The ecological footprint measure

# data[].attributes.body
b (ii.)
As shown in the graph, as the stage of the demographic transition model increases, the ecological footprint increases. This is because the  higher stage of the demographic transition model is associated with increasing GDP per capita, with higher GDP, people are on average able to consume more and afford more things, thus increasing their ecological footprint.

The demographic transition consists of several stages:

Pre-industrial stage: high death rates and high birth rates

Transitional stage: death rates fall due to rising food production and better medical care. Birth rates remain high, so population surges.

Industrial stage: birth rates fall, as women are employed and as children become less economically useful in an urban setting. Population growth rate declines.

Post-industrial stage: birth and death rates remain low and stable; society enjoys fruits of industrialization without threat of runaway population growth.

b (iii) We agree with the statement that vegetarians on average have a smaller ecological foot print because this reduces the meat production.

Ecological Footprint is the amount of resources one as an individual uses among a community.  It is calulated by looking at the shelter, food, and amount of natural resources we use.

b) (i) Ecological footprint measures the amount of land that is required to provide human beings the resources that they need to consume over a given period of time (a year)

(ii) Generally, the higher the ecological footprint, the higher the stage of demographic transition

(iii) Their EF is smaller because they only EAT PLANTS and they are part of the lower trophic levels.

c) Less waste is produced as resources are reused

# data[].attributes.body
(i) EF is calculated through measuring the amount of resources that we use and how much energy it is required to produce to meet our requirements.

(ii) The ecological footprint grows as a i.e. country goes through urbanization. That is becuase demands grow on transportation, food, buildings, clothes (fashion), electricity.

b(I) How to calculate EF?

- Measures the amount of land and water used by an individual, a city, a country, a region, or all of humanity uses to produce the resources it consumes and to absorb the waste it generates with today's technology and resource management practices.

b(ii) relationship of EF and stage of demographic transition

Demographic transition is the model of economic and cultural change to explain declining death rates, declining birth rates, and rising life expectancies in Western nations as they became industrialized. The demographic transition consists with various stages, they are  Pre-industrial stage,  Transitional stage,  Industrial stage,  Post-industrial stage . The relationship between the ecological footprint and demographical transition is

b(iii) Vegetarians have a smaller EF?

- They don't consume meat. Meat production requires to use much water to grow plants to feed the animals, and to give them drink. Crops to feed animals also use land. Therefore, someone who eat meat has a much larger footprint than a vegetarian.

(c) How recycling reduce EF?

Waste absorption is part of EF. Landfill especially take large amount of land. Recycling allows to spare this land.
