The universe is a big place - dark and empty….. is

The universe is a big place - dark and empty…..
…but we are fortunate. This
is Earth – our living planet!
We share our beautiful planet with many
other living things….
…..and it belongs equally to all of us.
Millions of years ago, the pattern of oceans and
continents on Earth looked very different to now…..
…..and because of continued change, the pattern
will look very different in the future.
Not so long ago in Earth’s history, there
were no humans.
From the time the first humans appeared,
it took thousands of years for the world
population to reach 1 billion.
It then took just:
100 years to reach 2 billion people…..
23 years to reach 3 billion people…..
21 years to reach 4 billion people…..
and only
13 years to reach 5 billion people…..
Today there are well over
6 BILLION (6,000,000,000) PEOPLE
How has this happened?
Why has this happened?
What will happen next?
Our world is a living world.
Every day it changes.
Some of the changes are natural……
…..and some are caused by people.
Natural forces are at work shaping our planet………
…..and tourists come long distances just to see
a beautiful volcano glowing in the night sky.
Elsewhere, millions of
people choose to live
and work in these
dangerous locations.
Why are they there?
We know the Earth used to be covered by millions
of hectares of natural forest and grassland.
Today, these are gone or rapidly
disappearing…… does anyone care?
Many people wonder why geographers spend so much
of their time trying to understand how rivers work……
These people
know why!
Some natural events are fortunately very rare…….
… 2004, we remembered
why we need to understand
and plan for these rare
natural events!!
On our beautiful but complex planet, everything that
happens is linked to everything else. When we…..
• drop a piece of litter
• pour a chemical down the sink
• chop down a tree
• burn coal
• build a motorway
• catch some fish
• fertilise the fields
• drive to work or school
…..the planet knows.
Natural changes are replaced by
changes caused by…..
human actions!
Over six billion people living on Earth.
Does everyone have the same basic services?
The latest UN Human Development Report stated that:
the world’s 500 richest people own more
wealth than the world’s poorest 400 million!
However, we know that it would take just
£3 billion to provide clean water for the 50%
of the world that don’t currently have it.
Too much ?
In Europe we spend more than that each
year on perfume and after shave!!
We could all help to change that situation…..
Some of the differences between groups
of people around the world need to be
better understood and respected…..
… is the differences in appearance,
language, clothing, food and culture
that makes the world a fascinating place
to learn about.
Other differences may require action…..
We need to know and understand about
these differences and what we can do as
individuals to help make the world a better
place for everyone.
We need to be active and responsible
citizens – every one of us!
When there were fewer humans around, people
lived in the countryside and their whole lives
had a clear focus on the land….
…..but in 2007, a very important change happened.
For the first time ever, over 50% of all human
beings were living in towns and cities.
Life in the cities is very different.
Sometimes it is better….
….often it is not!
Change is also happening in our communities…..
Is it getting better? Is it getting worse?
The environment?
Our hospitals?
Our sports facilities?
Our shopping facilities?
Our housing?
If you could identify and shape the future changes in
your local area…..
…..what would you change?
At the global scale, does our planet have
enough resources for 6 billion people?
What about 9 billion people??
What about 12 billion people ???
Now is the time to ask some
serious questions…..
Where are those resources that we all need to live?
<<< Oil for example
[OIL = fuel, plastics, drugs, artificial fibres and much, much more]
66% in the Middle East and only 2% in W. Europe.
Is it important to know and understand this fact?
How fast are we using our resources? When will they run out?
Silver (needed for jewellery & catalytic converters) – 9 years
Antimony (needed for drugs) – 13 years
Uranium (needed for power stations) – 19 years
Tantalum (needed for mobile phones & camera lenses) – 20 years
Copper (needed for wire cables and coins) – 38 years
What will we do when all these resources are gone?
Will we have enough of these resources to last
your lifetime?
We all need to learn a lot more about …..
You can play your part by showing that…..
Geography is about the world we live in…..the ‘here and now’.
Geography is about how the world is changing…..
Geography is about your world and about my world…..
Geography is about the future of our world.
How can anyone live without it?
