Most of the talk these days is about global warming. a major report on global warming has warned that average world temperatures may rise by several degrees in the next century, due to the build-up of "greenhouse gases" in the Earth's atmosphere. as the Earth gets hotter, the ice caps and glaciers may melt and sea levels may rise. it's time for action before we're all sunk! let's become environmentally-educated.

Every year more and more plants and animals disappear never to be seen again. in many lakes and rivers fish are dying and some lakes have no fish at all.
Тrees are also in serious danger. this new danger attacks all trees like oak, beech and birch as well as fir tree and pine. first the branches turn yellow and brown. then the trees' needles or leaves fall. the roots and the trunk shrinks. finally the trees die.
What is killing fish and trees? the problem is acid rains. factories, power stations and cars emit tons of smoke into the air. the smoke contains substances which mix with water vapour in atmosphere and form acid. sunlight turns these acids into poisonous oxidants which fall in rain. the wind carries the poisonous substance from one country to another. it must be stopped. if people of the world don't unite their efforts against acid rains, trees and fish will die and we will too.
