How do trees clean the air and store carbon? | One Tree Planted
Summary
TLDRTrees play a crucial role in cleaning our air and combating climate change. They absorb carbon dioxide and release oxygen through photosynthesis, acting as natural air filters. Trees also intercept pollutants and reduce air pollution, which can cause respiratory illnesses. By storing carbon in their biomass and the surrounding soil, forests help mitigate climate change. Deforestation disrupts this cycle, but sustainable forest management, protection, and tree planting can enhance carbon sequestration and improve air quality.

Q & A
How do trees help clean the air?
-Trees clean the air by absorbing carbon dioxide through their stomata during photosynthesis and releasing oxygen. They also intercept particulate matter and absorb gaseous pollutants like carbon monoxide, sulfur dioxide, and ground-level ozone.
What is the role of trees in creating habitats for wildlife?
-Trees provide essential habitats for various forms of wildlife by offering shelter, nesting sites, and food sources, which are crucial for maintaining biodiversity.
How do trees contribute to improving community health and well-being?
-Trees improve community health and well-being by reducing air pollution, which can lead to respiratory illnesses. They also provide shade and release water vapor, helping to cool the air and save lives during heatwaves.
What is the process by which trees absorb carbon dioxide?
-Trees absorb carbon dioxide through pores on their leaves called stomata. During photosynthesis, they convert this carbon dioxide and water into oxygen and glucose, releasing oxygen back into the atmosphere.
How much carbon does America's forests sequester annually?
-America's forests sequester approximately 860 million tons of carbon each year, which is about 16% of the US annual emissions.
What percentage of carbon taken up by trees is stored in the forest ecosystem?
-About 48% of the carbon taken up by trees is stored in the forest ecosystem, including the leaf litter and soil.
How do trees help mitigate climate change?
-Trees help mitigate climate change by removing carbon dioxide from the air during photosynthesis and storing this carbon in their biomass, as well as in the forest's leaf litter and soil.
What is the potential increase in carbon sequestration through natural forest management?
-There is a potential to increase carbon sequestration by an additional 23% through natural forest management practices.
What actions can be taken to support the role of trees in climate change mitigation?
-To support trees' role in climate change mitigation, one can practice sustainable management, protect forests, and plant trees, which can slow the rise in temperature.
How do trees cool the air during heatwaves?
-Trees cool the air during heatwaves by creating shade and releasing water vapor through a process known as transpiration.
What is the significance of trees in the context of the global carbon cycle?
-Trees are significant in the global carbon cycle as they act as long-term carbon storage systems, removing carbon dioxide from the atmosphere and storing it in their biomass and the surrounding ecosystem.
Outlines
🌳 Trees: Guardians of Air and Carbon
This paragraph explains the multifaceted benefits of trees to the environment and human health. Trees create habitats, filter water, improve community health, clean the air, and sequester carbon. They act as the 'lungs of the world,' producing oxygen through photosynthesis by absorbing carbon dioxide and releasing it back after converting it into glucose. Trees also remove pollutants from the air, intercepting particulate matter and absorbing harmful gases like carbon monoxide and sulfur dioxide. They mitigate climate change by storing carbon in their biomass and the surrounding soil, with America's forests sequestering about 860 million tons annually. Deforestation and fires, however, disrupt this cycle, releasing stored carbon back into the atmosphere.

take a deep breath
some of that air you just inhaled has
been cleaned by trees trees help the
world in many ways they create habitats
for wildlife filter water improve
community health and well-being clean
the air and sequester carbon
[Music]
let's dive into how trees improve our
air and store carbon trees are like the
lungs of the world as they create a lot
of the oxygen we breathe trees absorb
carbon dioxide through pores on their
leaves called stomata and take in water
through their roots during
photosynthesis the tree's cells convert
that carbon dioxide and water into
oxygen and glucose which is a type of
sugar then oxygen is released back into
the atmosphere through the stomata and
the glucose gives the tree energy to
grow not only do trees provide us with
oxygen to breathe they also remove
pollutants from the air air pollution
comes from many sources such as burning
fossil fuels manufacturing and forest
fires it comes in different forms such
as particulate matter which can be
intercepted by the tree's bark branches
and leaves there are also gaseous
glutens like carbon monoxide sulfur
dioxide and ground level ozone that are
absorbed through the stomata on the
leaves surfaces air pollution is a major
problem around the world and can lead to
significant human and ecosystem health
issues healthy trees reduce air
pollution and are able to help prevent
respiratory illnesses caused by
pollutants
trees also cool the air by creating
shade and releasing water vapor which
can help to save lives during heat waves
especially in densely populated areas
with lots of pavement
trees provide many essential services to
humans but because they store carbon
they also serve the planet by helping to
mitigate climate change trees remove
carbon dioxide from the air during
photosynthesis and store this carbon in
their roots leaves trunks and branches
as the trees grow larger they store more
and more carbon making them an excellent
long-term carbon storage system
america's forests sequester about 860
million tons of carbon a year which is
roughly 16 of the us annual emissions
carbon is stored not only in the biomass
of the trees themselves but the leaf
litter and soil of the forests hold 48
percent of carbon taken up by trees
meaning that a healthy forest ecosystem
stores far more carbon than just the
trees alone
however deforestation and human-caused
fires disrupt the cycle of carbon
storage and can be major sources of
carbon being released back into the
atmosphere
forests currently absorb about 30
percent of carbon emissions but there is
potential to add another 23 through
natural forest
to mitigate climate change and help
clean the air there are a few things we
can do by practicing sustainable
management protecting forests and
planting trees we can slow the rise in
temperature
but we can't do it
alone one tree planted is committed to
growing resilient healthy productive
forests for the benefit of people
communities and the planet if you would
