There are many ways that recycling helps the environment, and even the smallest step can have significant results.

The environmental problem of landfills is a difficult issue to fix. As more waste is put into landfills, the bigger the problem gets. Wastes that are not biodegradable or are slow to decompose can remain in landfill sites for centuries, often emitting gases that could be harmful to the environment. Keeping paper out of landfills is just one way that recycling helps the environment.

Recycling items often uses less energy than manufacturing products from natural sources. Making paper that is using recycled pulp, for instance, is much less energy intensive than using new wood. While there are benefits to growing trees because of the carbon dioxide that they consume, it will be the damage that is done to the environment by putting paper in landfills and using energy to produce new items.

Waste in landfills emit gases as it rots. This can pollute the environment. Anyone who has passed a landfill site during hot weather will be familiar with the unpleasant smell and flies that can be found near a landfill site. Reducing the items in landfills will help to reduce the pollution that it causes. Recycling wastes also typically emits less carbon dioxide and carbon monoxide, thus reducing the carbon footprint of a product.

Another benefit of recycling is that there is often a significant cost saving to be made when using recycle goods. Recycling leaves and grass, for instance, is a great way to make compost. Using homemade compost is obviously a lot cheaper than buying compost and this is a useful way to save money. Saving money through recycling ultimately helps the environment.

Recycling is just one of many ways that we can help the environment. Every step that we take, however small, is one more towards helping and supporting the environment in which we live. Getting everyone involved, from children to adults, can help produce a better environment for many generations to come.
