Water Stress: A Global Problem That’s Getting Worse
Summary
TLDRThe script addresses the critical issue of global water scarcity despite Earth's abundant water resources. It highlights that 97.5% of Earth's water is undrinkable sea water, while fresh water is under pressure due to rising populations and temperatures. Companies like Coca-Cola, Pepsi, and Nestle contribute to pollution, exacerbating the crisis. UNICEF reports over 1.42 billion people, including 450 million children, face high water vulnerability, with regions like Eastern and Southern Africa and South Asia severely affected. Latin America, despite its rainfall, struggles with contaminated water, affecting countries like Guatemala, Honduras, and Peru. The script emphasizes the importance of clean, accessible fresh water and the challenges many face in securing it.

How could climate change affect water availability in Mexico City by 2050?
-Researchers estimate that natural water availability for Mexico City could fall by 10 to 17% by 2050 due to rising temperatures, exacerbating the existing intermittent supply issues.
Where is most of the world's freshwater located, and how does this affect global water distribution?
-Half of the world's freshwater is found in only six countries, which affects global water distribution and highlights the inequity in access to safe, clean water for over a billion people.

💧 Importance of Water for Life
Water is essential for sustaining life on Earth. Humans and all living things rely on it for hydration, cooling, and sanitation. Water plays a crucial role in keeping ecosystems alive and even in technical applications like cooling nuclear reactors. Despite its abundance, with 70% of the Earth's surface covered in water, there is a potential for a water shortage, as most of it is saltwater and not suitable for human consumption.
🌊 Fresh Water Under Pressure
Only 2.5% of the Earth's water is freshwater, and it's under increasing pressure due to rising populations and temperatures. Many major companies, including Coca-Cola, Pepsi, and Nestlé, are contributing to water pollution. A study by the Break Free from Plastic Movement identified these companies as top polluters across 42 countries. Over 187,000 pieces of plastic waste were collected, showing the extensive pollution caused by single-use plastics.
🚰 Water Vulnerability Across the Globe
UNICEF reports that over 1.42 billion people, including 450 million children, live in areas with high or extreme water vulnerability. In regions like eastern and southern Africa, more than 135 million children are affected. South Asia also faces severe water access challenges, with India having the highest number of children (112 million) struggling to get sufficient water. Ethiopia and Afghanistan are also severely impacted, with Afghanistan having the highest percentage of affected children at 93%.
🌍 Latin America's Water Crisis
Latin America, home to some of the world's largest rivers and lakes, still faces a severe water crisis. Despite receiving abundant rainfall, many of its water resources are contaminated. Countries like Guatemala, Honduras, and Peru suffer the most from a lack of clean drinking water. In Guatemala, 90% of the water is contaminated, while Honduras and Peru also have severely polluted water, with Peru's being contaminated with metals and toxins, possibly due to local mining activities.
💧 Water Crisis in Mexico
Mexico is currently experiencing a significant water crisis due to low rainfall, especially around Mexico City. The reservoirs and aquifers are severely depleted, with the capital's water supply reservoirs at only 49% capacity. Climate change is expected to worsen this situation, with natural water availability potentially dropping by 10-17% by 2050. Millions already experience intermittent water supply, and the situation is likely to deteriorate.
🌐 The Global Water Challenge
Although Earth may never run out of water, clean freshwater is not always available where and when it’s needed. Half of the world's freshwater is found in just six countries, leaving more than a billion people without access to safe, clean water. This highlights the global inequality in water distribution and the challenges faced by many regions in securing reliable access to this vital resource.

Transcripts
we all know water is one of the most
basic things
humans and all living things need to
sustain life
we use water to hydrate ourselves wash
and cool down
water is used to keep our lungs green
crops growing in nuclear reactors cool
but what would happen if we suddenly run
out of water
given that 70 of the earth's surface is
water and that volume remains constant
how is the water shortage even possible
well 97.5 percent is sea water unfit for
human consumption
and both populations and temperatures
are ever rising
meaning that the fresh water we do have
is under severe pressure
there are some companies that pollute
the waters coca-cola
pepsi and nestle are some
a report from the break free from
plastic movement identified that these
were the companies that most polluted
the seas and bodies of water after more
than 200 cleanings and brand outlets in
42 countries and six continents
in total more than 187 thousand pieces
of plastic garbage were outdated
identifying thousands of brands whose
main packaging is single-use plastic
that pollute oceans and rivers
according to a new report by unicef more
than 1.42 billion people
including 450 million children are
living in areas with high or extremely
high water vulnerability
eastern and southern africa with 58 of
children or more than 135 million south
asia with the greatest number of
children
155 million for 25
facing difficulty accessing sufficient
water daily
now seeing this on a country level india
has by far the highest number of
children facing high or extremely high
water vulnerability with nearly 112
million followed by ethiopia with almost
41 million
afghanistan has the highest percentage
with 93 percent
these countries are among the reports
list of 37 hot spot countries
on the other hand latin america is home
to some of the world's largest rivers
and lakes
the region gets more rainfall than most
other places around the globe
so is latin america suffering a major
water crisis
the answer is yes most of its water is
contaminated and not fit to drink
guatemala honduras and peru are three of
the latin american countries that suffer
most from a lack of clean water
approximately ninety percent of the
water in guatemala is contaminated in
honduras the water that is accessible is
dirty and filled with bacteria
the majority of peru's natural water
resources are polluted with metals and
harmful toxins
unfortunately no one is really sure why
but many assume it is because of local
mining and sea water enough
mexico is currently facing a crisis of
water due to an unusual low rainfall
around mexico city that has left
aquifers and reservoirs depleted
reservoirs in the kutza mala system
which provide one quarter of the
capital's water are at 49
capacity this year well below average
according to the water regulator
climate change could make the situation
worse researchers have estimated natural
water availability for the city could
fall by 10 to 17
by 2050 as temperatures rise
millions already suffer from
intermittent supply
[Music]
while our planet as a whole may never
run out of water it is important to
remember that clean fresh water is not
always available
where and when humans need it
in fact half of the words fresh water
can be found in only six countries
more than a billion people live without
enough safe clean water
[Applause]
