When we breathe out, the carbon dioxide that is produced is released into the air. Plants such as trees, on the other hand, can take in this carbon dioxide, which is unusable for humans, and use it to produce their own energy. Through photosynthesis, humans can again breathe in the oxygen that was produced and survive.
“Trees remove carbon dioxide from the atmosphere and reduce the greenhouse gas effect, all while providing us with clean air to breathe.”
It's a ludicrous strategy, for not only do pine trees – or any other tree species for that matter – not produce ozone, they actually help reduce pollutants such as carbon dioxide and dust, lower ambient air temperature and produce oxygen, says Dr. Eric Taylor, forestry specialist with Texas Cooperative Extension.
In addition to photosynthesis, trees also go through a process called respiration. Still, there's not nearly as much photosynthesis going on in winter as there is in summer. Trees do most of the work creating oxygen and cleaning the air of gases like carbon dioxide in the spring and summer.
Trees are vital. As the biggest plants on the planet, they give us oxygen, store carbon, stabilise the soil and give life to the world's wildlife. They also provide us with the materials for tools and shelter.
Which trees give off the most oxygen?
- Pines are at the bottom of the list in terms of oxygen release because they have a low Leaf Area Index.
- Oak and aspen are intermediate in terms of oxygen release.
- Douglas-fir, spruce, true fir, beech, and maple are toward the top of the list for oxygen release.

"A mature leafy tree produces as much oxygen in a season as 10 people inhale in a year." "A 100-foot tree, 18 inches diameter at its base, produces 6,000 pounds of oxygen." "On average, one tree produces nearly 260 pounds of oxygen each year. Two mature trees can provide enough oxygen for a family of four."
Given that plants do not have pain receptors, nerves, or a brain, they do not feel pain as we members of the animal kingdom understand it.
Trees produce Oxygen during night and absorb Carbon Dioxide, the prime minister said while addressing a program on the importance of planting trees.
Ficus plant have a tree-like structure and is grown commonly in many offices and houses. Ficus plant give oxygen at night and prefer shady and medium-light over direct sunlight and heat. They are not among the hard to grow plants and carries long life span.
FILTHY AIR: Without trees, humans would not be able survive because the air would be unsuitable for breathing. If anything, people would have to develop gas masks that filter the little oxygen that would be left in the air. Anyway, trees take carbon from the atmosphere through photosynthesis in order to make energy.
When we take a breath, we pull air into our lungs that contains mostly nitrogen and oxygen. When we exhale, we breathe out mostly carbon dioxide.
Through a process called photosynthesis, leaves pull in carbon dioxide and water and use the energy of the sun to convert this into chemical compounds such as sugars that feed the tree. But as a by-product of that chemical reaction oxygen is produced and released by the tree.
Like all plants, grass plants in your lawn take in carbon dioxide from the air. Then, as part of the process of photosynthesis, those grasses help produce the oxygen you breathe. A 25-square-foot area of healthy lawn grasses produces enough oxygen each day to meet all the oxygen needs of one adult.
A human breathes about 9.5 tons of air in a year, but oxygen only makes up about 23 percent of that air, by mass, and we only extract a little over a third of the oxygen from each breath. That works out to a total of about 740kg of oxygen per year. This is about seven or eight trees' worth.
Trees release oxygen when they use energy from sunlight to make glucose from carbon dioxide and water. Averaged over a 24-hour period, they produce more oxygen than they use up; otherwise there would be no net gain in growth.
And the least tree-filled countries? There are five places with no forest whatsoever, according to World Bank's definition* - Nauru, San Marino, Qatar, Greenland and Gibraltar - while in a further 12 places there is less than one per cent.
Air pollution can directly contaminate the surface of bodies of water and soil. This can kill crops or reduce their yield. It can kill young trees and other plants. Sulfur dioxide and nitrogen oxide particles in the air, can create acid rain when they mix with water and oxygen in the atmosphere.
Trees can live anywhere from less than 100 years up to more than a few thousand years. It all depends on what type of tree it is. In the United States, the tree with the longest lifespan is the bristle cone pine,which grows in the mountains of Nevada and southern California. A singletree can live up to 5,000 years!
Dracaena plants have shown to be one of the most effective air filters. The plant removes formaldehyde, benzene, trichloroethylene and carbon dioxide – all of which are linked to health problems. Dracaena plants also tend to increase the humidity of a room which in turn helps to control respiratory distresses.
One tree produces nearly 260 pounds of oxygen each year. One acre of trees removes up to 2.6 tons of carbon dioxide each year.
Of the 26 plants, silk oak or silver oak (Grevillea robusta), walnut plant ( Juglans regia), Holly oak (Quercus floribunda), fig (Ficus carica) and red cedar (Toona ciliata) were found to be best performers, the study said.
Trees—all plants, in fact—use the energy of sunlight, and through the process of photosynthesis they take carbon dioxide (CO2) from the air and water from the ground. In addition to the CO2 that trees capture, they also help soil capture significant amounts of carbon.
The Short Answer:Air pollution is caused by solid and liquid particles and certain gases that are suspended in the air. These particles and gases can come from car and truck exhaust, factories, dust, pollen, mold spores, volcanoes and wildfires. The solid and liquid particles suspended in our air are called aerosols.
On Days when High Particle Levels are Expected, Take these Extra Steps to Reduce Pollution:
- Reduce the number of trips you take in your car.
- Reduce or eliminate fireplace and wood stove use.
- Avoid burning leaves, trash, and other materials.
- Avoid using gas-powered lawn and garden equipment.
- Increase Ventilation. Ventilating homes reduces moisture levels, a major problem for indoor air quality.
- Beeswax Candles. Beeswax candles act as natural air purifiers.
- Salt Lamps. A salt lamp is another great natural air purifier.
- Activated Charcoal.
- Houseplants.
- Essential Oils.
The groups most affected by air pollution are people of color, elderly residents, children with uncontrolled asthma, and people living in poverty. Vulnerable populations may experience more health effects because these populations already have higher rates of heart and lung conditions.
Keeping Aloe Vera plant at home is also an expedient way to remove harmful solvents from the air, such as formaldehyde and benzene. Aloe Vera is an air -filtering plant that can sit on a sunny corner of your desk, otherwise forgotten, but will continue to purify the air around you.

Plants have been found to reduce levels of dust through a means that is unknown to scientists. Not only do houseplants reduce dust levels indoors, but they also help to purify the air and stabilize humidity. Many easily cared for houseplants help reduce dust.
Similar to other household succulents, snake plants help to filter indoor air. What's unique about this particular plant is that it's one of the few plants that can convert carbon dioxide (CO2) into oxygen at night. This quality makes it an ideal plant for bedroom decor as it can help regulate healthy airflow.
Plants Help Kill VirusesSchoenberg quotes the NASA study reporting that “Plant roots and their associated microorganisms destroy pathogenic viruses, bacteria, and organic chemicals, eventually converting all of these air pollutants into new plant tissue."
Cacti is the best in reducing radiation and bacteria.Cacti is very strong in eliminating bacteria. In tackling pollution, cacti is also great at reducing radiation. In addition, cacti absorbs carbon dioxide at night to release oxygen.
