Natural resources = products that people can use from nature 

When will the natural resources run out?

No unlimited supply of resources

• Some are renewable: food and wood
  
• Some are non-renewable: gold and petroleum (aardolie)
  

Renewable natural resources

Non-renewable natural resources

Wood

Petroleum

Coal 

Food

Gold

Carrying capacity = the Earth's ability to support all people's lives

Help!

With all the world's citizens together, we are using so many natural resources that we are exceeding the carrying capacity of the Earth

Carrying capacity 

• Only 1.8 hectares are available for each world citizen
  
• World Overshoot Day: the day that we have consumed what the Earth can produce on an annual basis 

Ecological footprint

• The amount of land a person needs to live their live 
  
• In The Netherlands we use 6(!) hectares per person

World population

Population projection: by the year 2100 there will be 11 billion of us on the planet

Not only population growth, but also...

Growing prosperity and  changing lifestyle lead to a larger ecological footprint 

Population projections means....

1. how many people live on earth (nowadays)
2. how many people used to live on earth
3. the predictions about the future population
4. the development of the population in the past

We need to be sustainable with what we have!

Dan kunnen onze toekomstige generaties ook gebruik van maken!

'Sustainable': what do you think about?

Sustainable: 

We do not use the natural resources on Earth faster than that they are replaced

Sustainable

Sustainable

Not sustainable
