Problem Research Ideas:
1.Recognize the ecological footprint.
2.Understand the size and trends of the global ecological footprint.
3.Calculate and analyze your personal ecological footprint.
4.Propose action plans to reduce the ecological footprint of individuals.
Question 1:
1.Explain the relationship between the size of the ecological footprint and the amount of resources consumed.
2.How does the size of the ecological footprint affect the service functions of the natural environment?
Analysis: 1Ecological footprint means biologically productive area of land that is necessary to sustain the survival of an individual, region, country or globe or that can accommodate only human wastes. It is also called "proper carrying capacity". The larger the ecological footprint, the greater the resource consumption, and the smaller the ecological footprint, the smaller the resource consumption, and the two showed a positive correlation.
2.Ecological footprint refers to the area of biologically productive land that is necessary to sustain the survival of a person, region, or country, or that can accommodate the waste emitted by humans. The service function of the natural environment refers to all the benefits that human beings obtain from the ecosystem, the more resources obtained from the natural environment and the more waste discharged, the greater the impact on the environment, the more serious the damage to the ecology, if it exceeds the scope and degree that the natural environment can bear, the service function of the natural environment will be damaged, so the larger the ecological footprint, the service function of the natural environment will decline.
So the answer is:1The larger the ecological footprint, the greater the resource consumption (positive correlation).
2.The larger the ecological footprint, the greater the amount of resources obtained from the natural environment and the amount of waste discharged, the greater the impact on the environment, the more serious the damage to the ecology, and if it exceeds the scope and degree that the natural environment can bear, it will damage the service function of the natural environment.
Material 2 Question:
1.Describe the characteristics of changes in the global ecological footprint, and indicate the years when the global ecological footprint exceeds the carrying capacity of the earth.
2.What impact do lifestyle choices have on future trends in the ecological footprint?
Analysis: 1According to the information on the map, since 1960, the ecological footprint has shown a steady upward trend, in 1970 the ecological footprint is equal to the number of one earth, after 1970, the ecological footprint exceeded the carrying capacity of the earth, in the ecological deficit.
2.The horizontal axis is the year, and the broken line is divided into two situations around 2015, the upper part is the production and lifestyle that does not recognize the change, and the lower part is the reduction of 30% carbon emissions, indicating that reducing carbon emissions can effectively reduce the ecological footprint; Choosing different lifestyles will have different impacts on the future ecological footprint; If you choose a high-consumption lifestyle, you will consume a large amount of resources, and your ecological footprint will further increase in the future. Choosing an environmentally friendly lifestyle will slow down the growth of the ecological footprint in the future.
So the answer is:1Characteristics: Overall upward trend; After 1970, the ecological footprint exceeded the carrying capacity of the planet; If carbon emissions are reduced, the ecological footprint decreases. Year: 1970 onwards.
2.If you don't change your lifestyle, your ecological footprint will continue to grow in the future, and if you reduce carbon emissions by 30 percent, your ecological footprint will remain small.
