Trees and climate

They help mitigate the greenhouse effect, absorbing carbon dioxide — and therefore climate-altering emissions of anthropogenic origin — throughout their lifetime.

Trees produce oxygen

Through cellular respiration, trees trap CO2 and release oxygen into the atmosphere. The CO2 is converted into organic matter, which in turn becomes fertile soil. A tree produces on average 20–30 litres of oxygen per day, while each person requires on average 300 litres of oxygen per day.

Trees clean the air

They are able to filter particulate matter and pollutants present in the air; their leaves intercept harmful substances such as sulphur dioxide and nitrogen dioxide.

Trees clean the water

They reduce rainfall runoff, replenishing groundwater and preventing pollutants from reaching the sea.

Trees prevent soil erosion

Their roots penetrate the ground — particularly on mountain and hillside slopes — holding the soil together and preventing it from sliding away.

Trees beautify gardens, parks and cities

And they are good for physical and mental wellbeing. It is proven that greenery relaxes, refreshes and uplifts.

Trees regulate temperature

They provide shade and absorb sunlight, cooling the summer heat. In winter, they can soften the coldest winds.

Trees produce wood

Until just a few years ago, wood from various species accompanied virtually every human activity — from industry to transport, from construction to leisure, from heating to mechanics.

Trees increase biodiversity

They provide shelter for dozens of animal species — birds, insects, rodents. Entire ecosystems are built around their ecology.

Trees help children grow up healthy

Children need trees to climb so as not to lose their wild side and their connection with the natural world. Discovering nature nurtures children's motor skills, cognitive and intellectual development, and imagination. It has been found that children who play in contact with trees and grass behave more creatively.

Trees are a historical memory

The oldest trees are hundreds if not thousands of years old, and carry within their trunks the marks of time — temperatures, droughts, quantities of nutrients. From a trunk, the past can be understood.

Trees are our historical memory

Once a tree is planted, in all likelihood it will outlive us and our children. A genuine legacy for the entire community.
