Which of the following is an environmental concern related to food production?

Deforestation for agriculture is a significant environmental concern because it involves clearing forests to create space for crop production or livestock grazing. This practice can lead to a variety of ecological issues, including loss of habitat for countless species, disruption of water cycles, increased greenhouse gas emissions due to the release of carbon stored in trees, and soil erosion. Forests play a crucial role in maintaining biodiversity and regulating climate, so their removal can have far-reaching consequences for the environment.

The other options, while related to food production, do not reflect environmental concerns. Soil enrichment typically involves improving soil health and fertility, which generally benefits the environment and agricultural productivity. The reduction in food prices can have economic implications but is not inherently an environmental issue. Increased biodiversity usually indicates a healthy ecosystem, which is generally positive for the environment and food production.
