Abstract
The abstract of this paper comes from the analysis of the relation between population growth and environment degradation presented by the CO2 emission. The paper focuses on many subjects based on depending the economic division of world countries, according toـ the reports of human developing which adopts dividing the world into three economic groups. The paper studies the variance of the CO2 emissions of these countries by depending on Lourenz curve of variation and extraction of Gini coefficient which reach 49.8% for the variance between countries. In addition to study the measurement relation between population and CO2 emissions for each of the groups elected. The paper also, deals with the logical analysis to evaluate conclusions of the relation between population growth and CO2 emission, which the logical explanation to the effect of increasing economic activities on the environment and in the impact of present and future generations. Besides the implication related to the rapid population growth and its effect on the available and renewable resources and the unrenewable. Finally, the research confirms, importunely, the attempt to discover renewable energy resources depending on the co-operation between countries in to present and the future stages the face the risk of the environment degradation.
