Poster by a student from Garneau School,
Edmonton, Alberta.
The blanket of air around the earth called the
atmosphere is full of water.
Most of the water moisture is in the form of an invisible
gas called water
vapour. If it is cooled it forms small droplets called
clouds, rain, mist or fog.
When the water vapour in the air mixes with gases from
factories, or car
exhausts, the water vapour dissolves and become acidic.
Sulphur dioxide
is created by power plants and metal smelters. Nitrogen
oxide comes from the exhaust of cars. These gases
when mixed in the air cause acid rain
which can harm trees, and interfers with how plants grow.
Fish that are exposed to acid rain cannot get oxygen properly
in their gills. The may not lay eggs.
: Drive less, walk,
cycle or share rides.
Use alternative sources of energy like solar or wind.
Turn off a light.
Use electrical appliances with conservation in mind.
Love and care for the water.
