Get ready to celebrate World Soil Day on December 5 and show some appreciation for the amazing soil that sustains us! This special day was established by the United Nations in 2002, when they declared it a “symbol of our commitment to sustainably manage soils as a critical component of ecosystem services.” The importance of soil cannot be overstated; it is essential for growing food, filtering water and storing carbon.

How to Celebrate World Soil Day

Plant a tree

Planting a tree is one of the best things you can do to celebrate World Soil Day. Not only does it help keep soil healthy and fertile, but it also provides much needed oxygen for our planet.

START

Start a compost bin

Composting is another great way to celebrate World Soil Day. By composting, you’ll be helping to reduce waste and create nutrient-rich soil for your garden.

VOLUNTEER

Volunteer with a local organization

There are many organizations that focus on soil conservation, and volunteering with one of these groups is a great way to show your support for World Soil Day. You could help with planting trees, cleaning up local parks, or educating people about the importance of soil health.

ORGANIZE

Organize a beach clean up

Organizing a beach clean up event is another great way to celebrate World Soil Day. Not only will you be removing harmful pollutants from entering our oceans, but you’ll also be keeping our beaches and coastal areas clean.

EDUCATE

Educate yourself

Finally, make sure you take some time to educate yourself about the importance of soil conservation and how it affects our planet. There are many books, documentaries, and websites available on this topic – so there’s plenty of information out there to get started with!

WHY THIS DAY MATTERS

Why World Soil Day is Important

Soil protects biodiversity

Healthy soils are an important part of maintaining the balance of nature. They provide habitat for many species of insects, animals, and plants, and without them, biodiversity would be greatly endangered. Protecting soil is one way to keep our planet's ecosystems thriving.

Soil helps grow food

Our soil provides us with the foundation for growing healthy fruits and vegetables. It's also the main ingredient in making bread, a staple food around the world. Without healthy soil, we wouldn't have access to these nutritional sources.

Soil captures carbon

Soils act as natural carbon sinks; they store three times more carbon than plants and four times more than the atmosphere. Keeping soils healthy helps lessen the effects of climate change by storing excess carbon, which can help protect our planet from future environmental damage.
