Question

1. comparison: what is a conceptual model? then explain the two conceptual models listed

conceptual model
limits - to - growth thesis
cornucopian thesis

1. draw conclusions: using pp. 34 - 35 and what you have read in this section, explain why there has been a growing need for sustainable development in recent years. bonus: research how many earths are needed to give every person on our planet alive today the same lifestyle as someone in a medc.

Explanation:

A conceptual model is a representation of a system using concepts and ideas to help understand, explain, or predict how the system works. The limits - to - growth thesis posits that there are finite limits to Earth's resources and that continued economic and population growth will eventually lead to collapse. The Cornucopian thesis, on the other hand, argues that human ingenuity and technological progress will overcome any resource limitations and that there are no real limits to growth. For the need for sustainable development, factors such as resource depletion, environmental degradation, and social inequality have contributed to the growing recognition of its importance. As for the bonus question, the ecological footprint concept is used to calculate how many Earths would be needed if everyone lived like those in a More Economically Developed Country (MEDC), and it often shows that current consumption patterns are unsustainable.

Answer:

Conceptual Model: A representation using concepts to understand a system.
Limits - to - growth thesis: Argues finite resources will lead to collapse with continued growth.
Cornucopian thesis: Claims human ingenuity will overcome resource limits.
For the need of sustainable development: Due to resource depletion, environmental degradation, social inequality etc.
Bonus: Calculated via ecological footprint concept showing unsustainable consumption in MEDCs.
