science
subjects in universities in many nations as it is obvious that some prefer other subjects
instead

this
problem, and
also
some effects on society. There are several main reasons why people who choose

decrease. On the one hand, one of the most important reasons is satisfaction in their job.
This
is because, nowadays, there are many jobs, which do not have to learn
science
,
such
as commerce, designer, and director.
Moreover
, some think that
science
is more challenging than others because of complex concepts.
Also
, curricula
such
as chemistry, biology, and physics require a dramatic investment of time to understand
this
subject. Another significant reason that students choose
science
is the opportunity to select a career after graduation
such
as a variety of jobs or salaries. The explanation is that
due to
specific sciences
such
as doctor, engineering, and veterinary, they have much work, in which they learn.
In contrast
, graduates who learn other subjects do not work in what they are educated.
However
, there are effects on society when not enough students are interested in
science
