The line graph indicates the UK acid rain emissions over 17 years

The line graph compares four various sectors in terms of the amount of acid rain emissions from 1990 to 2007 in the UK.

Overall

,

it is clear that

transport and communication rose significantly over the period given.

In contrast

,

electricity

,

gas

and

water

supply and domestic and other industries registered an enormous decline.

Moreover

, it is noticeable that transport and communication and

electricity

,

gas

and

water

supply showed a similar trend between 2001 and 2003. As can be seen,

electricity

,

gas

and

water

supply reached a peak at 3.4

million

tonnes in 1990.

Nevertheless

,

this

sector had a mild fluctuation from 1997 to 2001 ranging between 1.4 and 0.9

million

approximately. The figures for

electricity

,

gas

and

water

supply decreased sharply to 0.5

million

in 2007. Domestic and other industries stayed constant at the beginning and end over the period shown.

On the other hand

, transport and communication increased gradually until it reached a peak at 1

million

in 2004.

Likewise

, it remained constant from 2004 to 2005 and

then

dropped dramatically to about 0.7

million

.
