" Nobody in the developing world is going to take, as an answer to their aspirations, the developed world’s reply: ‘Sorry, you can’t; we’ve already used it all up.’ To earn the right to look the developing world in the eye and start this conversation, we need a reassessment of how we live and what we want. "
- John Lanchester

The quote speaks to the disparity between developed nations and developing countries regarding resource usage and environmental impact. It suggests that those who have already exploited a significant portion of Earth's resources cannot simply dismiss the aspirations of less privileged nations by claiming there are no remaining resources available for them to develop. This statement highlights the complex relationship between economic growth, resource depletion, and environmental sustainability.

On a deeper level, the quote reflects broader ethical questions about responsibility and equity in a world where natural resources are finite. It challenges developed countries to reassess their lifestyles and consumption patterns to ensure they contribute positively to global sustainability efforts rather than merely exploiting available resources without regard for future generations or less fortunate populations. The idea is that meaningful dialogue between nations can only occur when there is a mutual understanding of the environmental, social, and economic implications of resource use.
