Analysis Of Environmental Pollution With Multivariate Statistical Techniques

摘要

Environmental problems constitute a serious threat, both domestically and globally.These problems are related to energy use and CO_2 emission caused by agricultural and industrial activities.In this study, 30-year data was used and 37 countries were grouped in terms of environmental pollution with multivariate analysis. While most of the countries were in the same group in the 1970s, as they are now, the number of each group increased in the following years.Between 1983 and 1992, the developed countries France, Great Britain, Germany and Japan were in one group.However, in the last decade, the number of developed countries suffering from environmental pollution caused by industrialization has increased from 4 to 22.While the numbers of countries in each group has changed during the last three decades, the United States has been unique as it is a separate country in terms of pollution level. The information as to how the countries were grouped for the last three decades in terms of environmental pollution is a significant indicator, especially for the developing countries.Based on these results, the countries should change their energy sources and prepare an action plan for the next decades to decrease pollution level.
