Loud‚ aggressive‚ and fast‚ metal music has been accepted worldwide as an acceptable genre of music. Yet‚ some people cannot comprehend a genre of music that thrives on being the horror movie of music‚ and purposefully creates controversy at nearly every turn. “The media has irresponsibly finger-pointed” (Sterngold). One of the most recent examples of metal being blamed for a national tragedy was in the shooting of Congresswoman Gabrielle Giffords. Here‚ a song by Drowning Pool was blamed as the

heat affects metal when it is being welded (peasecha) Charles Pease 3-29-16 English 10 How heat produced from welding affects metal The heat produced from the welding process can cause deformation and can also cause changes in the metal at a molecular level. This can make the metal brittle and even deform it. When the arc is struck and the metal starts to become molten it reaches temperatures in an excess of 8‚000 degrees fahrenheit and such a large input of heat into the metal begins to move

enter the soil. Nevertheless‚ heavy metals are the most toxic of all the pollutants. Among these‚ lead‚ cadmium‚ chromium‚ mercury and arsenic are most toxic and can cause multiple organ damages even when present in small amount. Although‚ these elements are necessary for soil animals as well as plants in extremely low quantities. However‚ anthropogenic activities like mining‚ smelting‚ fuel burning etc have disturbed the natural geochemical cycles of heavy metals which raises concern over their management

Some of these false reasons include violence in most video games‚ certain foods‚ or certain music. Metal music being a cause to hostility is beyond ridiculous. It’s time for the truth to be revealed about this lie that social media and society has implied upon. Metal music can actually raise your implicit feeling and thoughts of yourself. For example‚ many bodybuilders choose to listen to metal because it’s believed to keep them going and enabling them to reach their maximum lifting capacity. The
