     Most of the 20th century has been a development on the Industrial Revolution taken to an extreme: people

now own more products than ever before; there are enough nuclear weapons to destroy the earth several times

over; there is hardly any forest left and pollution has got to the point where we buy water. Within a few years

I predict you will be able to buy air. (There once was a time when you didn't need to buy food or shelter either.) 

     Important developments in the last century are the breaking down of the class structures left over from the

Industrial Revolution stage, bringing with it the empowerment of the "common man": the working day is set by

law to only 8 hours a day, everyone has the vote, the media has less obvious government control, people have

landed on the moon, sent spacecrafts to Mars and so on. Families have also shrunk drastically (强烈地); the

nuclear family came about, and especially in the last half of the 20th century, one-parent families are becoming

more common. This shrinking in the size of the family shows the increased independence of people-once upon

a time people had to live in large groups to survive.

     As humans have "become the gods", they have realized their individuality and independence and taken their

control of the world to an extreme. In many countries the land is almost completely used in the production of

food and as living space and they live in small cities which are entirely human constructed, made from materials

which are also entirely human constructed (concrete, bricks) with hardly any remains of nature. Weeds are

poisoned because they are messy; even parks have trees grown in tidy lines; grass is mowed to keep it short

and so on. I think the massive drug "problem" troubling people is a result of too much of this influence, humans

needing to escape the stark world they have created by entering fantasy worlds.

     Over the last 100 years, the 20th century consciousness has spread throughout the world; most of Asia has

been thoroughly "Westernized", and most of the Third World is being overrun by Western ways of doing things

and living.
