World is changing, and the quality and quantity of the known fuels is changing as well. However, the greatest change can be experienced in our surrounding, set in train and kept in development by our civilization. Therefore, the climate of the earth is changing in an accelerating way, and
we can only estimate to the best of our present knowledge what the near future will hold for us. Today the necessity of changing our habits is absolutely clear, otherwise these proceedings become irreversible, endangering our being.
We shall approach the possible answers from two sides: on one hand the applied systems, materials must be changed by preferring the technologies of lower environment loading, on the other hand, we shall change our approach and habits; it means we shall live more environment consciously and instruct our children in this as well. These efforts shall be enforced in our everyday life too; they shall appear in our job and private decisions and in the decision supports.
