Landfills don’t just releases gases, either; they release liquids. The most potent of these, perhaps, is leachate, which can contaminate underground water sources.
In addition, landfills require large amounts of land space–millions of acres both in the United States and worldwide. When landfills reach their capacity, there are but two options: one, make them bigger, or two, simply build more. Unfortunately, all landfills will eventually reach their capacity, and when they do, they don’t disappear; they remain full of our waste.
Essentially, a landfill is a large, full trash bag that just sits in your kitchen. As more bags accumulate, your kitchen will become full and inhospitable.
As a result, recycling is always a better option than landfills when it comes to waste management, especially since virtually any form of waste can be recycled.
