The given line graph indicate the degree of pollution in UK’s atmosphere, from three different sources – industry, transport, and households – and its total per year from 1990 to 2005, in million of tonnes (as a unit of measurements). In general, the total amount of pollutan in UK’s air showed a downward trend. Moreover, the most significant condition was showed from the industrial resources, while the stable one was came from households.
Looking in detail, in 1990 pollution which come from the manufacture section was the highest in the figure and illustrated the general declining. Meanwhile, in the same year, the transportation and residential sector start with the number that much smaller, 1 million tonnes. From the starting point, transportation contributed pollutant in the air by fluctuating trend from 1990 to 1999, then gradually increase between 1999 and 2005.
The source from residential’s sector did not make a progress within nine consecutive years (1990-1999), represented by the line which remain in the similar position (1 million tonnes). After steadily unchanged, in 2005, the amount of air pollution which is supplied by households was hit the floor of the graphic (0 million tonnes) and it was indicated that the air pollutants were dip to zero.
In conclusion, pollution in the UK’s air was declining from 1990 to 2005, and the highest contributor was come from manufacture while the least one was come from households.
