Modern Agriculture and Fishing

Intensive farming uses modern practices to increase food production efficiency, necessary due to population growth. It offers benefits like higher yields and food security but raises environmental and animal welfare concerns. Energy efficiency is improved by reducing energy loss in food chains. However, the use of chemicals in crop farming and modern fishing techniques have negative environmental impacts.

What is one of the main reasons for the increased use of intensive farming?

• To improve animal welfare

• To feed a growing population with limited land

• To increase the variety of crops

• To reduce the number of farm workers

Which of the following is a benefit of intensive farming?

• It requires more labor

• It can produce food all year round

• It reduces the need for fertilizers

• It allows for seasonal food production

What is a disadvantage of using fertilizers in intensive farming?

• They improve soil quality

• They increase labor costs

• They reduce crop yield

• They can cause eutrophication

How does intensive farming improve the efficiency of food production?

• By reducing energy transfer to the environment

• By allowing animals to roam freely

• By using natural diets for animals

• By increasing the space for animal movement

What is a consequence of keeping animals in small pens in intensive farming?

• Increased animal welfare

• Reduced risk of infection

• Increased stress and infection risk

• Improved natural behavior

What is a negative effect of pesticides used in intensive farming?

• They improve crop resistance

• They bioaccumulate and become toxic

• They increase plant growth

• They reduce water pollution

What impact have modern fishing techniques had on aquatic ecosystems?

• Improved water quality

• Overfishing and ecosystem damage

• Reduced fishing efficiency

• Increased fish populations
