Trees are important because they provide oxygen, improve air quality, support biodiversity, help combat climate change, protect against floods, reduce soil erosion, and enhance human health and well-being.

Air and Water Purification

Trees absorb harmful gases like carbon dioxide, nitrogen dioxide, and carbon monoxide, and release oxygen through photosynthesis. Their roots filter pollutants from stormwater, which leads to cleaner rivers and lakes.

Climate Change and Cooling

Trees help slow climate change by storing carbon and cooling the environment, especially in urban areas—urban trees can reduce city temperatures by up to 10 degrees.

Soil Protection and Flood Prevention

Tree roots stabilize soil, preventing soil erosion and reducing the impact of floods by absorbing excessive rainfall.

Biodiversity and Habitat

Nearly half of Earth's terrestrial species rely on forests for habitat, making trees vital to biodiversity. Trees provide shelter and food for insects, birds, mammals, and other wildlife.

Human Health and Well-being

Spending time near trees helps relieve stress, lower blood pressure, and strengthen immunity. Green spaces with trees contribute to better physical and mental health in communities.

Economic and Material Benefits

Trees supply materials like wood and medicines, offer food such as fruits and nuts, and provide shade which reduces the need for energy-consuming cooling systems.

In summary, trees are vital to life on Earth due to their environmental, economic, health, and social contributions.
