The universe is a beautiful creation of God governed by four seasons winter, summer, autumn and spring, the Sun to light the day and the moon to illumine the night all through these seasons. Rotation of earth around its axis makes a day comprising of a day and a night. While the revolution of earth around the sun makes one complete year comprising of four seasons- winter, spring, summer and autumn, with the Sun to light the day and the moon to illuminate the night all through these seasons.
It is cold and dry during the winter and the hour of day is short and the night is long. If we look at the mountains and hills it is all dry and dusty and when we glance at these fields, we find dried leaves and grasses. We call it a dry season because almost all the grasses die out and the leaves fall down. Adding to it, it looks more deserted with the traditional method of cutting and collecting firewood during this time of the year for the storage for the whole year. It is a matter of concern today to preserve and protect the mother earth in which we live.
It takes approximately twenty years for the red oak tree to attain 5 inch diameter. The age is being calculated using “diameter x growth Factor = approximate tree age”. Trees have different growth rates, depending on their species. That means if we are going to collect small mini truck full firewood for cooking for a small family then we are going to cut down almost ten trees which may be of twenty years old. It is a fact that we all experience in our day to living especially in rural areas as there are very less alternative energy sources for cooking. This tradition is going to desert the hills in the near future if new saplings are not replaced to the fallen ones. If we didn’t take precautions then it is sure the coming generation will complain about the heat, wind, rain, humidity and temperature. It is a tragedy we are bringing it upon ourselves and our future. This is clarion call for each of us to take the initiative and go green. It appears to me that our mother earth is mourning for her lost beauty and bounty.
Time and seasons change, spring comes to welcome the beauty of the nature with its pleasant weather. The hour of the day and the night is same and the length of the day will increase everyday till summer. It is welcomed by the beautiful pink blossom of the wild cherry and the beautiful white blossom of the prunes. The trees show its most beautiful stage of the year, aching by the flowers without its leaves in the hills around if we are near to nature. Summer brings the warmest season with wet weather and rich vegetation. We can see our nature; dressed in her lovely and beautiful green, giving all the requirements to every being according to the needs. There is everything for everyone’s needs provided by the nature but not to everyone’s greed. The days are longer and the nights are short during summer. Autumn shows the shedding of leaves from deciduous trees as they pave way for further growth. It is also known as fall in the US and Canada. The hour of day and the night is almost same like spring in which the day length will decrease everyday till winter. It marks the transition from summer into winter, and the chill of winter is on the horizon. This season is a time of bounteous fruits where most food items and grains are harvested during the autumn which includes pumpkins and apples and other vegetables.
Transition of day to night is the beautiful gift of nature to all the beings living in this universe. Day and night is given in order to perform the vital activities of life. Sun lights up the day and Moon reflect the sun in the night. According to activities of the organisms during the light and dark, organisms are divided into three types.
Those that are active during the night are called “nocturnal”. Their activities peak during the dark. Many of these animals having a specially developed sense of vision which help them to see in the dark, and they often have excellent hearing as well. They come out at night and sleep or rest during the day. There are a number of reasons for an animal to be nocturnal; many desert animals are active at night because it is cooler, and their rate of water loss is decreased as a result. Owls, bats and wolves are well-known nocturnal creature. If we see the owl at noon it is a cause of concern since it is usually seen at night.
There are also animals which are active during the twilight. It is called as “crepuscular’. Their behaviour is very different from the diurnal and the nocturnal animals which are active during the dawn or only in the dusk, respectively.The distinction is not however absolute, because crepuscular animals may also be active on a bright moonlit night or on a dull day. The animals use this time to feed, drink and engage in other behaviour as their predators are inactive during the twilight. Deer, many moths, rabbits, housecats, rats, are crepuscular. Humans also have a tendency to encourage diurnal behavior among the animals they interact with; dogs which are naturally crepuscular, learn to become diurnal through human interactions.
Organisms that are active during the day are “diurnal” also term as “cathemeral”. They are active during the daylight. Like “crepuscular” and “nocturnal” animals, the daily patterns of diurnal animals are established through circadian rhythms, patterns built into their body chemistry. Being active during the day certainly has some advantages, especially for creature with poor visibility like us humans.
We are the most beautiful creation of God. With the dawn we can hear the birds chirping in the air, searching for its food, feeding and enjoying the first ray of sunlight. But we, humans with modernization most of us fail to see the beautiful sunrise for so many reasons. Why? We claim ourselves to be the ruler of all the beings on this earth, but we are missing the beauty of the nature day by day. With the industrialization, people are becoming nocturnal and engaged to the night shift duty which is not accepted by our body system. We are running so much to changing time that sometimes we forgot that we are diurnal too. Most of the students study at night; most of our youth enjoy night life with their friends in various ways not knowing the consequences. The disruption of our established biological rhythms can be harmful. We are not adapted to being active at night, which means that we are vulnerable to alertness, stress, frustration, or pressured into unusual behavior and may led to certain diseases like obesity, which is very common or may become sick to physical and psychological complications. Day length plays an important role in almost all the organisms with the exception of those which exist in the deep oceans. It is important for us to know, to understand and to have this knowledge about what type of organism we are in this universe and to do the activities that are permitted by nature for us to maintain a healthy mind, body and relationship with our nature. We are created by God to keep this universe clean and green.
