Internal Assessment

Main Idea: International efforts to reduce ozone-depleting substances, with the Montreal Protocol leading the charge.

<ul>
	<li>
	What: International agreement from 1987 focused on reducing emissions of ozone-depleting substances.
	</li>
	<li>
	Success Level: 🌟🌟🌟🌟🌟! By 2012, the world had eliminated 98% of these harmful chemicals.
	</li>
	<li>
	Participants: Almost like a global party! Nearly 200 governments jumped onboard.
	</li>
	<li>
	Updates: It&#39;s not static; it&#39;s evolved 7 times since its inception in 1987.

	🎉 Fun Fact: Think of the Montreal Protocol like your smartphone&#39;s software update. It keeps getting better with time!
	</li>
</ul>

<ul>
	<li>Ozone Recovery: If we keep this up, by 2050, our ozone could be back in its prime.</li>
	<li>Fast Action: Due to the Protocol&#39;s success, Europe achieved a phase-out by the year 2000! The global goal? 2030. That&#39;s some speedy environmental action!</li>
	<li>Boost in Innovation: Countries started thinking outside the box for alternatives.</li>
	<li>Awareness and Ed: More people now know about CFCs (not a cool band, but harmful chemicals).</li>
</ul>

🌱 Real World Example: It&#39;s like when we found out that plastic straws hurt turtles. We didn&#39;t just stop using them; we looked for eco-friendly alternatives!

<ul>
	<li>Tech Transfer: Higher income countries passing on tech to Less Economically Developed Countries (LEDCs) to help them switch from the bad stuff.</li>
</ul>

<ul>
	<li>Replacement Issues: The alternatives to CFCs, like HFCs, turned out to be potent greenhouse gases. Oops!</li>
	<li>Legacy Impact: Some of these chemicals have a long lifespan. So, the atmosphere will still face some harm, possibly up to 2100.
	<ul>
		<li>🤔 Real World Example: It&#39;s like cleaning up after a big party. Even if the party stops, the mess can remain for days.</li>
	</ul>
	</li>
	<li>LEDC Struggles: For LEDCs, the change is tougher.</li>
	<li>Old Appliances: Just because new ones are better doesn&#39;t mean old ones disappear. Some old fridges, still spewing the bad stuff, are out there.
	<ul>
		<li>🍔 Real World Example: Think of it like vintage fashion. Just because something is old, doesn&#39;t mean it&#39;s not in circulation!</li>
	</ul>
	</li>
	<li>It&#39;s a Team Effort: The Protocol&#39;s success rests on nations agreeing and sticking to it.</li>
</ul>

💡 In Summary: The Montreal Protocol is a shining beacon of hope for the environment, showing us that when the world comes together, we can make significant positive changes. Yet, while we&#39;ve made considerable progress, there are still challenges to overcome. The fight continues, but with teamwork and innovation, a healthy ozone layer is in sight!
