Each and every process that occurs in leaves can be described as an individual miracle.
The services that plants carry out for other living things are not restricted to giving off oxygen and water. Leaves at the same time carry out the most highly developed cleansing and purification functions. The cleaning tools we regularly use in our daily lives are produced and set in operation as the result of long studies by experts and after the expenditure of a lot of effort and money. These need considerable technical support and maintenance both during and after use. In addition, problems or defects that can arise on a daily basis, and the necessary staff and the need for other tools and renewals where necessary, can all mean a great many more processes.
There are hundreds of details to consider even in a small piece of cleaning equipment, whereas plants do the same job as these tools in return for just sunlight and water, and perform the same cleaning service with the guarantee of greater efficiency. They also give rise to no waste product problem, because the waste product they give off after cleaning the air is oxygen, which all living creatures need!
Leaves Catch Air Pollutants
Tree leaves possess tiny filters that catch pollutants in the air. There are thousands of tiny hairs and pores, invisible to the naked eye, on the surface of a leaf. The individual pores trap pollutants in the air and send them to other parts of the plant to be absorbed. When it rains, these substances are washed to the ground. These structures on the surfaces of leaves are only of the thickness of a film; but when one considers that there are millions of leaves in the world, it becomes clear that the amount of pollutants trapped by leaves is not to be underestimated. A 100-year-old beech tree, for example, has about 500,000 leaves. The amount of pollutants caught by these leaves is more than one might guess. About a thousand square metres of plane trees can trap 3.5 tons, and pine trees 2.5 tons of pollutants! These materials then fall to the ground with the first rain. The air in a forest two kilometers from a settlement area is 70 percent cleaner than that in the settlement area. Even in winter when trees lose their leaves, they still filter out 60 percent of the dust in the air.
Trees can trap dust weighing 5 to 10 times more than their leaves: bacteria levels in an area with trees is considerably less than in one with no trees.
As a food resource and cleaning tool, scientists showed that leaves are protected by another perfectly planned mechanism. With the approach of winter the air grows colder and the days shorter, and less light reaches the Earth from the Sun. This reduction causes changes in plants, and the aging process in leaves, or leaf fall begins.
Before trees lose their leaves, they begin to absorb all the nourishing substances in the leaves. Their aim is to prevent substances such as potassium, phosphate, and nitrate from disappearing with the falling leaves. These substances are directed through the pipelines that run through the layers of bark and the centre of the trunk. The collection of these substances in the xylem makes it easier for them to be digested by the tree.
Each and every process that occurs in leaves can be described as an individual miracle. These systems in green leaves, in the superb planning as in a microscopic factory, are proof of the creation of God, the Lord of all the worlds, and have come down to our day after hundreds of thousands of years in the same perfect state with no changes and no defects.
