As an expert in environmental science, I can provide you with a detailed account of what happens to plastic bags when they are discarded. Plastic bags are one of the most common forms of waste found in our environment. They are lightweight, durable, and convenient, but they also have a significant impact on our ecosystems and the health of our planet.

When plastic bags are thrown away, they can end up in several places. The primary destinations are landfills, waterways, and oceans. Let's explore each of these in detail.

Landfills: A significant portion of discarded plastic bags ends up in landfills. Landfills are designated areas for the disposal of waste materials by burial, often in layers, compacted and covered with soil. In a landfill, plastic bags do not biodegrade. Instead, they persist for a very long time. As mentioned in the reference, plastics may take up to 1,000 years to degrade. Over time, they break down into smaller pieces known as microplastics. These microplastics can leach harmful chemicals into the soil and water, contaminating the environment and potentially entering the food chain.

Waterways and Oceans: Plastic bags can also end up in rivers, lakes, and oceans. When plastic bags enter waterways, they can cause a range of problems. They can clog waterways, leading to flooding and damage to infrastructure. More importantly, they pose a significant threat to wildlife. Animals can mistake plastic bags for food and ingest them, which can lead to injury or death. Additionally, plastic bags can entangle animals, causing them to drown or suffer other physical harm.

The process of degradation in water is similar to that in landfills, but it is accelerated by the action of sunlight and water. Ultraviolet radiation from the sun and the mechanical action of waves can break down the plastic into microplastics more quickly. These microplastics are then carried by currents and can travel vast distances, affecting marine life and ecosystems around the globe.

Environmental Impact: The environmental impact of plastic bags is profound. They contribute to pollution, harm wildlife, and can have long-term effects on human health. The chemicals that leach from plastics can disrupt hormones and have been linked to various health issues, including cancer and reproductive disorders.

Recycling and Alternatives: To mitigate the impact of plastic bags, recycling is crucial. Many communities have recycling programs that accept plastic bags. However, the recycling process for plastic bags is not always efficient, and not all types of plastic bags can be recycled. Some are contaminated and must be discarded.

Alternatives to plastic bags include reusable bags made from cloth or other durable materials. These bags can be washed and reused multiple times, significantly reducing the number of bags that end up in the environment.

In conclusion, when plastic bags are thrown away, they can have a lasting and detrimental effect on the environment. It is essential to reduce our reliance on single-use plastics, recycle when possible, and seek out sustainable alternatives.
