The use of CFCs in Products like hair sprays and refrigerant gas for refrigerators and Air Conditioning systems has created a hole in the ozone layer. CFC
Scientists have recently reported that the Polar ice Caps are melting due to a rise in atmospheric temperatures known as the “ Green house effect “.
.
.
The reduction of this protective layer, has caused many more Cases of skin Cancer.
.
Construction on the house began in April 1994 and ended in April 1995. Monitoring of the system began in June 1995 and a year,s results are now available.
. . If you want to weld stainless steels Properly and Produce a sound weld, do not forget Post- weld cleaning.
.
the world we live in
The carbon dioxide given off when Coal and oil are burned is accumulating in the atmosphere and causing temperatures to rise,we call this “ Green house effect “.
. The “green house effect“ is just one of many fundamental changes which are taking place in the environment.
. The butning of gas, oil and Coal has created Acid rains and these rains are damaging forests and making the most beautiful lakes of the word lifeless.
