Planting trees is one of the easiest and most sustainable ways to positively affect the environment. We need trees now more than ever! Communities across the state have been devastated with the loss of tens of millions of ash trees since the emerald ash borer was first discovered in metro Detroit in 2002. Trees are our lifeline to cleaner air and a healthier environment.Here’s how trees make a difference:Trees improve air quality by producing oxygen. They also store carbon, offsetting harmful byproducts of fossil-fuel burning.They moderate the effects of sun and wind, and they clean the air by trapping dust, pollen and other pollutants.Planted in the right places around buildings, trees can significantly reduce air-conditioning costs. This means less Freon, an inflammable and odorless chemical emitted from air conditioners. It is considered to have damaging effects to the ozone layer.Trees increase property value.Trees generate jobs and contribute raw materials for buildings, newspapers, books, etc. They are renewable, biodegradable and recyclable.They provide shelter and food for wildlife such as birds, squirrels and bugs.Trees make people feel good. Workers are more productive when they see trees along their commute routes and from their office windows.Landscapes that include trees help relax us, lower heart rates and reduce stress.
