The Montreal Protocol and its subsequent amendments resulted in the
elimination of many ozone depleting substances. A link to the Montreal Protocol
can be found on the course Webliography. Identify three other “world”
agreements or agencies committed to helping the world’s resources (including
plants, animals, and abiotic resources, such as gold and water). Summarize
(paraphrase) benefits gained in detail and include links used.
2.
Since the implementation of the Montreal Protocol, developed countries have
decreased the amount of ozone destroying substances they use tremendously. A
link to the Montreal Protocol can be found on the course Webliography.
Reduction by the United States has been 97%. View the following two animations.
The first shows the ozone concentrations as they varied from July to December
2008; the second animation shows average concentrations of ozone over
Antarctica during October — during the Southern Hemisphere spring when the
ozone hole typically is at its maximum extent. The areas of least ozone are
shown by blue and purple.
A.How did ozone concentrations vary between the
Northern hemisphere and the Southern hemisphere during 2008?
B.
Explain why the size of the ozone hole centered over Antarctica has increased
over the past 30 years. What changes occurred since the implementation of the
Montreal Protocol? What did the Australian Olympic Committee do to protect the
athletes and visitors? (List at least 3 implementations at this time concerning
radiation and ozone.)
3.
The KYOTO Protocol (The United States is not a signatory) has established
guidelines for the reduction of these six greenhouse gases: carbon dioxide
(CO2), methane (CH4), nitrous oxide (N20), hydro fluorocarbons (HFCs), Per
fluorocarbons (PFCs), and sulphur hexafluoride (SF6).
Select
three of these substances and describe their chemistry in the atmosphere over a
selected country/region (your choice). Show a chemical reaction (formula) for
all three; include a written summary of biotic and abiotic changes possible in
that country. Include current references/links. Paraphrase or block a direct
quote! Assume that your country has implemented or will implement the Kyoto
Protocol.1.
