Chemistry Pros and Cons

The biggest concern is a person using chemistry for negative means. Basically, the amount of energy is constituent atoms, which can help build things, help destroy things faster. I will outline 3 principal concerns below:

The first one is the obvious one - Nuclear Power. There are two basic nuclear reactions: Fission and Fusion, involving breaking up or fusing of atomic nuclei. When nuclei fuse or break apart, they turn into other elements, giving out Energy. This can be related to Einstein's famous equation where the "Mass" from the nuclei is converted into pure "Energy." This principle can be used to power a generator to produce, in a sense, a LOT of electricity. But a fateful day in Japan, 1945 reminds us the vicious power of Nuclear Fission, where the Atomic Bomb, caused devastation, and still affects the area today. Also, incidents at Chernobyl and more recently, the Fukushima nuclear meltdown tell us that if not controlled, the vicious energy can destroy the entire planet.

My own take on the Nuclear theme is - Right now, we are at the brink of mastering Fusion Power - although complete mastery is still decades away. After Nuclear Fission is mastered, we may 'export' the Sun to Earth and start a Nuclear Fusion reactor. Nuclear Fusion is far better than Fission, and also does not produce waste by-products. So, until we master Nuclear Fusion, this is an intermediate step.

The second one is - Biological Terror Attacks. Although the name tells us its got something to do with Biology and Diseases, but advances in chemistry can mean terrorists deliberately spreading toxins, harmful gases, viruses and likewise among the masses. The 2001 US Anthrax attacks, where letters were laced with infectious material, are a prime example.

The third is the hot issue - found everywhere in science - Global Warming. The CFCs, Carbon Monoxide, Carbon Dioxide were all, in the respective eras, were found as solutions to certain problems. The Greenhouse Effect, a...
