Two Things I Would Change in the World free essay sample

Two things I would change in the world The world has become a chaotic and a challenging place to live in. It is tough to choose only two things that the world should change, that’s why I am a strong believer of chain reactions. It was in 1913, when Max Bodenstein, a German chemist, first introduced this idea. What about changing something relatively small to achieve a bigger and major change in this enormous world? It is common knowledge that environmental problems are getting worse every day. For a long time now, generations have been partially negligent about these issues. The world is the house of humanity: if we make our best to keep our houses clean and tidy, why not doing the same thing with our planet? In my opinion, hybrid cars are a huge component of the future of environmental awareness. Petrol cars should be replaced for hybrid cars.

It is true that the electricity used to charge electric vehicles comes from a  source that emmits CO2, but this CO2 production is aproximately one-half of a combustion vehicle. Then, hybrid cars are not only a way to reduce polution, but also a way to avoid the crisis after the peak oil (a peak oil is the point in time when, after the maximum rate of petroleum extraction is reached, it declines). By making the petroleum industry dispensable, the planet would have even more advantages. First of all, oil extraction is costly. Oil spills have made huge damages on environment for years, and the planet was obliged to spend thousands of dollars in that account. Reducing spending in oil industry would allow investing in newer and safer fuels. On the other hand, HIV/AIDS is an increasing threat for world population. Recent research about a new vaccine for halting the contagion should continue.An HIV/AIDS vaccine would mean no daily treatment for diagnosed patients, and a smaller spread of the virus. In 2007-08, the first â€Å"cured† patient was introduced: the â€Å"Berlin Patient† had two stem cell transplants as a leukemia treatment, and 20 months later, HIV levels in the patient’s blood were not even detected. This is a major breakthrough in the future of AIDS. The most affected region is the Sub Saharian Africa (about 10% of children deaths are caused by AIDS, and 5% of the adult population is infected); this leads to a really low life expectancy at birth in these countries.Having many diagnosed patients in a country means  decreasing human capital, increasing medical care needs and decreasing taxable population, and that altogether reduced gross domestic product. Surpressing HIV/AIDS in emergent and developed countries would, perhaps, end with thousands of avoidable deaths each year, and consequently, would allow bigger economic growth in the poorer countries (the most affected by the virus). I have chosen these two things because, through chain rea ctions, they would bring a significant improvement in quality of life of all mankind.
