a better environment caused people to clean up their neighborhoods. Dumping of materials into waterways was more tightly regulated or stopped altogether. Antiquated garbage and environmental facilities operated by New York City were updated or completely rebuilt. Anti-littering campaigns made us all think twice before throwing garbage onrepparttar 134927 street.

The cleaning up of New York City was not an isolated incident. Cities and towns throughoutrepparttar 134928 United States became aware that a large part of their image and identity depended on how clean they were. However, this is not a new phenomenon. Whenever public health has been threatened by a lack of good environmental practices, there have been clean ups. Most large cities throughoutrepparttar 134929 world have made sincere efforts to clean up their streets, waterways and neighborhoods. Municipal facilities that have to do withrepparttar 134930 environment have been updated.

As we began to take a closer look atrepparttar 134931 environment, it became obvious that good stewardship of our planet produced positive consequences. By replanting forests that were cut down, we insured a future supply of lumber and made sure that those areas were not impacted in a negative way. When limitations were placed on fishing in various areas,repparttar 134932 future catch and survival of creatures necessary to those eco systems were guaranteed. Artificial products were combined with natural materials to produce superior textiles that were less expensive and eco friendly. The government limitedrepparttar 134933 use of dangerous chemical pesticides which posed a threat to everything.

Despite allrepparttar 134934 positive results from a world of people who became more environmentally conscience, something went wrong. The movement to clean uprepparttar 134935 earth and be good eco stewards changed. It became a screaming protest against disturbingrepparttar 134936 world in any way. Things like logging, use of animals for food or clothes and drilling for oil were no longer going to be tolerated. Environmentalists wanted to put an end to human domination ofrepparttar 134937 planet. The old enemy was large corporations that saved their bottom line atrepparttar 134938 cost ofrepparttar 134939 cleanliness and safety of communities where they operated factories. The new enemy is us!

The Impossible Machine

Written by Jim Henderson

There are a lot of complicated machines inrepparttar world today. Some are marvels of design and engineering. Only a few years ago, they would have seemedrepparttar 127722 stuff of science-fiction. Nothing invented today will be likerepparttar 127723 machine that I’m going to build.

I’m going to build a machine. It will be extremely complex, more than a television, or a VCR, or even a computer. This machine will be so complex that it will contain volumes of complicated information locked in a special code. Oh, and it operates itself, that’s right! It doesn’t need someone to “run” it.

What if I told you that it that it will be so smart that it can even repair and replace itself so it will never wear out? Even complicated machines wear out and have to be fixed. Even these machines don’t operate themselves. But mine will! Wouldn’t you like to have a car like that? Did I mention that it will even reproduce and replace itself. I mean it will create exact functional replicas of itself.

Sounds extremely difficult, doesn’t it? Maybe impossible is a better word. I’m still not finished telling you about my machine. This machine can “fuel” itself so it won’t need gasoline or batteries. It doesn’t run on nuclear power either.

It will be in some ways like a small city complete with it’s own transportation, manufacturing, even it own power plant. And laboratory, since it operates by complex chemical reactions, much too complex to even begin to describe here. With all this activity it will have to a waste disposal system too -- it cleans itself.

A amchine that could do all this would have to huge...wouldn’t it? So with all this, how big will it be? What if I said my machine will be miniature? So small, in fact, that it will be invisible...almost. Unless of course, you use a microscope, a very powerful one.
