Landfills

The video discusses the significant amount of waste humans produce and the importance of waste management. It explains how waste is managed through incineration and landfills, highlighting the environmental impact of landfills, such as leachate and methane production. The video also addresses the challenges of landfill space and the necessity to reduce waste to prevent future issues.

Why is waste management considered a major industry?

• To create more jobs in the economy.

• Because it generates a lot of revenue.

• To prevent waste from piling up and causing health hazards.

• It is a new trend in urban planning.

What is leachate, and why is it a concern?

• A type of plastic used to line landfills.

• A harmless gas produced by organic waste.

• A liquid formed from decomposing waste that can be toxic.

• A type of soil used in landfills, which is expensive.

How can methane from landfills contribute to environmental issues?

• By increasing the acidity of rainwater.

• By reducing the oxygen levels in the air.

• By trapping heat in the atmosphere and contributing to global warming.

• By causing soil erosion.

What is a significant challenge associated with landfills?

• They decompose waste too quickly.

• They are expensive to build and space is limited.

• They are not visible to the public.

• They are too easy to build.

What is a potential solution to the problem of limited landfill space?

• Increasing the size of existing landfills.

• Exporting waste to other countries.

• Reducing the amount of waste sent to landfills.

• Building more incinerators.
