The period from 900 AD until 1700 AD at Easter Island is an example of Overshoot and Collapse System Archetype. Around 900 AD, the island had a small population which grew over time alongside rampant consumption of island’s natural resources.  Natural resources depleted to such an extent that it could not sustain the high population resulting in a population crash amid wide spread starvation. Main events that occurred during this period are provided in the book Collapse: How Societies Choose to Fail or Survive by Jared Diamond.

The model attempts to retrace the history of Easter Island from the time people first settled on the island i.e. 900 AD until 1600 AD.

This is a clone of "Fast Fashion ISCI 360 Solutions Final submission" created by user "V B" which we are using as the foundation for an exercise in the DTU course 12100 "Quantitative sustainability".

The model takes into account clothing production and textile waste on a global scale while incorporating Vancouver's own "Fast Fashion" issue into the model.

Please refer to the notes for each variable and stock to see which links were hidden from the model.

Part 2: Our solution for the issue surrounding "Fast Fashion" focuses on increasing individuals education about sustainability and how they can help reduce negative impacts on the environment by shopping less, recycling and donating. This effect of education on sustainability is seen in the "Online Shopping" equation where the impact of "Education on Sustainability" is increased by x1.5 which impacts the entire model. Furthermore, components of the feedback loop on the right are also influenced by increasing education on sustainability and thus, those values were altered accordingly. These values were chosen arbitrarily by taking into account that doubling any value is not realistic so the change should be between x1.0 and x2.0.
