Biological Conditions

The biological conditions can be improved by manipulating the nature of crops and animals and improving the production environment. The most important way to manipulate the nature of crops and animals is by developing new varieties that give a higher yield or production, are more resistant against pests and diseases, more tolerant of drought, etc. The development of new varieties is possible through crossbreeding of plants and animals and biotechnology.

The production environment can be improved by animal and plant production engineering (see Vols. II and III of this Handbook). The production environment also can be improved by fighting pests and diseases through animal and plant production engineering and management, development of new varieties, and the use of pesticides and vaccinations.
