The line graph illustrates the proportion of acid rain produced in millions of tonnes in the UK from four categories between year 1990 to 2007.
Overall, almost all the sectors experienced a decline in trend. Other industries and electricity, gas and water supply saw a gradual fall in acid rain emissions. Whilst, transport and communication underwent a steady rise until 2005, afterwards, it dipped till 2007. Moreover, domestic industry had a slight decrease with a steady pattern.
Firstly, electricity, gas and water supply started off at about 3.25 million tonnes as the highest producer of acid rain in 1990, but fell gradually by a significant amount until 1999 and then dropped steadily uptill 2007 until it became 0.5 million tonnes. Furthermore, other industries stood at just above 2 million tonnes for the initial three years until a gradual decline uptil 2007 where this category stood as top contender at producing acid rain.
Lastly, the remaining two industries started off justover 0.5 million tonnes, where transport and communication steadily increased until it reached a peak of 1 million tonnes and then dropped by one-fourth of a million tonnes by 2007. Additionally, domestic sector remained unchanged for the first 4 years until it decreased gradually to become the last producing acid rain industry in 2007, emitting just under 0.25 million tonnes of acid rain.
