Why we need trees

You’ve probably seen a great deal about how much we need sustainable forests, but are you fully aware of why trees are so crucial? A few of the reasons might surprise you, but trees are vital for people and nature every day.

The reasons we need trees:


The natural balance of life on earth can only be maintained with the important role that trees play. Trees remove excess carbon dioxide from the environment, turning it into oxygen through a process called photosynthesis. Because all animals and humans on land, and even some in the sea, need oxygen to breathe – trees are an essential requirement for life. For help with trees on your property, contact a Tree Surgeon Chelmsford at a site like Benchmark, a leading Tree Surgeon Chelmsford.

To fight climate change

The effects of global warming are linked heavily to rising levels of carbon dioxide in the atmosphere, contributing to the ‘greenhouse effect’. CO2 traps heat from the sun, warming the Earth. Certain natural cycles have always occurred in our planet, but scientific evidence shows that increased levels of CO2 from human activities have the greatest influence on the temperature. As trees absorb carbon dioxide from the atmosphere, the more trees the better for our planet.

To provide wildlife food and shelter

Many British wildlife depend on trees for their survival, providing a much-needed habitat. Birds need trees for their nests, small mammals use stems and roots while bats make their home in the trunk.

To stop flooding

Trees act as a vital flood defence, especially when located close to rivers, streams and rivers. They can help to absorb large amounts of rainwater flowing into different water and flooding.
