The given line graph illustrates the figure for carbon dioxide emitted by each person in four countries in Europe over a span of 40 years, from 1967 to 2007.

This

table clarifies the numbers of toxic gases consumed by people in the United Kingdom, Sweden , Italy and Portugal in the 21st century.

Overall

, we notice from the line the amount of CO2 gradually increased. In 1967 , the high use of carbon dioxide in the UK was about 11

tonnes

while

Portugal emitted only 1.5

tonnes

.

This

situation has been continuing since 1977, indeed, the amount used for these materials in Sweden jumped to 10

tonnes

. The numbers in 1987 indicated to rise in taking these hazardous materials with some differences, the figures in Sweden dropped to 6

tonnes

,

whereas

, in Portugal, there was a drastic change from 2 to 4. In 1997 the Same thing happened

while

the use of

this

carbon dioxide decreased smoothly in the UK. In 2007, the use of

this

toxic carbon had been falling in the UK,

however

, in Italy had been sweeping.

To conclude

, generally, we notice from the statistics that the number of consuming emissions is increasing each year.
