Phytoplankton are the main reason the ocean is one of the biggest carbon sinks. These microscopic marine algae and bacteria play a huge role in the world's carbon cycle – absorbing about as much carbon as all the plants and trees on land combined.
How Much CO2 Do We Exhale Per Day The average person exhales approximately 2.3 pounds of CO2 per day. The exact quantity varies depending on your activity level. The more engaged you are in vigorous-intensity activity, the more CO2 you produce.
The ocean stores 50 times more carbon than the atmosphere, and 20 times more than land plants and soil combined, Buesseler said.
(0.04%) 421 ppm
The current global average concentration of CO2 in the atmosphere is (0.04%) 421 ppm as of May 2022. This is an increase of 50% since the start of the Industrial Revolution, up from 280 ppm during the 10,000 years prior to the mid-18th century.
Douglas-Fir, True Fir, Beech, Spruce and Maple are among the ones that produce the most oxygen. Aspen and Oak are halfway for oxygen production. Pine trees are generally releasing less oxygen because they have smaller leaves.
Best Carbon Capture Plants
Bamboo has been around for millennia, and while it is often blamed for deforestation, bamboo is able to absorb 5 times more GHG emissions and produce around 35% more oxygen than its equivalent in trees. One hectare of bamboo can absorb around 60 tons of carbon dioxide every year.
CO2 is expelled upon exhalation and the cycle begins anew. Humans do not absorb all of the inhaled O2 for metabolism; inhaled air contains 21% O2 while exhaled breath contains approximately 16% O2 and 5% CO2.
The American Conference of Governmental Industrial Hygienists (ACGIH) recommends an 8- hour TWA Threshold Limit Value (TLV) of 5,000 ppm and a Ceiling exposure limit (not to be exceeded) of 30,000 ppm for a 10-minute period. A value of 40,000 is considered immediately dangerous to life and health (IDLH value).
Ocean habitats such as seagrasses and mangroves, along with their associated food webs, can sequester carbon dioxide from the atmosphere at rates up to four times higher than terrestrial forests can. Their ability to capture and store carbon make mangroves highly valuable in the fight against climate change.
Globally, the two most important carbon sinks are vegetation and the ocean. Soil is an important carbon storage medium. Much of the organic carbon retained in the soil of agricultural areas has been depleted due to intensive farming.
The fraction of the beneficial molecule CO2 in the current atmosphere is tiny, about 0.04% by volume. This level is about 30% larger than pre-industrial levels in 1800. But today's levels are still much smaller than the levels, 0.20% or more, that prevailed over much of geological history.
According to education site Vision Learning Earth's atmosphere is composed of approximately 78 percent nitrogen, 21 percent oxygen, 0.93 percent Argon, 0.04 percent carbon dioxide as well as trace amounts of neon, helium, methane, krypton, ozone and hydrogen, as well as water vapor.
The live oak is the most efficient carbon capturing tree, it being able to sequester some 10,994 CO2 equivalent over its lifetime. Ranking second is the East Palatka holly, with a lifelong carbon fixation of 7,321 CO2 equivalent.
Broadleaved species – such as oak, beech and maple – are best because they have a larger surface area of leaves which generates more photosynthesis, whereas conifers absorb more heat.
In case of giant tropical bamboo, one newly planted bamboo plant can sequester 2 tons of carbon dioxide in just 7 years. In comparison, a typical hardwood tree will sequester 1 ton of carbon dioxide in 40 years. When compared to pine, bamboo can absorb up to 5 times more CO2.
Pulmonary effects can present as early as within 24 hours of breathing pure oxygen. Symptoms include pleuritic chest pain, substernal heaviness, coughing, and dyspnea secondary to tracheobronchitis and absorptive atelectasis which can lead to pulmonary edema.
In hospital settings, 100% oxygen may be delivered — but even then only on a short-term basis, says Boyer — less than 24 hours and preferably less than 12 hours. To breathe pure oxygen at that level for any longer can have toxic results, including "shock lung," or adult respiratory distress syndrome.
Consider that humans breathe out most of the O2 they inhale; at the surface they breathe in 21% and exhale 16% O2 and 5% CO2.
The amount of inhaled air contains 21% of oxygen and 0.04% of carbon dioxide, while the air we breathe out contains 16.4% of oxygen and 4.4% of carbon dioxide. This is because our cells use oxygen from the inhaled air to release energy and give out carbon dioxide as a byproduct.
Bamboo: THE solution against greenhouse gases
Indeed, thee bamboo absorbs 5 times more greenhouse gases and produces 35% more oxygen than an equivalent volume of trees! It has a very important CO2 retention capacity since one hectare of bamboo grove can capture up to 60 tons of CO2 each year.
Algae replicates the same process but “absorbs” the carbon in the form of more algae. Algae can consume more carbon dioxide than trees because it can cover more surface area, grow faster, and be more easily controlled by bioreactors, given its relative size.
The five major sinks are: fossil fuels and carbonate rocks; forests; soils, including non-woody plants; the oceans and. the atmosphere.

The air in Earth's atmosphere is made up of approximately 78 percent nitrogen and 21 percent oxygen. Air also has small amounts of other gases, too, such as carbon dioxide, neon, and hydrogen.
The gaseous area surrounding the planet is divided into several concentric strata or layers. About 99% of the total atmospheric mass is concentrated in the first 20 miles (32 km) above Earth's surface.
