10 Essential Reasons Why Forests Matter to People and the Planet
Forests sustain biodiversity, regulate climate, and provide invaluable resources for all life on Earth.
Forests have always been a foundation for human civilization and the diversity of life on Earth. Whether as a source of materials, a haven of biodiversity, or an engine of climate regulation, forests profoundly influence the planet. Yet, in an era of ongoing deforestation and environmental change, understanding why forests are important has never been more urgent. This article explores ten fundamental reasons why forests matter—to people, wildlife, and the ecological systems that sustain our world.
1. Forests House the Majority of Earth’s Terrestrial Biodiversity
Forests are irreplaceable as reservoirs of life. Despite covering only about 31% of the Earth’s land area, forests are home to over 80% of the world’s terrestrial species. From jaguars stalking South American rainforests to millions of invertebrates thriving in leaf litter, forests provide complex habitats that support:
- Mammals, birds, reptiles, amphibians, and insects
- Vast arrays of plants—from giant trees to understory ferns
- Myriad fungi, lichens, and microorganisms critical for healthy soils
In tropical regions, rainforests serve as particularly rich cradles of evolution. But temperate and boreal forests possess similarly intricate webs of life, each with species adapted to their unique climates and conditions.
2. Forests Regulate the Global Climate
One of nature’s most powerful climate tools, forests absorb and store vast amounts of carbon dioxide. Through photosynthesis, trees absorb CO2 and release oxygen, a process that mitigates atmospheric carbon pollution. Key contributions include:
- Acting as carbon sinks, storing up to 861 gigatons of carbon worldwide
- Helping regulate temperatures locally and globally
- Mitigating the effects of greenhouse gases and climate change
Deforestation releases stored carbon, exacerbating climate change. Forest preservation and restoration are therefore central to global efforts to slow global warming.
3. Forests Provide Clean Air and Oxygen
Trees and forests produce a significant portion of the planet’s oxygen, thanks to photosynthesis. Additionally, forests act as the planet’s natural filters, as they:
- Absorb pollutants such as nitrogen oxides and sulfur dioxide
- Trap dust, ash, pollen, and smoke on their leaves, reducing airborne toxins
- Improve overall outdoor air quality, especially in urban environments
The widespread presence of trees means cleaner, healthier air for millions, preventing respiratory illnesses and supporting the welfare of all living creatures.
4. Forests Safeguard Water and Prevent Flooding
Forests play a critical role in regulating water cycles and protecting watersheds. Their root systems stabilize soil, which:
- Prevents erosion and landslides
- Enables water infiltration and groundwater recharge
- Slows surface runoff, reducing the severity and frequency of floods
- Filters and purifies water before it reaches rivers, lakes, and reservoirs

Moreover, forests help moderate rainfall patterns, reduce drought impacts, and maintain the flow and quality of water vital for both people and ecosystems.
5. Forests Are Vital for Livelihoods and Economies
Many communities—especially in the Global South—depend directly on forests for survival and income. Forests provide:
- Timber and non-timber products such as resins, nuts, fruits, and fibers
- Medicinal plants that form the basis for healthcare for millions
- Sustainable ecotourism opportunities, employment, and trade
It is estimated that forests support the livelihoods of more than 1.6 billion people globally. In addition, well-managed forests can sustain local economies while conserving ecosystems for future generations.
6. Forests Are a Crucial Source of Food and Medicine
Many of the staples and flavors found in daily diets have their origins in forests. From wild fruits and nuts to the native species that gave us coffee, chocolate, and spices, forests are:
- A rich source of nutrition—especially for rural, remote, and Indigenous communities
- A gene bank for crop improvement and the future of food security
- The origin of around 25% of modern pharmaceuticals drawn from forest plants
The loss of forests risks erasing invaluable medicinal knowledge and genetic diversity that could help combat disease and hunger.
7. Forests Cultivate Mental and Physical Well-Being
Contact with forests delivers proven health benefits. Research shows that forests:
- Lower blood pressure, stress hormones, and anxiety through ‘forest bathing’ (shinrin-yoku)
- Improve immune system function
- Offer recreational spaces that foster exercise, relaxation, and social connection
Beyond physical health, forests nurture cultural practices, spiritual life, and a sense of belonging—values often overlooked but deeply important for human flourishing.
8. Forests Provide Protection Against Natural Disasters
Intact forests act as buffers, protecting landscapes and people. Strong, healthy forests:
- Stabilize slopes, reducing vulnerability to landslides and avalanches
- Shield communities from storms and strong winds, especially in coastal regions
- Prevent desertification by maintaining soil structure and moisture
Mangrove forests, for instance, can absorb storm surges—saving lives and property during hurricanes and typhoons.
9. Forests Inspire Knowledge, Culture, and Connection
Forests have shaped human civilization, spirituality, and creativity for millennia. They are:
- Sacred spaces for many cultures and Indigenous peoples
- Sources of folklore, art, and inspiration
- Crucibles of scientific discovery and environmental stewardship
Educational programs and citizen science projects in forests empower people to connect with nature, fostering a stewardship ethic in young and old alike.
10. Forests Are Essential for Combating the Global Biodiversity Crisis
As humans drive unprecedented extinctions, forests represent our best hope for preserving what remains. Effective forest conservation and restoration projects:
- Protect threatened species and habitats
- Promote ecological resilience and adaptation to climate change
- Reconnect fragmented habitats, allowing wildlife to migrate and thrive
The fate of countless plants and animals is tied to the fate of the world’s forests. Human prosperity—and perhaps survival—depends on their conservation.
Frequently Asked Questions About Forests
Q: How much of Earth’s land is covered by forests?
A: Approximately 31% of Earth’s land area is covered by forests, though this varies regionally.
Q: Why are rainforests especially important?
A: Rainforests are home to over half of Earth’s terrestrial species and regulate both regional and global climate systems.
Q: What are non-timber forest products?
A: These include all resources from forests aside from timber, such as fruits, nuts, medicines, resins, latex, and fibers crucial for diets, health, and economies.
Q: How can individuals help protect forests?
A: People can support sustainable products, reduce paper and wood use, advocate for forest conservation, and participate in tree-planting or citizen science initiatives.
Q: What is “forest bathing”?
A: Forest bathing (shinrin-yoku) is the practice of immersing oneself in a forest environment to promote physical and mental well-being by engaging all the senses.
Table: Global Benefits of Forests at a Glance
