For many people living in the Hawkesbury area, these activities are a weekend routine, however, people living in urban areas don't need to make this change to their lives because of the threat of bushfires.
When a bushfire burns it releases huge amounts of smoke and ash into the air above and surrounding it. This thick, heavy haze pollutes the air to a major extent, making it hard to breath in, settling on rooves and in gutters of homes with water tanks, and can even effect the operation of engines as their air intake is compromised. Also, pollution can be carried into many areas far from the actual blaze by the wind. This just multiplies the smoke affected area.
Bushfires are one of the most destructive natural disasters in the world, they destroy everything in their paths, most that lies in the...
