The Process of Harnessing of Energy - Assignment Example

Therefore, they drill into the earth’s crust and pump in water. The principle of contraction and expansion works best here. When cold water comes in contact with the hot rocks, fractures develop on the stones, thus giving room for water to move horizontally towards the already drilled second hole. Steam escapes through this second hole to reach the earth’s surface. Depending on what has been set up, the smoke can be used in turning turbines or steam engines (World Nuclear Association, 2013).

Permanent disposal of war nuclear waste is increasingly becoming a problem because it takes a long time for the waste isotopes to decay into safe levels. Even though waste management specialists advise users to bury such wastes deep below the ground, it is easy for particles to move, thus causing ethical concerns.

War significantly impacts the natural environment since it causes massive pollution to water sources, soil and air. For instance, the Iraqi war of 2003 led to enormous death among people. Blue plastic barriers with a high level of uranium oxide got lost but dumped in the river for borders (Cardona, 2004). Residents unknowingly used the containers to store water and other foodstuffs. Since then, there has been an increase in death due to leukaemia.

Another example is the Gulf war of 1991, where Iraq and Kuwait differed over oil fields. In response, Iraq dumped nearly two million tons of crude oil in the Persian Gulf. This had a significant effect on marine life. People living by the shows died due to brain cancer and kidney failures.

For some reason, nuclear energy is good. However, it has long negative impacts on the environment. This is evident through the significant wars the world has experienced. The Hiroshima bombing in Japan still has effects on the city occupants. The radiation results have led to gene mutation and infertility in some cases. Nuclear energy use is an expensive venture and an environmental risk.
