"The natural capital is not income, but we spend our natural capital as if it were revenue, as if it were going to come back next year without any problems, whereas these renewals in nature can take hundreds of years"

This quote by Susan George is a warning about the unsustainable use of natural resources. She is saying that natural capital, such as forests, minerals, and water, is not an income, however rather a limited resource that requires to be handled responsibly. We frequently deal with natural capital as if it is a limitless resource, spending it as if it will be replenished without any repercussions. However, some natural deposits, such as forests, can take centuries to restore. For that reason, it is essential to be mindful of our use of natural capital and to guarantee that we are not depleting it much faster than it can be replenished.
