Increasing food supply

What is the main reason for the uneven distribution of food supply?

• Increased population growth

• Uneven distribution and consumption rates

• Lack of technology

• Decrease in food production

What is irrigation?

• The natural watering of the land

• A method of harvesting crops

• The artificial watering of the land

• The process of cleaning water

What is the purpose of using appropriate technology in LICs?

• To help increase output while keeping costs down

• To decrease food production

• To import food from other countries

• To increase the cost of food production

What did the Green Revolution in the 1950s and 60s focus on?

• Decreasing the supply of food

• Increasing the use of traditional farming methods

• The development of technology and new strains of plants to increase food supply

• Reducing the population growth

What are GM crops modified to do?

• Require more water

• Increase CO2 emissions

• Decrease nutritional values

• Need less water and be disease resistant

What is a concern regarding GM crops?

• They require more water

• They decrease food production

• They are less nutritious

• They can interbreed with wild plants and disrupt local ecosystems

What does hydroponics involve?

• Growing plants in the air

• Growing plants in soil

• Growing plants in mineral-rich water or growing medium

• Spraying plants with pesticides

What is a benefit of aeroponics and hydroponics?

• They are suitable for all types of crops

• They have a low set-up cost

• They allow for growth all year round

• They require a lot of water

What is a drawback of high-tech farming methods like aeroponics and hydroponics?

• They are not effective in increasing yields

• They have a high set-up cost

• They can only be used in tropical climates

• They reduce the nutritional value of crops

Why is it vital to use both large-scale and small-scale methods to improve our global food supply?

• To increase the cost of food production

• To reduce the global population

• To make farming more difficult

• To maintain our supplies of food
