OUR PLANET's FUTURE
 

"images of a changing world"

by CBBC


WATER
Within 25 years, half the world's population could have
trouble finding enough fresh water for drinking and irrigation.



POPULATION
In the next 10 years about 800 million people 
will be added to the global population.



FOOD
Food production will have to nearly double 
to meet the demands of this growth.


CITIES
At the beginning of the last century, only one
in 10 people lived in cities. 
Now it's close to 50% - and it's still rising.


POLLUTION
Half the world's urban residents are exposed
to potentially harmful amounts of sulphur dioxide,
ozone and particulate matter in "smogs".


BIODIVERSITY
Every year thousands of species become extinct due to 
human activity and the loss of natural habitat.


FORESTRY
Logging and land conversion to accommodate human 
demand has shrunk the world's forests by half.



WETLAND
Urban and industrial development claimed 
half the world's wetlands in the 20th Century


REFUGEES
By 2025, the number of refugees fleeing floods and 
natural disasters could quadruple to 100 million.

 
ENERGY
For global development to be both fair and
sustainable, the rich world may need to cut
energy and resource use by 90% by 2050.


TRANSPORT
In the last 20 years there has been a two-thirds
increase in global household energy use, road vehicle
fleets have doubled, and air traffic has quadrupled.



WASTE
As population, consumption and wealth increase,
so does the quantity of waste we produce.
The rich countries of the OECD produce an annual
total of almost two tonnes of waste for every person.
