Garbage can significantly impact the Earth's ecosystem, including polluting air and water, harming wildlife, and contributing to climate change through the emission of greenhouse gases.
Garbage often emits an unpleasant odor due to the decomposition of organic matter, which releases gases such as ammonia, hydrogen sulfide, and methane. These gases have strong and distinct smells that contribute to the foul odor associated with garbage.
Trash dumped at a landfill is compacted and buried under soil layers to reduce odor and prevent pests. Over time, the waste decomposes and releases gases, which can be captured and used as a source of energy.
Trash and recyclables are separated to ensure that materials that can be recycled are not sent to a landfill, where they will take up space and contribute to environmental problems. Recycling also conserves natural resources and reduces the need for new materials.
