Which practice would NOT be considered sustainable?

The practice of deforestation for urban development is an example of an unsustainable practice because it involves the clearing of forests or natural landscapes, which can lead to significant environmental degradation. This action reduces biodiversity, disrupts ecosystems, contributes to soil erosion, and increases greenhouse gas emissions by eliminating trees that would otherwise absorb carbon dioxide. Sustainable practices, on the other hand, aim to balance environmental health, social equity, and economic viability.

Using renewable energy sources, implementing waste reduction strategies, and developing green spaces are all practices designed to minimize environmental impact and promote resource conservation, making them sustainable choices that contribute positively to long-term ecological health. Deforestation directly contradicts these principles.
