In 1968, the Roman club announced a report entitled "Growth Limit", which stated that population growth leads to increased food demand and ultimately resource depletion. To prevent resource depletion, the Roman club decided that it is necessary to regulate population growth and lower birthrate. This is the goal of China's one-child policy and the unemployed population policy of Kerala State. Similarly, anti-Malthusianist-Ester Boserup is a resource optimist whose research is based on research on metastasis.
In particular, population growth is putting increasing pressure on the resources of the earth - water, forests, land and the atmosphere of the earth - which is contributing to climate change and environmental sustainability challenges. However, demographics not only affect the main development goals, they are themselves affected by social, economic and environmental changes. Demographics not only present challenges, but also provide important opportunities for more sustainable development. For example, declining birthrate and slowing population growth will result in an increase in population concentration in the working age group, which will enable each country to receive demographic dividends and to start economic development quickly.
As population continues to increase and urbanize at unprecedented speeds, new urbanization and smart growth techniques have been implemented to create a transition to a development environment, economically and socially sustainable cities. The principles of intellectual growth and new urbanism include walking, composite application development, comfortable high density design, land protection, social equity, economic diversity and so on. The multipurpose community avoids the high end through affordable housing to promote social equity, reduce the dependence of the vehicle on fossil fuel use, and promote the regional economy. The per capita GDP of the walkable community is 38% higher than the low mobility city subway (Leinberger, Lynch). By combining economic, environmental, and social sustainability, cities are more equitable and resilient than the expansion of cities that use the land too much, promote the use of cars, and economically isolate the population There will be, it will be attractive.
There is a strong synergy between health, environmental protection and sustainable resource utilization. Individuals and communities responsible for realizing a healthy environment and managing resources can continue to be partners to ensure that global cycles and systems are not compromised. Complexity theory, systematic understanding of health, flexibility of change, symbiosis, synergy, and integrated generation design, to build a comprehensive strategy to maintain human and world health and build a culture of regeneration Useful, related scale link concept and framework.
