more civilization is developing, the greater the ecological problems are becoming. air and water pollution by industry is now reaching tremendous proportions. in our era it is changing from a national to an international problem, especially in territories where riv-ers cross several countries. the
seas and oceans are also becoming seriously polluted. a similar situation is developing in the atmosphere. it is known that many cities throughout the world suf-fer from air pollution. however, our scientific knowledge and technological advancement make it possible to eliminate it if people use good
will1 and make considerable investments for that purpose. the development of natural resources on a global scale is already possible from a scientific and tech-nical standpoint2. large-scale experimental work in this area is successfully being carried out. at present scientists in industrially
developed countries are working on the theory of inter-action of all the atmospheric and oceanic global processes that determine the climate and weath-er of the world. increasing growth of population, industrialization and the use of resources are slowly but surely changing the global climate and
water balance. this can be described as a great experiment, one that may bring about changes in the environment more serious than ever before. the essential feature in the environment protection is that many problems can be solved only on the level of world community3. therefore, the planning of
protection against pollution by human society as a whole4 is imperative today and in the near future. it is necessary to devel-op an international program to study data on land, forest, atmospheric and oceanic resources, both renewable and nonrenewable. it is the joint efforts of many scientists and
special public or-ganizations that can deal with the problem and take necessary measures to protect the environ-ment. it is still a big job and much remains to be done5. however, scientists are confident that planned actions of all countries can eliminate pollution and achieve successes in purifying
air, water and soil and in safeguarding natural resources. at the same time one must realize that so-cial and political circumstances may stand in the way of further progress in this field.
