The lecture opposes the view mentioned in the reading with strong supporting evidences presented, aiming to further illustrate that the limit access to internet use is not as effective as stated.

Firstly, From the perspective of email filter, the professor states his doubt, because according to the lecture, the filter is not effective to those who maliciously expose secrets of the company, in the use of innocent words, which the filter cannot effectively screen out.

Moreover, judging from the streaming media, the professor holds a different view, as the lecture further illustrates that it is not necessary to spend that much blocking all the streaming media, only 10% of which is effective. According to data, the limit to the most common streaming media, such as websites of pop music and videos, is effective enough.

Last but not least, on the point of zero access to internet, the professor never fails to express his concern, because in terms of the listening, those staff in the company allowing free internet access are of better creation, as they believe they are trusted by the company, and will behave in better morality in return, working hard and longer in the company.

Back in the days, the world suffered from instances of food-related issues such as shortage, sanitation, and nutritional content. Today, with the numerous advances in related fields of technology, most if not all, of these problems are just a memory of the past. Many claim, in particular, that the foods we consume today are of a much higher quality, thereby making them healthier to eat. But is this certainly the case? I don't think so.

The last time I checked, there were lots of fast food chains sprawling in our cities and even in some suburban areas. In these places are common sights of obese children and other unhealthy-looking consumers. It does not stop here. The situation gets worse. Remember the time that the price of staple food like rice was sky-high because of limited supply? Well, that's not the case now. However, there were news reports showing that most of these food supplies, though plentiful, lack the necessary nutritional content. Certain varieties were even proven to be harmful instead. Does the term Genetically Modified Organisms (GMO) ring a bell? In spite of our efforts to produce agricultural products with higher yield, the main concern seems to be this. Are we really eating healthier food now?

Food fuels us. Depending on the quality of food we eat, our resistance to sickness, fatigue, and overall wellbeing is determined. Then how come most people now easily get sick or die early? Yes, there are other factors to consider like air pollution and the likes. However, food forms the large proportion of our requirements for survival and daily accomplishment of our activities.

This being said, I firmly conclude that the foods we eat today are not as healthy compared to those in the past. Despite the advances of modern technology, certain by-products are inevitable. Thus, it is up to us to effectively filter what goes into our mouths lest we suffer from unhealthy foods' effects.
