How does planting trees help the earth

The research is based on the measurement of the tree cover by hundreds of people in 80, high-resolution satellite images from Google Earth.

Artificial intelligence computing then combined this data with 10 key soil, topography and climate factors to create a global map of where trees could grow. This showed that about two-thirds of all land — 8. Of the 3. In fact many studies suggest sheep and cattle do better if there are a few trees in the field.

However, some scientists said the estimated amount of carbon that mass tree planting could suck from the air was too high.

Prof Simon Lewis, at University College London, said the carbon already in the land before tree planting was not accounted for and that it takes hundreds of years to achieve maximum storage.

He pointed to a scenario from the Intergovernmental Panel on Climate Change 1. Other scientists said avoiding monoculture plantation forests and respecting local and indigenous people were crucial to ensuring reforestation succeeds in cutting carbon and boosting wildlife. Climate change. Tree planting is one of the simplest and most effective ways of tackling climate change caused by greenhouse gas. This story was originally published on the 1st of September Trees absorb odors and pollutant gases nitrogen oxides, ammonia, sulfur dioxide and ozone and filter particulates out of the air by trapping them on their leaves and bark.

In one year an acre of mature trees can provide enough oxygen for 18 people. Three trees placed strategically around a single-family home can cut summer air conditioning needs by up to 50 percent. By reducing the energy demand for cooling our houses, we reduce carbon dioxide and other pollution emissions from power plants.

Shade from trees slows water evaporation from thirsty lawns. Most newly planted trees need only fifteen gallons of water a week. As trees transpire, they increase atmospheric moisture.

Trees reduce runoff by breaking rainfall thus allowing the water to flow down the trunk and into the earth below the tree.

This prevents stormwater from carrying pollutants to the ocean. When mulched, trees act like a sponge that filters this water naturally and uses it to recharge groundwater supplies.

On hillsides or stream slopes, trees slow runoff and hold soil in place. Food-producing trees provide fruit, nuts, berries, and leaves for consumption by both humans and animals, and pack a powerful nutritional punch.

Did you know that hospital patients with rooms overlooking trees recover faster than those without the same view?

Trees help reduce stress and anxiety, and allow us to reconnect with nature. In addition, shade provided by tree coverage helps protect our skin from the ever-increasing harshness of the sun. Trees help cool the planet by sucking in and storing harmful greenhouse gases like carbon dioxide into their trunks, branches, and leaves — and releasing oxygen back into the atmosphere. Fortunately, a mature tree can absorb an average of 22lbs of carbon dioxide per year , making cities a healthier, safer place to live.
