The responsibility of young saplings and young trees is to grow until they have reached their height and become fruitful, useful individuals. The older more mature trees overhead will provide shelter from the elements, clean the air of contaminants and provide nutrients in the form of decomposing foliage.
A mature tree removes almost 70 times more pollution than a newly planted tree. They are just equipped to do it. Mature trees are like the lungs of the planet, without them, we would not exist.They breathe in carbon dioxide and breathe out oxygen.
Roughly 800 million tons of carbon are found in the trees in the US alone, which contributes savings of $22billion in control costs and mature trees release enough oxygen to sustain 2 human beings!
The definition of Maturity - To get to "full development" and having reached a desired or final condition.
I think one of the most important lessons to learn in life is that life is a journey. Its a process, with steps that need to be taken to ensure that we become the individuals who are useful and functioning fully in their purpose. Young trees are just NOT equipped to function in a capacity close to their mature counterparts, but by staying close by and allowing time to take its course, they will reap all the benefits provided by the older more mature trees.
1 Corinthians 13:11 - When I was a child, I talked like a child, I thought like a child, I reasoned like a child. When I became a man, I put childish ways behind me.
Be teachable. Find mature men and women who you can look up to and allow them to become "mentors" in your life through watching what they do, and hearing what they say. Learning the lessons that they have learnt along the way will help prevent you reinventing the wheel!!
