A Pessimist: The greenhouse effect is warming the earth, the glaciers are melting, the weather is running amuck, acid rains are slaughtering the woods, chemicals are eating up the ozone layers, the ultraviolet sun radiation is frying us alive...
An Optimist: Yes, what a great opportunity to do business!
kiwi , i will be a pessimist at this one .the rain use to a blessing for us in africa. but now it seems it is either too much or too little. what will happen if the technology is misused and rich nations continue to give a blind eye to the mounting global warning. jack you will soon be needed to assist us in scientific matters.
Surah- Ar-Rum 30-22 "And among His signs is the creation of heavens and the earth, and the difference of your languages and colours. verily, in that are indeed signs for men of sound knowledge." Qu'ran
Pessmists and Optimists are two sides of the same coin. There are costs and benefits to Global Warming. However the situation becomes alarming when the costs out way the benefits.
