* Scientists die in labs because of accidents.
* Too many species to keep track of.
* Animals disturbed from habitats.
* Plant species taken from environment.
* Rare species threatened.
1. Can be easily manipulated by irresponsible persons.
2. We'll be too dependant on it. When technology fails, we r helpless (in one way or another). 3. Sometimes, it affects our health and lifestyles(we'll be complacent and lazy. The chemicals r hazardous). 4. It destroys our simple and healthy life(I miss the traditional style of living). 5. Invasion of our privacy.
6. Science can pollute waters.
Since the 17th century science has entered into the modern age of its development. Science, which is based upon the knowledge of five senses, has stunned the world with great astonishment. Particularly the last half of the previous century and the beginning of the present century have contributed much more regarding developments in the field of science and technology. It is also an accepted fact that science has very much revolutionized the world. It has made everything very easy and accessible. No doubt science has brought astonishing changes in the field of health, defense, education entertainment, communication and social life. The conclusion can be drawn as the present world has been changed into a global village via communication advancement. No one gets bore by having the cheapest and easiest means of entertainment. This he enjoys only through science, similarly almost any new disease can be cured easily before spreading in the other places. It is also an unveiled fact that news in one part of the world gets stale in the other part of the world just within minutes only due to advancement in communication, a success of science in this world. The air journey, the voyage in the ocean and the journey on road have been made comfortable, facilitated and quickened by the inventions of airplanes, bullet trains; air conditioned buses and coaches and ships containing restaurants and hotels. In a nutshell, the list of the benefits from science is unlimited due to greater number of inventions in every field. Though, its usefulness and benefits can't be ignored, science has also brought in some harm through its inventions. Science definitely has disadvantages. Human being seems very exhausted, bored and a bit confused due to its harms. For starters, consider the example of very big and destructive weaponry, advancement in the field of weapons. It is science which has introduced atomic bombs, Intercontinental Ballistic Missiles (ICBM), air jets, B-52 bombers, pistols, guns and the list is long.
2. Disadvantages of Technology
It would not be exaggeration to say that the whole world can be destroyed just within few minutes by atomic bombs. It has already been witnessed that detonation of such bombs anywhere can destroy everything that comes under its influence and in many cases such areas becomes barren for years if not centuries, Hiroshima and Nagasaki are classical examples of such destruction. Similarly, science has made man very lazy in his temper and practice. His attitude has been changed in a different way. The goal of technology was to help man in achieving his goals easily, but due the abusive nature of human beings, technologies bring more harm than good. But this does not mean that technology is solely responsible for all the harm, human beings play a crucial role in the abuse of technology. Technology by itself does not do harm, it is the user who misuses technology and causes harm to the society. In other words, man's efficiency and output in performing many daily works has been reduced. What happens is that when he is deprived of such facilities due to poorness or other inappropriate circumstances, he feels great stresses and also realizes his inabilities, thus making him extremely dependent on technology. Similarly, problem of pollution can be...
