P1C 17 New Technology and Sustainable Development in Deserts

What is the definition of sustainable development?

• Improving basic standards of living without compromising the needs of future generations

• Maximizing profits without considering the environment

• Using resources without any regard for future generations

• Promoting economic growth at the expense of social well-being

Which of the following is an example of a new sustainable technology for hot arid environments?

• Wind power

• Coal power

• Hydroelectric power

• Desalination

Why is desalination a viable solution for water scarcity in hot arid regions?

• It is a cheap and easily accessible technology

• It uses renewable energy sources like solar power

• It produces large quantities of freshwater at a low cost

• It removes salt from seawater to produce fresh water

What is a major downside of desalination?

• It harms ecosystems in the area

• It is not economically viable for poor nations

• It requires a large amount of land for infrastructure

• It relies on fossil fuels as the energy source

Why are hot arid deserts ideal places for solar power?

• They have a high population density

• They have abundant rainfall

• They have cheap land and low population densities

• They have a lack of sunlight

What is a disadvantage of large solar power plants?

• They are not cost-effective

• They require a large amount of water

• They harm wildlife like birds and insects

• They have a short lifespan

What is hydroponics?

• The process of removing salt from seawater

• The process of growing plants in nutrient-enriched water

• The process of harnessing solar energy

• The process of recycling waste materials

Why is hydroponics suitable for agriculture in hot arid environments?

• It requires a large amount of water

• It allows for year-round cultivation

• It is a low-cost technology

• It relies on traditional soil-based farming

What is a downside of adopting hydroponics?

• It is not suitable for hot arid environments

• It requires expensive technology

• It harms ecosystems in the area

• It relies on fossil fuels as the energy source

What is the main goal of sustainable development in hot arid environments?

• Maximizing profits for present generations

• Improving basic standards of living without considering future generations

• Preserving the environment at the expense of economic growth

• Improving basic standards of living without compromising the needs of future generations
