The principle that everything we need for our survival and well-being depends on our natural environment is called "sustainability." Sustainability is the idea that we should use resources in a way that does not deplete or harm the environment, ensuring that future generations can also meet their needs.
1. **Explanation of Sustainability**: Sustainability focuses on meeting the needs of the present without compromising the ability of future generations to meet their own needs. It involves balancing economic, social, and environmental factors to ensure long-term well-being.
2. **Example**: An example of sustainability is the use of renewable energy sources like solar or wind power instead of fossil fuels. By using renewable energy, we reduce greenhouse gas emissions and minimize environmental impact, thus ensuring a sustainable energy future for generations to come.
In this case, the correct answer is **sustainability** because it directly relates to the idea that our survival and well-being are tied to the health and preservation of our natural environment.
