The Equation


‘Colombia has proposed to collaborate with Brasil and Venezuela in creating the world’s largest ecological corridor, spanning 1 350 000 km2 of rainforest’. (1)

The selected urban areas (2) and countries (3) below cover an area similar (4) with the suggested corridor in the Amazon. Together all these urban areas have a population equivalent (5) to the estimated population of entire India (6).

The 1/100 Equation (8)


The suggested Amazon corridor is approximately half the area of India (9), covering around 1/100th of Earth’s land area (10). The urban areas and countries above have a population equivalent to India (11).
2030 we will be 1,2 billion more people. (12)


In theory the Amazon corridor could house a billion people.

With this logic only, it would make sense to cut down the forest,

and start producing homes for the new born.


The effect of this would be less rainforest producing clean oxygen,

and absorbing carbon dioxide from the air. (13)

The people would have land and housing,

with quality of life affected by the lower amount of clean oxygen,

and impoverished soil, reducing the growth of nutrition.


Area A (Amazon) = ½ of area B (India) = 1/100th of area C (Earth) = areas X + Y (selected urban areas and countries) + Amount A (population in areas X + Y) = Amount B (population in area B) = 1,2 billion more people in 2030 + 805 million people starving today. (14)


If we protect the Amazon,

what 1/100th of Earth’s land area should be used for the next billion,

and how should we develop land for the 7,3 billion (15) already here?

Is the answer to the equation building more Mega Cities?


Instead of cutting down the rainforest,

I suggest an introduction of a Global Rainforest Tax,

treating Oxygen like a product as any other natural resource,

starting with the Amazon.




There are two great inventions on the market ready today:

The nanoFlowcell powers cars, trucks, ships and homes

with Saltwater. Saltwater.

Free from pollution.

‘Named after a Greek sea goddess, CETO offers the potential to revolutionise power and water production globally. CETO harnesses the enormous renewable energy present in our ocean’s waves and converts it into two of the most valuable commodities underpinning the sustainable growth of the planet: zero-emission electricity and zero-emission desalinated water.’


A Change to a Saltwater powered ground and ocean fleet,

would unleash the sustainable development globally,

solving the equation.


I am very optimistic

(13) ‘Rainforests are vital to the hydrologic cycle (rain and water systems), and they maintain some of the world’s most fragile soils. By absorbing carbon dioxide from the air, storing the carbon and giving us fresh, clean oxygen, tropical forests act as the world’s thermostat, regulating temperatures and weather patterns.’
