The first bar chart illustrates the proportion of students by gender in one university who chose to study science subjects in 1992 and 2012. The second chart provides information on the most popular science subjects chosen by these students.
Overall, it is clear that a higher percentage of male students chose science subjects compared with female students. In both years, biology was the most popular science subject among students.
In 1992, 46% of male students studied science subjects, but this proportion fell to 34% in 2012. In contrast, whereas only one-quarter of females chose science subjects in 1992, this increased to 32% in 2012.
Despite a decline from 40% in 1992 to just over 30% in 2012, a higher proportion of students preferred to study biology than other science disciplines. However, there was a significant increase in the popularity of computer science among students, with this figure rising from just 10% in 1992 to 18% in 2012. The figure for those studying physics remained the same at 25% in both years.

It is true that the environment is being damaged and that one of the causes of this is the growing output of consumer goods. While some reasons can be identified to explain why this is happening, there are measures which should be taken to deal with this issue.
There are important ways in which the production of more and more consumer goods is resulting in an ecological crisis. Firstly, in order to maximize profits, corporations are depleting natural resources. For example, energy is required for all production processes, and so the search for oil and gas reserves has led to habitat destruction as well as repeated oil spills threatening marine life in the oceans. Secondly, toxic waste is released into our environment in the process of producing consumer goods, such as dyed fabrics or detergents. Finally, the packaging of consumer goods to make them look attractive has resulted in a huge volume of plastic waste which is simply dumped.
Ways must be found to alleviate such environmental problems. In terms of energy management, public subsidies must be provided for the expansion of renewable energy. In many parts of Europe, for instance, offshore wind farms now make a significant contribution to the energy needs of industry. From the perspective of reducing waste and limiting pollution, there should be research into producing packaging for consumer goods that is bio-degradable. Governments must also exert pressure on producers to cut down on emissions from factories and to fine companies which pollute the land, water or the atmosphere.
In conclusion, while some reasons can be identified to explain this problem, effective measures are available and must be imposed to make the production of consumer goods more environmentally-friendly.
