...about inventions

Day by day scientists discover and develop new things, new inventions... Each year there appear more and more inventions...
From ancient times, people are eager to discover things that will facilitate their activities and their life.

Here are some of them:
1.65 million years BC - the invention of axe
1 million years BC - possession of fire
50000 BC - bow and arrows
VII century - windmill
1608 - telescope
1827 - matches
1952 - thermonuclear bomb
1960 - laser
Now goes the III millennium:
2000 - prototypes of robots for household
2002 - artificial retina
2007 - transducer mechanical vibrations into electrical energy
and more...

And each next invention is more complicated than the previous...

People now can cure diseases, can predict the natural disasters, can fly, but.....
...they also create the most dangerous viruses, chemical weapons, nuclear bombs, capable to kill millions of families and to destroy whole continents...

Why when famine soon will cover all the regions of the Earth, people are thinking about inventing another kind of mass destruction weapon?
Why when greenhouse effect threatens the whole living on the Earth, people think about their pockets and "stifle" the new inventions which are capable to make the surrounding atmosphere healthier?
Why when there is a risk that our children would be able to see some animal species only on pictures, now people are hunting for their trophies?

We vote for democracy, for liberty, but more and more destructible weapons are created daily.
We vote for peace, but there is like a preparation for a war.
We strive for excellence, but... where is that excellence?

Just think what if all the scientists were focused on a different from weapons issues? The life would be more beautiful and fearless. Actually it is so now, only if do not thinking about all the destructive things a human has create...
