TWO COURSES OF ACTION
The problem of the environment crisis has recently assumed global proportions. Both scientists and politicians agree that unless some radical steps are taken before long, life on our planet may be irrevocably damaged if not destroyed altogether. It seems therefore worth while to consider the fundamental conflict which underlies the surface manifestations of the present crisis. For there undoubtedly exists a conflict, an incompatibility between the tenets of an industrial society and those of ecology.
Industry is bound to expand continuously, all ecological systems tend toward stability equilibrium.
There seems to be at least two general courses of action which might be adopted in order that the environmental doom may be averted.
One would be to curb the dynamics of industrial development; the other - to turn technology to the construction of physiologically and socially healthy environment, the former possibility being highly unrealistic, the latter one seems to be the only path to follow.
1. Why has the environmental crisis assumed global proportions?
2. What problem worries scientists and politicians alike?
3. How can we possibly avert the destruction of the environment?
4. Can you suggest any other courses of action to protect the environment?
