Last week was World Environment Day, the United Nations’ day for encouraging worldwide awareness and action to protect our environment. This year’s theme was Air Pollution and asking the world to come together to beat it. Unarguably, air pollution is a complex matter, but also unarguably, the planting of trees is definitely a step in the right direction for improving the quality of the air that we all breathe.

The relationship between trees and air pollution is a complicated one, but with half a football field of forest destroyed every second, we need to understand the impact the loss of trees will have on the quality of our air, and how planting trees will benefit all of us.

Trying to keep this as simple as possible, heat from the earth is trapped in the atmosphere due to high levels of carbon dioxide (CO2) and other heat-trapping gases that prohibit it from releasing the heat into space. This creates a phenomenon known today as the “greenhouse effect.” Trees help by removing CO2 from the atmosphere during photosynthesis to form carbohydrates that are used in plant structure/function and return oxygen back into the atmosphere as a byproduct. Roughly half of the greenhouse effect is caused by CO2. Therefore, trees act as carbon sinks, alleviating the greenhouse effect.Trees in a Forest

In urban areas, trees also reduce the greenhouse effect by shading houses and office buildings. This reduces the need for air conditioning by up to 30 percent which in turn reduces the amount of fossil fuels burned to produce electricity. The combination of CO2 removal from the atmosphere, carbon storage in wood and the cooling effect makes trees extremely efficient tools in fighting the greenhouse effect and thus, air pollution.

Trees also remove gaseous air pollution by uptake via leaf stomata or simply, the leaf pores.  Trees absorb odors and pollutant gases (nitrogen oxides, ammonia, sulfur dioxide and ozone) and intercept airborne particulates (major health hazards in air pollution) out of the air by trapping them on their leaves and bark. Trees along urban roadways can reduce the presence of fine particulate matter in the atmosphere within a few hundred yards of the roadside verge. All of this scientific jargon basically means that trees reduce the concentration of bad stuff in the air that we breathe

Planting trees remains one of the most cost-effective means of drawing excess CO2 from the atmosphere. If every American family planted one tree, the amount of CO2 in the atmosphere would be reduced by one billion pounds annually. This equates to almost 5 percent of the amount that human activity pumps into the atmosphere each year.

Taken together, there is no doubt that trees provide a net positive benefit to the environment, which is why it is almost uniformly true that neighborhoods with lots of trees command greater housing values than Runner in a tree lined urban parkwaythose without. You can help by planting memorial gift trees and gift trees celebrating milestone events for people or pets. The Gifted Tree makes it easy to do, and with our innovative and amazing presentation certificates, it will show you care, as well as make a difference.  Plant your gift tree to help forests devastated by fire or climate change, and improve the quality of the air we breathe!

One question we receive frequently at The Gifted Tree concerns the role trees play in the keeping our water supply safe and clean. When one thinks of forests and majestic trees, a lot of us understand the vital role trees play in helping clean the air we breathe by acting as filters and removing harmful particles and pollutants.  Those same people are less familiar with the role trees play in purifying our water sources, including those that provide drinking water for millions of Americans every day.

Water is probably the most vital resource for our survival. Whether it be for drinking water or washing our clothes, the average American uses an estimated 80-100 gallons of water per day. For many of us, having access to clean drinking water and running water in our homes is a necessity that we often take for granted.

People are not the only ones who count on water for survival. Trees and animals also need water for their existence. Water availability has a direct impact on the health of forests and their inhabitants. Trees are made up of more than 50 percent water and need a steady source of it in order to grow and stay healthy. A single mature oak can consume over 40,000 gallons of water in a year!

Trees improve water quality by slowing rain as it falls to the Earth, and helping it soak into the soil. Trees then serve as natural sponges, collecting and filtering rainfall and releasing it slowly into streams and rivers. Tress are the most effective land cover for maintenance of water quality. They prevent soil from eroding into our waterways which contribute to poor water quality, reduce storm water runoff, and lessen flood damage. Furthermore, the movement of water from the ground, through trees and leaves and back to the environment, allows for clouds to form and significant precipitation to fall.

Having a buffer of forestland by streams and riverbanks does more than just filtering the water. Planting and maintaining woody vegetation along streams provide a wealth of benefits, including filtering sediment, removing nitrogen and phosphorous leaching from adjacent agricultural land uses, and providing stability to the bank through a wood root system. Forest cover has been directly linked to reducing drinking water treatment costs and helping to recharge the water table by allowing water to enter the ground, so the more forest in a source water watershed, the lower the cost to treat that water.

Now you know another of the multitude of benefits trees provide. Luckily, one easy way to protect and clean our water supply is to plant trees, and The Gifted Tree can help. We plant gift trees to show you care – memorial trees in remembrance of a lost loved one, human or pet, or gift trees to celebrate a milestone event.  Not only will you be remembered due to the unique and innovative presentation tree certificate the recipient will receive, but you are giving the world a gift too – clean water.
