"In a finite world this means that the per capita share of the world's goods must steadily decrease"

This quote by Garrett Hardin suggests that in a limited world, the quantity of resources offered to each individual need to decrease over time. This is because the population is growing, however the quantity of resources offered is not. As the population increases, the amount of resources readily available to each individual decreases. This suggests that the resources should be shared among more individuals, leading to a reduction in the per capita share of the world's goods. This is a stark suggestion of the significance of managing resources properly and sustainably, as the resources readily available to us are limited and should be shared among an ever-growing population. Hardin's quote serves as a warning that if we do not handle our resources properly, the per capita share of the world's goods will continue to reduce, causing a reduction in lifestyle for everybody.
