TED-ED: Do we really need pesticides? - Fernan Perez-Galvez

The video discusses the history and impact of pesticides in agriculture, starting with historical agricultural catastrophes and the introduction of chemical pesticides like DDT. It highlights the challenges of pesticide resistance and environmental impact, and explores future pest control strategies, including natural and technological solutions.

What was one of the main reasons for the introduction of pesticides in agriculture?

• To increase crop diversity

• To prevent agricultural catastrophes like the Irish famine

• To improve the taste of food

• To reduce the cost of farming

Which ancient method did Chinese farmers use to protect their crops?

• Sprinkling copper treatments

• Burning crops

• Using drones

What was a significant consequence of using DDT in agriculture?

• Resistance in insects

• Increased crop yield

• Improved soil quality

• Enhanced plant growth

What is a 'super bug' in the context of pesticide use?

• An insect resistant to multiple insecticides

• A bug that is beneficial to crops

• A bug that spreads diseases

• A genetically modified insect

Why is the use of pesticides still prevalent despite their risks?

• They are the cheapest option available

• They are the only method to control pests

• They are currently the best option against major agricultural disasters

• They have no environmental impact

What is one of the modern technological solutions being explored for pest control?

• Relying solely on natural predators

• Increasing the use of DDT

• Employing drones for targeted spraying

• Using more potent chemical pesticides

What is the goal of finding alternative pest control strategies?

• To eliminate all pests

• To balance food production with environmental concerns
