There are some clear reasons why fewer students are now interested in science subjects. One major reason is the difficulty of these subjects. Students have to solve perplexing math, physics, or chemistry problems, which can discourage many students from STEM subjects. In addition, the influence of families is another reason. In some countries since lawyers and businessmen make a great amount of money and are valued in society, parents force their children to study non-science subjects.
This trend can affect a country negatively. There might be a shortage of skilled people in engineering. Engineers play vital role in a thriving economy. When there are not enough of them, a country's economy needs foreign experts for its industries. Another consequence is not being able to address environmental issues. A country needs experts to tackle environmental concerns, such as air pollution. A lack or even a shortage of such experts can exacerbate these problems. Moreover, the imbalance in the workforce is another consequence. More people studying non-science subjects means more experts in other fields. This in turn, can lead to unemployment in non-STEM subjects. A clear example of such a country is Iran, where the vast majority of students have chosen to study medicine or veterinary and such fields are highly saturated.
In conclusion, the difficulty of science subjects and the role of parents in encouraging their children to study other subjects are two main reasons why fewer students choose to study STEM subjects. Consequently, a country with this trend will face problems in its economy and suffer from environmental issues and many unemployed people in other fields.
