The given line graph represents millions of tons of air pollution in UK, from three different sources, between 1990 and 2005.
Overall, it is clear that the total and industrial pollutants have gradually decreased all over period. While transport and households stay steady from 1900 to 1999. Nevertheless, according to the line graph, the pollution of transportation is drastically increasing next following years. Whereas, in 2005, households’ pollutant is the lowest one on the figure.
First of all, it is clearly seen that, the numbers of industries and total air pollutants saw an approximately negligible amount of decline throughout the course of three years. However, the quantities of transport and households remained unchanged between 1993 and 1996. Following six years (1993–1999), we can see that, the figures for the industry, total air pollutants and households, faced plummet. Although, the amount of transport level off at overtime.
Secondly, turning to the next years (1999-2005), as line graph illustrates, before the number of total air pollutants go down in 2005, it remained only 3 years, more precisely in 2002. If we look at the numbers of industry and households, they dropped by around 50% to 1-3 million tons, cases. The amount of transport remained its number as always, more accurately, its rate was estimated at approximately nearly 1-2 million tons during quindecinnial.
