It is still difficult to understand what the meaning of ecological footprint is. I also have to browse several site to understand it more:

Here is what I understand:
Human needs resources to live. But by living also, human produce waste. The amount natural resources needed by human to live and to recycle their waste is what ecological footprint means (as far as I understood).
I was only thinking about one person. But in a world level, it’s talking about all people in the world, and their need, and their waste.
This is big.
Okay, now I’ll reduce it into one country, Indonesia, where I live.
Cited from https://en.wikipedia.org/wiki/List_of_countries_by_ecological_footprint Indonesia’s population is 224.67 million. Indonesian need of resource to live and recycle their waste (ecological footprint) is 1.21 gha/pers, while Indonesia’s natural resource capacity to support it’s people live (biocapacity) is 1.35 ghs/pers. So, there are still 0.14 gha/pers remain. That means Indonesia still have surplus of resources to support the people.
But, it’s only a small number of surplus. We don’t know what will happen in the next ten or twenty years. And we human lives in one world. There are countries that already have deficit resources, according to the list. Moreover, human needs are constantly increased by a lot of changing like globalization. Is our one earth enough to support us?
This is one serious problem to think.
Have you heard the word before, “Ecological Footprint”? Do you understand it? Do you know your footprint or that of your country or continent?
I will like to introduce you to Ecological Footprint:
Conceived in 1990 by Mathis Wackernagel and William Rees at the University of British Columbia, the Ecological Footprint launched the broader Footprint movement, including the carbon Footprint, and is now widely used by scientists, businesses, governments, individuals and institutions working to monitor ecological resource use and advance sustainable development.
Ecological footprint is the amount of biologically productive land (land that is sufficiently fertile to accommodate forests or agriculture or fishing grounds– they do not include deserts, glaciers and open oceans) and water needed to supply the people in a particular country or area with renewable resources and to absorb and recycle the wastes and pollution produced by resource use. It is measured in million/global hectares.
