Check understanding

• Describe how a managed environment controls conditions (e.g. a greenhouse controls temperature and water; irrigation supplies water in dry areas)
• Explain why producers manage environments (e.g. year-round supply, protection from pests and weather, higher yield)
• Evaluate one sustainability impact of a managed environment (e.g. water use from irrigation, waste from aquaculture) and a way producers reduce it

“Could your child explain why tomatoes are often grown in greenhouses or why farms in dry areas need irrigation — and one downside for the environment?”
