Which of the following is listed as an environmental issue affecting livestock production?

• A. Global warming
• B. Melting polar ice
• C. Overfishing
• D. Urbanization

Answer: (A)

Rising temperatures and climate shifts directly impact livestock by causing heat stress, reducing forage and water availability, and altering disease patterns. Global warming describes these broader climate changes and is the environmental factor commonly listed as affecting livestock production because it creates the main stresses producers must manage.

The other options aren’t direct environmental pressures on livestock in the same way: melting polar ice is a symptom of global warming rather than a separate management issue; overfishing concerns aquatic ecosystems; urbanization is a land-use trend that can influence agriculture but isn’t an environmental factor affecting livestock production as such.
