1. Is it more effective to reduce Per Capita Consumption?
Part C
Is it more effective to reduce
Population, or
Per Capita Consumption?

2. If a = b = 2, then 10 X b is bigger BUT if a = 2 billion, and b = 2,
In C20th population increased X 5 and consumption X 10.
Which was more important?
Which is bigger: 5 X a OR X b ?
It all depends on the values of a and b
If a = b = 2, then 10 X b is bigger
BUT if a = 2 billion, and b = 2,
then 5 X a is bigger
ANSWER: Population, which started at ~ 1.2 billion and went to 6 billion. Consumption was modest initially.

3. What about recycling?
In the UK, up to 80 lifetimes of responsible recycling is completely cancelled out by the arrival of one more person via the airport or maternity ward.

5. Other points of comparison
A theoretical person has zero consumption when compared to any actual person.
If we cut consumption in any area, savings are often spent on other things, e.g. travel, so no net gain may be made.
If we share income with other people or causes, total environmental impact remains unchanged.
While using renewables may reduce per capita fossil fuel consumption, we need to check out the EROEI of renewables (i.e. check the maths). In some cases it is negative.

10. ‘These laws are not mere words …they are your life!’
Summary
To counterbalance the impacts of BETTER MEDICAL CARE and IMPROVED LIVING STANDARDS, we need to first stabilise, then reduce global population in order to combat global warming and tackle biodiversity loss.
This is a response which demonstrates gratitude for both the gift of better medical care and that of higher living standards.
‘These laws are not mere words …they are your life!’
(Deuteronomy 32:47)
