<p>Question: Do changes that make our lives easier not necessarily make them better?</p>

<pre><code> Changes that make our lives easier do not necessarily make them better. Easier and better are two distinct words with two different meanings. There are many examples of changes which have made our lives definitely easier, but not better. Cars that run on gas, smartphones with all its applications, and the monotonous dishwasher are all exemplary models of easy lives with disadvantages.
Today in America, more than 80% of the U.S. citizens own an automobile supplied by gas oil. There is no doubt that these machines have revolutionized transportation in our lives, but the gravity repercussions society faces in result prove to be detrimental for the future generation. Now we can drive from Irvine to Los Angeles in about an hour while walking would take more than eight hours of constant walking. The efficiency of cars and its effectiveness is proven but the damage our world suffers from the pollution is even more significant.
Not only automobiles, but our technology in smartphones has made our lives easier, but arguably not better. Through the phone's multifunctional features, owners of smartphones have access to myriad types of action. Evidently this technology grants us with knowledge and possibilities but it also creates laziness and lack of movement. Many teenagers and adults alike spend at least 2 hours on their smartphones according to a research. Our loss in physical functuality is much more impulsive than extra knowledge through our smartphones.
Last but not least, most homes in the U.S. own a dishwasher unit which reduces an average housewife's 30 minutes of labor. Yes, it is time saving, but after the processing of the dishwasher, one often spots the flaws of machinery through unperfectly washed bowls and dishes. The dishwasher makes a person's homelife easier and saves time, but is the reduction of 30 minutes of dishwashing really worth the problematic machine?
All in all, there are changes in our lives that seem to be efficient and useful at times, but they don't necessarily make our lives better than before. In fact, referring back to the polluting of car engines, some changes in our lives worsen the conditions of our natural world. One should be able to identify the distinction between better and easier for the sake of our natural world. One should be able to identify the distinction between better and easier for the sake of our world and its people.
