Transcript of Year 10 Geography: Air Quality

Air quality in Sydney is a serious issue.
Our group of geographers have successfully put together a solution to Sydney's air quality.
Task
Issues
Genetically modified trees with a greater capacity to intake greenhouse gases and release oxygen as well as the ability to release trace amounts of gases containing bacteria to target specific pollutants in the air, causing no harm to humans or any other animals
Solutions

Year 10 Geography: Air Quality
The air is over polluted because there are increased levels of industrialisation such as cars, factories etc.
Geographical Process that affect Air Quality
Air quality in Sydney is mainly affected by human activity, however Geographical processes also influence the quality of the air. The location of Sydney next to the coast means that large amounts of sea salt are in the air over the city. Also, coastal winds blow smog away which can be a positive influence on air quality. Dust being stirred up into the air by coastal winds is also a geographical process influencing air quality.
Human processes are the greater influence on air quality with fuels released from cars, substances released from factories and power stations having huge negative effects on the air quality of Sydney
Sustainability
Monitoring Air Quality
Trees live for hundreds of years, far longer than humans. Chopping down genetically modified trees can be prohibited to prevent numbers from falling. This would mean that the trees spread freely. Special areas for these trees can be allocated to contain them and concentrate the modified trees in areas of Sydney where they are most needed.
Install a Size Selective Inlet (SST) to detect extremely fine particles in the air over Sydney. Once the chemicals have been collected, they are analyzed. Data is compiled monthly to build up a database and monitor Sydney's air quality.
Bigger Problems and Past Decisions
Examples from other cities
In most countries, airports are exempt from air quality monitoring. However, airports are one of the biggest contributors to Sydney's poor air quality. Most of Sydney's air pollution is in the industrial areas such as the CBD. The EPA has set particle standards to be followed in populated areas in the National Environment Protection Measure (Ambient Air Quality). The EPA also monitor the particles in the air and research them with funding from their stakeholders. Once they find out what is required to kill the chemical they find out if it is possible to do so without creating hazards for human and other animals.
Since our idea is very unique it is hard to borrow ideas from other countries. However, the techniques that they are using could also be applied to Sydney because some of the sources of pollution are the same. In Europe, a vehicle called the Euro Vehicle has been designed and only emits extremely fine particles as opposed to normal cars which are contributing greatly to the smog.
