⦁Why environment and human's qualify of life and economic growth has close relationship.I shall explain how this study confirms the invested correlation between economic growth and environmental degradation of hypothesis that is at the early stage economic growth which increases environmental degradation, then environmental degradation decreases after reaching a certain level of average income per capita. Moreover, I shall explain how other factors, such as trade openness, industrial extension also cause an increase in environmental degradation. This study also has been investigated the between environmental pollution and per capita income when have close relationship to influence economic falling down in long term.The key indicators are used to capture the changes in environmental conditions have been developed and used in many countries. A high rate of economic growth has been a primary and permanent goal of government and society, particularly in developing countries. The increase in economic growth is related to an increase in the production and consumption of products and services. Consequently, it may lead to an increase in the multiplied products of the people and income per capita consumption. However, economic growth may produce negative impacts on the environment pollution, overexploitation of natural resources, degradation and loss of wildlife habitat and climate change. Hence, many countries have been facing the decline in environmental quality issue when which neglect to reduce environmental pollution challenge in long term. I believe that the impact of economic growth on environment quality is categorized through three different channels: The first is the scale effect, the second is the composition and the end is the technique effect. The scale effect means to happen as pollution increases with the size of the economy, the explanation being that even of the structure of the economy and the technology doesn't change, it is assumed that an increase in the scale of economic activity leads to an increase in pollution and environmental degradation, when the composition effect refers to the change in production structure of an economy from agriculture-based to industry and service. The last effect is the technique effect, which captures improvement in the technique of production and adaption of cleaner technologies and hence a reduction in pollution⦁Explaining why the Environmental Kuznets Curve key indicator method is measured to any country's economic growth and environmental pollution relationship commonly
