The Evolution of Technology - Essay Example In the early 1990’s Internet has revolutionized the world. Communication is being made at the speed of light. E-commerce is the result of the Internet. Instead of outdoor shopping, many people are purchasing goods through the Internet. Human beings are different from another animal, that’s why they are called as social animals. This is because they can think and most importantly can communicate easily with each other. To reduce the gap between geographical areas and the curiousness of man to know what’s on the side has made him invent different things.Thousands of years ago they started communicating with each other. In 3500BC alphabets were invented in the written form. This helped in the introduction of postal service. This way communication between different parties was made. But for long distances it became difficult.The Chinese invented paper and the book came by 100AD. Slowly all the writings were entered into the books. Books were best for storing informat ion for a long time without causing much damage. Newspapers were introduced into the Europe by 1450AD. Newspapers were the best way to know about the issues happening nationwide. Joseph Henry invented the first telegraph in 1831. With the help of telegraph, information was passed much quicker compared to others in those times. The biggest invention of the 19th century was the telephone. Nowadays we can’t imagine the world without a telephone. Slowly one after the other motion picture, the radio, television, computers, etc., were invented.... With the help of telephone communication between people became much faster. Nowadays we can't imagine the world without a telephone. Slowly one after the other motion picture, radio, television, computers, etc., were invented.In early centuries transportation was carried out with the help of bullock carts, horses and other means. For short distances they were effective but were not that much of help for long distances. Slowly as the centuries gone by many different transport systems were invented and introduced into the market. Ships, trains and automobiles revolutionised the transport system. Long distance travelling was made safer and much better than the earlier ones. Ships and trains were not only used for transporting passengers but also used for transporting large cargo. These transporting systems were very much comfortable to the passengers. Biggest achievement during industrial revolution was the introduction of trains. Railroads played major role for the success. Many railroads were laid across different countries. With invention of steam engine trains were travelling at much higher speeds. Long distances were covered in short periods. Nowadays bullet trains were introduced. They travel at a speed of more than 400 km/h. Here space was covered at fast pace. We could say that time and space was collapsing. One of the biggest inventions of 20th century was the aeroplane. The Wright brothers were the first to invent it. Slowly after making many modifications it was used for transportation. To be airborne an aeroplane has to travel at a speed of more than 90 km/h. Now jumbo jets are used for transporting people. A single jumbo jet can transport more than 300 passengers. And these can move more than 1000 km/h. Concorde can

Assessing risks arising from contamination of the aquatic environment Essay

Assessing risks arising from contamination of the aquatic environment with Bt toxin from GM corn (maize) crop litter in the USA - Essay Example (National Agriculture Statistics Service, 2009) Hypothesis: To find out the impact of BT toxins on the aquatic environment if used without extensive risk assessment. What is the first impression you get when you hear the term, â€Å"Genetically Modified Food†? In recent years, speculation has renewed over the full effects, and possible consequences of genetic modification of organisms for the production, and augmentation of human food supplies. It is worthwhile to identify the specificities of the techniques involved to produce BT crops, as well as other biotech innovations. To understand potential environmental and biological risk factors involved we must delve into precisely what does and does not occur with genetically modified crops. This study will explore techniques involved in producing genetically modified foods, their importance to agriculture, and the nature of the BT molecule/toxin. In addition, two other research projects will be summarized which explore possible s ide effects of BT toxin dispersing into the environment, as well as the frequency of that dispersal in the water table. BT technology must be a subject of discussion, both due to the popularity of this technique, by which pesticides can be incorporated directly into plant tissues constitutively – and the possible far-reaching ramifications of such an inclusion. Both of these studies focus on corn/maize due to its prevalence – but virtually any vegetable that has utility for humans is a possible target for genetic modification, in the interest of greater profit towards an increase in the human food supply. GENETIC MODIFICATION Genetically modified organism(GMO): An organism is "genetically modified", if it’s genetic material has been changed in a way that does not occur under natural conditions through cross-breeding or natural recombination. Bacillus thuringiensis (Bt) is a spore forming bacterium that produces crystals protein (cry proteins), which are toxic to many species of insects. (University of California San Diego) GM crops are made using technology which allows Bt toxins to be introduced into crops, making them resistant to pests. For centuries, human beings have attempted to incorporate desired traits both in animals and plants of human utility. Selective breeding has been employed to both as a means of eliminating undesirable traits, such as excessive ferocity in certain breeds of dogs, and greater sugar content as well as size increases for fruits and vegetables. Using ancient techniques agriculture was limited to working within a single species in order to identify desirable, and undesirable traits - and then through successive generations to concentrate those virtues within the species that proved of highest economic benefit to humanity. Or as the case may be, to winnow out those traits that ran counter to human interests. Genetic modification broadens the set of tools available to agriculture, agribusiness, and eventually to animal husbandry. What if we were not limited by the genes within a single species? What if it were possible to use genes from virtually any species and incorporate them into crops? Perhaps the particular globular proteins present in a deep-sea fish which
