Air Pollution. Air Pollution: Primary Geography
Australia has a relatively small population of 23 million people, yet we are putting millions of tonnes of greenhouse gases into the atmosphere. Each day all over the world Carbon dioxide is released when fuel such as wood, coal, gas and oil are burned. Carbon dioxide is also released from factories when coal is burned to make electricity and from our motor vehicles.
Carbon dioxide, methane and nitrous oxide, all greenhouse gases, have increased in recent years, causing our atmosphere to retain too much heat, which is turn has created global warming which is the increase of the earths temperature.
Greenhouse gases occur when we burn fossil fuels and can also be found naturally in our atmosphere.
These damaging toxins otherwise known as emissions can be harmful to the health and comfort of humans and animals, also harming the earths plant life and natural materials.
So lets break it down ……
All around the world there are beautiful blue skies and lushes green parks and flourishing farms. But with the rising levels of air pollution, overtime these beautiful aspects of nature will be damaged for future generations.
Natural and human sources are the two main causes air pollution in our world.
Smoke from fires, volcanoes, dust and methane all produce harmful emissions and are known as Natural sources of air pollution.
Power plants, factories, cigarette smoke, motor vehicles, aerosol cans and fire places are just some of the many Human sources that are used and operated on large scales in our daily lives, letting off harmful emissions into the air.
“What are our leaders doing to help?”
The current Australian Government have plans set up in order to ensure clean energy for the future of Australia. But don’t forget – Air pollution is not only occurring in Australia but ALL over the world.
To encourage Australia’s to use renewable resources the Australian Government has introduced a Renewable Energy Target scheme. This is designed to reduce emissions of greenhouse gases and encourage the additional generation of electricity from sustainable and renewable sources.
In the long run ensuring that 20 per cent of Australia’s electricity comes from renewable sources by 2020.
So what is renewable energy?
Renewable energy comes in the forms of wind power, solar power, waste to energy, bioenergy, biofuels and ocean energy. These sources are know as renewable and are a much “cleaner” option for our atmosphere. They involve recycling energy in order to create more.
Let us give you an example. (BIG PICTURE OF COW POO)
Cow manure can be used as a source of heat or electricity. This is done by collecting the cow manure from the farm, then using machinery to separate the methane that is naturally found in the manure and the solids and liquids that are left over. The methane can then be used to create heat and electricity back to the farms, and the liquids and solids can be used as fertilizer for the fields.
So what are YOU going to do to make a difference……
Walking to school, riding your bike, Catching public transport or car-pooling can all help to reduce the amount of fumes being released
Consuming locally produced products that are made or grown close to home will reduce the energy used to transport products from overseas countries
How can you help create a cleaner future?
