why planting a tree could save the world

When people talk about plating a tree to save the environment and the world, they think it’s a metaphor or a joke, but in reality one tree can make a massive difference in today’s society. Planting a tree is such a simple thing to do but it has many long-term benefits and it can make a huge difference towards the environment. Trees have played a critical role in maintaining safe levels of oxygen and carbon dioxide (CO2) in the atmosphere for millions of years.

Trees remove and store CO2 from the atmosphere as they grow. They do this by the process of photosynthesis. They use the energy from sunlight to produce sugar, which cellular respiration converts into Adenosine Triphosphate (ATP), the "fuel" used by all living organisms. Trees play an important role in addressing climate change and assisting our agricultural areas to be more sustainable. They do this by helping to reduce atmospheric CO2 levels. They can also assist in preventing salinity and soil erosion, provide shade, food and habitat to native animals.

Trees also clear our air by absorbing air pollution. And they clean a lot of air. Again, to put this into perspective, the easiest way is to quantify air pollution control in monetized terms. Be prepared for another big number her. In a life time, a single tree provides $62,000 worth of air pollution control.

On a world wide scale, trees help to slow down the effects of global warming by using up carbon dioxide and giving out the oxygen we need to breathe.
On a local neighbourhood level, trees offer shade and shelter, which in turn reduces the amount of energy we need to heat and cool buildings, at the same time they remove the impurities from the air we breathe.
Urban trees are especially important because for many people they provide the only daily contact with the natural world away from all the busy cities.

Many people across the world go around spreading the word about plating trees and this happens everywhere from America to Russia. There are organizations that donate money and the materials to keep this project going. The volunteers are all willing to help the earth and keep the planet functioning better for the future. Our population is growing bigger and bigger everyday and we need to make sure our world can provide for our growing population. Trees are so important to our survival and our everyday living. We need trees. They are the reason of our existence.

So by planting a tree you are contributing to so many benefits for the earth like more oxygen for us to breathe less carbon dioxide that we make because the trees absorb it in and convert it into oxygen, more trees for paper and everyday uses, more trees for making furniture, more trees for making and constructing houses. This is how and why you should plant a tree, it could save your life, actually no. It is saving your life.
