LIFE SCIENCE
We have physics, chemistry and several other fields of science to explain objects and forces existing around us. But what is that area where we must deal with ourselves and other living beings. Let us assume what kind of field of science this is.Yes, it is what we call life science. Life science is the study of living beings. It deals with any type of life form whether it is acellular or cellular. The age of the earth is 4.5 million years. But life evolved on earth around 3.8 million years ago. Then life underwent crucial change. Animals of different varieties are grouped in broad regional units. Each unit shows faunal similarities but also contains endemic beings (animals that are found only in that particular region). For example, Australia is rich in marsupials. The earth has various types of life forms according to geographical characteristics and climate. For instance, a mountain has different living beings in comparison to a desert. Such factors are appreciable in the case of desert life and marine life. The desert having warm and sandy climate bears such types of creatures which can adapt to it. Deserts cover about one-fifth of the earth's surface. Influenced by bizarre climate, a desert plants develop tough skins and have reduced foliage to prevent evaporation and to withstand scorching heat. Camels can endure in deserts without having water for several days. Gazelles, Rainbow Lizard, Chameleon, Vulture, Horned viper, Locust and many other creatures exist in the desert. Various types of plants also exist here, enduring its harsh climate, such as palm tree, cactus, etc. Underwater variety of life is also very significant.Starting from sessile sponge, underwater life-science is blessed with killer fishes like the piranha, helping hands like dolphins, giants like whales, hunters like sharks and so on. At the end one thing must be remembered that life science is not a science to be studied only. It is to be researched and experienced. WAR
As the novel “All Quiet on the Western Front” by Erich Maria Remarque reminds us people don't kill other people, they kill their ideology. Most people are manipulated by their leaders. Apart from that, war has often occurred over sovereignty, territory, resources, religious ideology, even for love or the one who is loved. From west to east several civilizations evolved which were involved in great wars like the Kalinga war (between the Maurya empire under Ashoka and state of Kalinga), battle of Thermopylae (between Persian empire of Xerxes 1 and Spartan king Leonidas 1), invasion of Alexander the Great, Punic wars between Carthaginians and Romans, Peloponnesian wars (sometimes it is considered as the first true world war, which was fought among the Greek city states). Then in the Middle Ages several great wars took place, like the Crusades, Mongol invasions, Napoleonic wars like the Battle of Waterloo (1815), American independent war (1776-1783), Indo-China opium war (1839-1842). We have witnessed the horror of two world wars between 1914 and 1945. They were the most destructive and blood spilling wars ever in human history. We came across more wars, like the Arab-Israeli wars from 1948 to 1973, Korean war (1950-1953), Vietnam war, Liberation War of Bangladesh, Iran-Iraq war; and now, in the name of war against terror, Americans are fighting the Afghan Taliban forces in Afghanistan (from 2001 onwards) and have also fought against Iraq and occupied it. Around the world nowadays the number of ongoing major military conflicts is about eight, including the Afghan civil war, Iraq war, war in north-west Pakistan. Besides, other major conflicts are the Somali civil war, Mexican drug war and Sudanese nomadic conflicts. Other smaller scale armed conflicts are the Korean conflict, Arab-Israel conflict, and insurgency in Jammu and Kashmir, Kurdistan conflict, insurgency in Chechnya and many insurgencies in the African continent.
