  • Fiberglass

    Fiberglass is actually plastic wrapped in glass composed of plastic. It enters the environment through manufacturing, using, and disposing such materials. Damaged materials, such as fiberglass insulation, could possibly release fibers into the air and could eventually blend with other airborne particles as component of dust. This exposure can take place through ingestion, breathing or even skin contact. Moreover, such effects can ordinarily take place through home maintenance or moving materials which contain fiberglass. When fiberglass reaches the lungs, it could easily remain there and case numerous health problems, such as the elevation of asthma, damage of cellular mechanisms, and the promotion of cancer cell growth. However, despite the few negative effects, fiberglass does happen to be quite environmentally friendly: It features the lowest embodied energy in comparison to other window frame materials, provides the longest life expectancy,  and has self-extinguishing capabilities in case of fire. Additionally, fiberglass provides stable tolerances and high quality throughout the production phase.

    The iPod is a portable media player that was designed and, now, sold/marketed by Apple. The company has designed 4 varieties of the iPod: iPod shuffle, iPod nano, iPod touch and iPod classic.  IPods can be used to store music, photos, videos, games and much more; nonetheless, how much iPods can store depends on the storage capacity, which is different for each model. The capacity of the iPod can vary from 2GB, which is usually found in models like the iPod shuffle & iPod nano, to 160GB, which is normally the case with the iPod classic. This product is considered convenient and worthwhile, which is why it is so popular and still bought all over. Whenever an athlete wishes for the time to pass while running or a teenager feels bored on his/her way to school, the iPod is always a solution for such cases.

     

    Although the iPod is such a beneficial and beloved product, it does happen to be the cause of numerous negative effects on society. Firstly, despite the fact that people are aware of the results of listening to their iPods while driving, people do so anyway. This frequently leads to many car accidents as people forget to concentrate on the road. The same happens with those going by foot or by bike, as they also neglect the fact that they might get run over because of the music playing in their ears. Moreover, iPods also create antisocialism, as people now prefer to listen to their music rather than to interact with their friends/acquaintances. Logically, isolating oneself from the rest of society could lead to many problems later on. Furthermore, people that listen to music too loud also receive hearing problems early on. The pressure of the high volume on a person’s ear drums causes either periodic hearing loss or, sometimes, permanent hearing loss, depending on how badly the individuals’ ear drums is damaged. Lastly, the fact that illegally downloading music has become an ordinary thing is very problematic for the music industry. When people download the music without paying, the music industry loses a lot of money as a result of the record sales that drop immensely.
