RESUMO
PIP: The results of public opinion surveys were used to assess the variation in views and attitudes toward the environment among different social strata in several countries. The developed countries have recently become concerned about the disappearance of the rain forests, but mere survival is more of a preoccupation for the majority of Brazilians than damage tot he rain forest. A survey of a representative national sample during the 1989 presidential election indicated that fewer than 10% of Brazilians considered ecological problems among the 3 major national problems. But in a survey to determine which environmental problems in Brazil were considered most serious, burning of the tropical forest was identified by the greatest proportion of respondents, 19%, followed by industrial pollution of rivers and cities, 17%. Surveys in 1990-91 in Great Britain indicated in contrast that some 92% of respondents were in favor of 1 or more measures to limit deterioration of the tropical forest, such as limiting importation of wood from countries not protecting their forests or contributing funds to ecological groups. Opinion surveys in British Columbia, whose main economic activity is forestry, showed that 40% of respondents considered ecological problems to be the most serious, ahead of unemployment, the economy, or social services. But specific questions on clear cutting of forests, preservation of old forest in Vancouver, or pollution controls for the paper industry, which closely affected the local economy, divided opinion and probably demonstrated a desire to protect the environment without too greatly disturbing the local economy. Study of the reactions of developing country populations to environmental problems is difficult because of language and cultural barriers, political instability, war, natural catastrophes, and difficulty of establishing representative samples, among other factors. Results of a study of the opinion of the Maya population of southern Mexico and northern Guatemala on deforestation, land use, and development are expected to appear shortly. A study in Lima identified the proliferation of refuse in the street as the worst ecological problem for 42%, followed by air pollution caused by automotive exhausts for 30%. Only 1% believed disappearance of the rain forest to be the principal problem. The ordering of ecological problems was significantly influenced by social class. A comparison of the views on ecological problems of opinion leaders and the general public was conducted in 1988-89 in 16 countries on 4 continents. In most cases, the opinions of the leaders corresponded to those of the general public. Most respondents in all countries except Saudi Arabia considered their environment of average quality, and a majority believed that the place where they lived had worsening environmental conditions over the past decade. Majorities in all countries except Japan stated they support organizations that protect the environment.^ieng
