What was a primary reason for the shift from open town dumps to carefully managed landfills?
- The introduction of recycling programs made open dumps obsolete.
- Increased waste production due to population growth and more elaborate packaging. (correct)

Why is it essential to manage landfills carefully, especially in relation to the ground on which they are located?
Why is it essential to manage landfills carefully, especially in relation to the ground on which they are located?
- To mitigate the risk of groundwater contamination due to the typically porous ground. (correct)
- To ensure the structural integrity of the landfill and prevent collapses.
- To facilitate the extraction of valuable minerals from the waste.
- To maximize the land's aesthetic appeal and prevent visual pollution.
How do modern landfills address the issue of methane gas production from decomposing organic waste?
How do modern landfills address the issue of methane gas production from decomposing organic waste?
- By releasing it into the atmosphere in a controlled manner.
- By using chemical neutralizers to prevent its formation.
- By ignoring it, as the gas naturally dissipates over time.
- By collecting and processing the gas to be sold as fuel. (correct)

Study Notes
- Society once had little concern for garbage disposal due to less waste.
- People were more frugal and items were less packaged.
- Garbage ended up in town dumps, which people avoided due to unpleasant conditions.
- Land was plentiful and populations were smaller.
- Increased population led to more waste and complex packaging.
- New methods for waste disposal became necessary.
- Recycling helps, but isn't a complete solution.
Changes in Waste Disposal
- Old town dumps are being replaced by large, managed landfills.
- The world's largest landfill was in Staten Island, serving New York City.
- It processed over 10,000 tons of waste daily, covering 3,000 acres and rising 500 feet.
- Landfill was designed for 5 years but lasted for over 50 years, closing in March 2001.
- Landfills require careful management to protect groundwater.
- Linings of plastic or clay prevent seepage into the ground.
- Methane gas from decomposing waste is captured and sold as fuel.
- Captured gas sales reduce landfill costs.
"Mount Trashmore" Example
- The Riverview Highlands Ski Resort near Detroit was built on a landfill.
- It had eight slopes and was affectionately called "Mount Trashmore" by locals.
- Soil layers were added to bury the trash as the landfill grew.
- Grass was planted upon completion, creating an amenity for local residents.
Landfill Capacity and Challenges
- Scientists say fears of running out of landfill space are a fallacy.
- Challenges arise, like the furor over Styrofoam in the 1980s.
- Concerns about Styrofoam led fast-food companies to switch to paper packaging.
- Some scientists argue that paper lasts just as long as plastic.
The Garbage Project
- Begun in 1973 at the University of Arizona.
- Aimed to gather data due to a lack of accurate information on garbage.
- Researchers sifted through garbage, separating it into 200 categories.
- Analysis of landfills provides insights into modern lives.
- Researchers call themselves "garbageologists".
- They offer knowledge to plan for the future.
