What do you consider the most important invention of the last 200 years?

In my opinion, the most important invention of the last 200 years is the automobile. This invention represents one of the biggest changes around the world because people used to use horses as their vehicles, but with the introduction of the first car it meant a lot of time saved. It also means people had been losing money before cars arrived because of the wasted time. 

With the time, automobiles were common to find in families just for their transportation. Nowadays it’s a necessity to get a car in order to come early to the job, be prepared for any emergency, etc. Nevertheless, automobiles are first polluting agent because for their exhaust gases witch cause a big impact directly to the ozone layer increasing the global warming. Furthermore, automobiles have one of the largest rates of death caused by an unrestrained negligence of drivers.

In my opinion the most important invention of the last 200 years is the digital camera because you can reminisce just with looking at a picture. Personally, it is interesting the way you can capture many moments just with touching one button. And now, with the help of technology it is easier. There are benefits and disadvantages to this. One advantage is that it’s easy to carry because nowadays digital cameras are becoming smaller with the pass of the years and you can put it in your jackets and that is all! Another benefit is that digital photos can be retouched/fix. For example, now there are a lot of websites where you can “fix” your photos. There is another positive thing like now digital cameras take both photos and videos. In my opinion this is a good thing because you won’t have to buy a separate item. But there are also some disadvantages to this. One drawback is the quick change of models of the same brand. For example, I remember when I bought my first digital camera, it was the ultimate model but in the next month there were better one. Another downside to this is the accumulation of hundreds or thousands of photos. Take for example the case of my sister, she always forgets that she has those photos and that is how photos are forgotten.
In conclusion, digital cameras are good because they allow you to take as many photos as you can but you don’t have to forget about the developing. I also think that digital cameras should be easier for some people because for some of them it is difficult to learn how to use it.

In my opinion, the most important invention in the last 200 years is the Internet. This invention was created around the 80’s and 90’s. In the beginning, a lot of persons tough wouldn’t be so important and needed like nowadays, but they get wrong. This tool now, it’s part of our life, it’s needed for different things like communication, complete a homework or an assignment or even to know the news. Persons of all ages and countries use it, teachers, students, parents, bosses, etc. But like any other important invention, it have benefits and disadvantages. The benefits are that this tool can replace a lot of things that nowadays are common but old. For example the newspaper, the internet is like an universal newspaper, it have everything you will like to know, not only from the present, it have the info of things of the past and even from the future. Another advantage is that with the internet our society keeps going forward with the technology and don’t stand in the same place. Also you can communicate with long distances friends and familiars, you can meet new persons, and make new friends no matter from what places you both are, you only need to have internet.

But the disadvantages are more; the internet could be also dangerous, for example, when you meet a new person from internet, you could think that the person you are talking with is the person he says he is, but how are you sure he is that person really, now there are a lot of ways to be sure, like videos and voice mails, but no one never is 100 percent sure. Maybe it could be a person that wants to make you feel sad, maybe for revenge or any other reason, or even could be a person that only wants to hurt you. Like this there are a lot of this advantages, so you have to know, that this is a very useful tool but also it can be a dangerous weapon, so always use it with straight care.

I consider social networks the fastest way of communication, so that is why for me social networks like Facebook, twitter, yahoo or many that exist in this year are so important for people worldwide.
Some benefits that social networks have is that teenagers can communicate faster with people that they love and maybe they are in another country, also they can share information with a group of people in order to do a good project; thy can get information to improve their knowledge. They can build their personality with a face to face conversation with friends and do also a mutual support with them so they can have a good social life.
There are also some risks that the parents need to see in their daughters because they can start a conversation with someone that they don’t know, social networks can create in the person the necessity to use it all the time and with this they can have problems in school because they didn’t study for a final exam or they didn’t do the homework. Sometimes there are a lot of cases of bullying, but with social networks it is called cyberbullying and it is a bad problem of our society that we have to eradicate.
The phenomenon of social networking has taken today’s youth culture by storm. At the same time, it has raised serious problems as the ones mentioned before, so that parents need to take a step back and get to know the facts of the matter and learn more and more about the pros and cons about social networks.
