WHY IS THE SKY BLUE? I don’t suppose you happen to know. Why the sky is blue?It’s because the snow. Takes out the white. That leaves it clean. For the trees and grass to take out the green. Then pears and bananas start to mellow. And bit by bit they take out the yellow. The sunsets, of course, take out the red. And pour it into the ocean bed. Or behind the mountains in the west. You take all that out and the rest. Couldn’t be anything else but blue. Look for yourself. You can see it’s true. from «Why the Sky Is Blue»by. Jonn Ciardi

Dear Ellen,the problem of ecology is very urgent in Ukraine. During the last 50 years a great deal of forests in the Carpathians have been cut down either for firewood or for timber products. Deforest ration has led to changes in local climate. That's why we have so much trouble with in this region. Air pollution can also cause water pollution called "acid rain". Then this acid rain water runs into rivers, fakes. They become so dirty that fish cannot survive. Some factories produce liquid wastes that run into rivers. These wastes contain poisons. One more example of making the environment unhealthy by human activities is the application of pesticides which enable farmers to control weeds. At first bumper crops seemed guaranteed. But then things went wrong. Weeds and insects proved resistant to the pesticides that were poisoning the insect natural predators, the wildlife and even man himself. Environmental degradation of our planet is a great threat to our future. Speaking about our country / couldn't but mention1 about Chernobyl nuclear break-down. Radiation has become one of the most urgent problems because it may cause changes in human genes. These are only some of the serious ecological problems in Ukraine. Nothing on the earth is more important to our survival than the air we breath, the food we eat, the water we drink. That's why we need to take measures to change the environmental situation. Sincerely Yours,Iryna
