This paper deals with the environmental health problems in which you have to answer some questions in detail that entail the following aspects:

• Factors that contribute greatly to death and disability within low and middle-class countries.
• The significant causes of death and disability within low and middle-class countries in the 2020 and beyond.
• The possible actions taken over the next decade at national and international levels.
• The factors that allow the implementation of the actions.
• Features of environmental health problems.
• The importance of consequences of disruption of human habitat.

What are the leading risk factors that contribute to death and disability in low- and middle-income countries, and how do they differ from those found in high-income countries?

Given current trends in risk factors, what re likely to be the major cause of death and disability in low- and middle-income countries in the 2020s and beyond? Which policies and actions taken over the next decade at national and international levels could influence these trends, and which factors might facilitate their implementation.

What are the characteristics of particular environmental health problems that render them more, or less, tractable to amelioration or elimination?

As the scale of human impact on the global "environment" increase, people become more concerned about the consequences of disruption of our "habitat." What does this signify?
