Issues
Now 8 billion compared to 3 billion in 1950s
9 billion by 2050
Demand for water
drinking water
production
hidden water
3000 liters to produce a burger
9000 litres to produce a chickenUK alone consumed 1 billion in 2012
27000 litres to produce 1kg of choccy
2700 per bar
100 litres to produce a cup of coffee
20 billion coffees in th UK in 2012
36 billionlitres of water used for plastci botttles in 2012
unusual drought and flooding
Incresaing CO2
result of agriculture, land use, porcessing, transportation
demand for food land is gonna double at least by 2050
presdsure to clear land from rainforests (the only land left)
1billion hectares by 2050 to be cleared to meet rising food demands

demand for land
by 2050 70% will be living in cities
rapid expansion of cities
19 brazillian cities have doubled form 2003-2013
need to produce more food than the output of the past 10 000 years combined

10 warmest years on record since 1998
rising sea temperatures
mining and pollution
pandemics
Spanish flu killed up to 100 million
millions now traelling and spreading disease across borders
virus jumps more likley
increasingly porbablility of a global pandemic (covid)
Need to triple energy production to meet demand
need to build
1800 of the world's largest dams
or 23 000 nucelar power station
14 million wind turbines
36 billion solar panels
or 3600 new oil and coal station with that limited resource
Climate change
future global temperature rise of 4-6 degrees C
likely lead to runaway clmiate change capable of tippingthe planet into an entirley different state rapidly
extreme weathers
fires
floods
heatwaves
loss of crops
loss of forest
water stress
sea elevel rise
