In the past, knowledge was stored in books. However, now it is stored on the internet. Do the advantages outweigh the disadvantages?

In recent decades, as the advance of technology, using electronic books instead of traditional books has been increasing considerably. Although it has a negative influence on e-readers’ health, it is an eco-friendly alternative for us to protect the environment, which far outweighs any drawbacks.

On the one hand, there are several drawbacks of reading books on the internet, one of which is that it has a negative influence on the health of readers. To be more specific, when they use ebooks, they have to look at the device's screen, so they have to get exposed to the blue light of the screen, which is not good for their eyes. Therefore, these people easily suffer from eye-related diseases. For instance, a recent study of Foreign Trade University in 2019 showed that 72% of students here were short-sighted since they read ebooks from 2 to 3 hours per day. However, electronic devices these days come with features where users can adjust the brightness of the screen according to the time of the day, which enables them to protect from eye damage.

On the other hand, ebooks have been becoming more prevalent because they are environmentally friendly. In fact, if the traditional books are replaced by ebooks, the amount of paper production will be reduced tremendously. In other words, the requirement of cutting down trees will be decreased, which might mitigate the effect of greenhouse gases and global warming in the long run. For instance, a recent study from Harvard University indicated that in 2019, the dominance of electronic books over printed books lowers the risk of 195 plants logged, which lessen 10 times of CO2 releasing into the air. This means that switching to ebooks enables people to protect their environment as well as to expand our longevity in the future.

In conclusion, while it is quite dangerous for people’s health to read books online, ebooks allow us to protect our environment, which outweighs the merit.
