Healthy Community

Carbon Sequestration

Carbon dioxide (CO2) is a prominent greenhouse gas that absorbs thermal energy and rereleases it back, trapping it within Earth's atmosphere. A tree is great at absorbing the CO2 from the atmosphere and storing it
as biomass, lowering the temperature.

Filtering Air Pollutants

Chemicals like Ozone (O3), sulfuric dioxide (SO2), and nitrogen oxide (NO2) are harmful when inhaled, especially to individuals with asthma or other respiratory diseases. Clean air is necessary for a healthy community.

Saving Water

Trees absorb underground water from the soil and release it back into the atmosphere. This process allows the soil to reabsorb new rainwater, creating less undrinkable runoffs.

Natural Shade

The urban heat island effect is where buildings and pavement have poor albedo causing heat to be absorbed and linger. Trees can provide natural shading and have a better albedo rate to reflect more sunlight instead of being absorbed. A 40% tree canopy will provide the maximum cooling effect that urban areas should strive for.

Reducing Stress

Trees are shown to reduce blood pressure, less stress, and improve moods.


100K Trees For Humanity

Urban street trees are as vital as forest trees. They provide direct and indirect benefits to create a green and healthy community.

It Pays Back

On top of the ecosystem benefits that it involves, street trees would become beneficial monetary. A study shows that California's 9 million street trees would generate over 1 billion dollars annually. By spending 1 dollar on maintaining a street tree, an average of $5.82 return in benefits.

Planting Justice

We believe that environmental rights are civil and human rights. At 100K Trees for Humanity, we believe that
we must fight for environmental justice as Black and Indigenous People of Color BIPOC, and for our human rights to clean air and water and to nature, by centering the environment within the intersection of racial justice and social justice. Our indigenous communities best demonstrate this—that we must center nature first if we are to live and maintain a healthy, sustainable planet—
for our own existence is inextricably tied to mother nature’s delicate complexity and web of life.


The BIPOC community is three times more likely to live
in a nature-deprived neighborhood than whites. Trees are important for a healthy mind and body to create a healthy community.

Our Plan

The 100K Trees Urban Greenbelt Initiative, 100K Trees for Humanity will co-develop a tree planting with the Eden Area community stakeholders to create a community-driven workforce development, public health, and tree planting climate initiative. The objective is to plant 100K trees, 1 new tree per capita resident from West Oakland down to Fremont which lacks a tree canopy. 


The map is color-coded to indicate which region is severely lacking in trees. A significant lack of trees is shown near the bay from Oakland to Fremont. The ideal tree canopy percentage is 40%, but it differs depending on the area.

Carbon Entry

Trees absorb and store atmospheric carbon dioxide (CO2) as biomass. The removal of atmospheric CO2, a prominent greenhouse gas (GHG) will lower the temperature in the area. 

Soil Health

Harmful nitrogen oxide (NO2) in the atmosphere is absorbed and filtered by trees. The nitrogen absorbed is reintroduced back into the soil as nutrients. The roots of the tree also help prevent erosion, making the ground much more stable.

Water Cycle

Water released back into the atmosphere through evapotranspiration would form new clouds. Clouds act as a cover for the planet to reflect sunlight with their high albedo. This layer of protection helps prevent increased temperature on the surface.
