If you ask what you are going to do about global warming, the only rational answer is to change the way in which we do transportation, energy production, agriculture and a good deal of manufacturing. The problem originates in human activity in the form of the production of goods.

Seen that way, the wholesale transformation of production technologies that is mandated by pollution prevention creates a new surge of economic development.

Nothing can survive on the planet unless it is a cooperative part of larger global life.

As the earth spins through space, a view from above the North Pole would encompass most of the wealth of the world - most of its food, productive machines, doctors, engineers and teachers. A view from the opposite pole would encompass most of the world's poor.

Perhaps the simplest example is a synthetic plastic, which unlike natural materials, is not degraded by biological decay. It therefore persists as rubbish or is burned-in both cases causing pollution. In the same way, a substance such as DDT or lead, which plays no role in the chemistry of life and interferes with the actions of substances that do, is bound to cause ecological damage if sufficiently concentrated.

For that reason the simple test of the slogan 'Consume Less' as a basis for social action on the environment would be to tell it to the blacks in the ghetto. The message will not be very well received for there are many people in this country who consume less than is needed to sustain a decent life.

When you fully understand the situation, it is worse than you think.
