Poor environmental sustainability - Haze by Mind Map: Poor environmental sustainability - Haze

1. What: Haze is an atmospheric phenomenon where dust, smoke and other dry particles obscure the clarity of the sky.

2. Who: Sources for haze particles include farming (ploughing in dry weather), traffic, industry, and wildfires (forest fires)

3. Why: Haze is formed when dust, smoke and other dry particles obscure the clarity of the sky and they therefore mix together with dry air and haze is the end product of this

4. Where: Since 1991, haze has been a particularly acute problem in Southeast Asia

5. When: A recent haze was started by Indonesia a few weeks ago, and haze has been quite common in Southeast Asia, happening maybe once or twice a year

6. How: Haze often occurs when dust and smoke particles accumulate in relatively dry air. When weather conditions block the dispersal of smoke and other pollutants they concentrate and form a usually low-hanging shroud that impairs visibility and may become a respiratory health threat. Industrial pollution can result in dense haze, which is known as smog.

7. Whose: Haze forming because of dust, smoke and other dry particles may not necessarily be our fault by haze started by forest fires is an entirely different matter - we can decide it. It is our responsibility to sustain our environment to take measures to save our world and prevent it from further harm.
