Internal Assessment

<ul>
	<li>Doubled from 1804 to 1922 (118 years)</li>
	<li>Doubled again from 1922 to 1959 (37 years)</li>
	<li>And then again from 1959 to 1974 (15 years)</li>
</ul>

🎈Fact Fun: The time taken for the population to double has decreased, but growth has cooled since 1999.

<ul>
	<li>It&#39;s called Exponential Growth.</li>
	<li>Imagine if the number of pizza slices you ordered doubled every time! 🍕&rarr;🍕🍕&rarr;🍕🍕🍕🍕... Yum, but overwhelming!</li>
</ul>

<ul>
	<li>Up to 95% of this growth is in LEDCs (Less Economically Developed Countries).</li>
	<li>Real-World Example: Many countries in Africa and parts of Asia are experiencing rapid population growth. Think of cities like Lagos, Nigeria or Dhaka, Bangladesh that are bursting with energy (and people)!</li>
</ul>

<ul>
	<li>We might peak at 9 billion but stabilize at 8.5 billion.</li>
	<li>By 2050:
	<ul>
		<li>High prediction: 11 billion</li>
		<li>Low prediction: 7.5 billion</li>
		<li>Medium prediction: 9 billion</li>
	</ul>
	</li>
	<li>FYI: The future&#39;s fuzzy. The further we peek, the cloudier it gets!</li>
</ul>

<ul>
	<li>Helps in planning &ndash; from sandwiches to schools! 🥪🏫</li>
	<li>Real-World Example: Knowing the future population can help governments decide how many schools, hospitals, or roads they need to build.</li>
</ul>

<ul>
	<li>Exponential growth means lots more resources!</li>
	<li>However, the twist: People in LEDCs might be increasing in number, but they consume fewer resources than their counterparts in MEDCs (More Economically Developed Countries).</li>
	<li>Real-World Example: A person in New York might consume more electricity, water, and luxury goods than someone living in a rural village in India.</li>
</ul>

<ul>
	<li>By 2075: approx 9 billion people.</li>
	<li>By 2100: Possibly three billion more hungry tummies!</li>
	<li>As people&#39;s wallets get heavier in developing countries, their plates get meatier! 🥩🍗</li>
	<li>Meat and dairy are top-tier foods in the food chain: they need more land and resources.</li>
	<li>Real-World Example: As China&#39;s middle class grew, so did their appetite for beef, resulting in a spike in beef imports and a greater carbon footprint.</li>
</ul>

<ul>
	<li>More people eating high up the food chain = more land, water, fossil fuels, and even your favorite avocado toast might get pricier! 🥑💔</li>
</ul>

In a Nutshell: Our world&#39;s population is growing at a breakneck pace, mainly in less wealthy countries. As our numbers rise and our tastes change, our planet&#39;s resources will feel the squeeze! We need to plan wisely for a balanced future. 🌍🤝🌱
