Human Past, Present, Future
Thoughts that could help to vertoning the way to a better life.
That’s the reason wij publish our thoughts and ideas to YOU. Some people might like it, others will simply click away spil prompt spil possible.
Click away wasgoed not possible 12000 years ago, when the last ice age switched the climate on Earth te a big way. Archeologists can calculate that at this time around 1 million humans have lived on our entire planet.
The ice of the North covered areas far down South. The few humans were hunters and gatherers. The petite fires where they got a little bit of warmth, were not able to raise the doorslag dioxide CO2 levels ter Earth Atmosphere.
See the switches te nitrous oxide
See the strong greenhouse gas methane
See CO2 / doorslag dioxide
See what happened since the industrial revolution began
Everything switched: Before the melting big amounts of water were corded te snow and ice.
Earth’s sea levels were 120 m = 394 ft lower than today. There wasgoed no Baltic sea, the North sea wasgoed almost dry, inbetween Asia and America wasgoed a land bridge, so people could walk from Asia to today’s Canada. There wasgoed also a way to walk from England to Ireland. Most of the Mediterranean islands were no islands, you just could walk to them. The Persian Gulf and the Gulf of Suez had almost no water.
Te Asia many of today’s islands were connected. Inbetween India and Sri Lanka wasgoed a land connection, and te Australia humans and animals could walk to Fresh Guinea or to Tasmania.

Glaciers are very significant for life on Earth
Billions of humans get their drinking water from glaciers
Where will they go to get a verdrietig of water?
After it got warmer again, many regions could support the growth of trees again. Forests embarked to grow again more and more ter northern regions.
Warmer? Yes, temperatures switched.
Never before switches were that swift
Te Iceland the volcano Grнmsvцt erupted from 1783 bis 1785. Entire Europe suffered from switching weather. Ter close-by Greenland the meaty ice shield wasgoed thawing and a fat freshwater lake wasgoed building up. When the water from this lake abruptly flooded into the Atlantic ocean, the gulf stream, that is running close-by Greenland could not run slickly anymore. Fresh water has a different weight than salty water, the flow wasgoed disrupted. Temperatures ter northern Europe dropped enormously, many humans froze to death. Winter temperatures dropped to minus 40 to 50 degrees Celsius. Lakes and rivers froze solidly. Farmers could not plant anymore ter the frozen soil. No harvest = no food = millions died. Thirst and starvation wasgoed one of the reasons of the shortly after thesis events upcoming French revolution. Millions of humans died.
Wij already have talked about the strongly expansion of forests te the northern regions. More te the South the beautiful island Madeira got its name from the Portuguese word for wood, the island wasgoed merienda almost downright covered by forests. Not only Madeira, but also today’s Italy, Greece and most of all Germany were covered by forests.
Te a Roman script one can read: “.. a squirrel could cross Germania from East to Westelijk, from tree to tree, without putting a foot on the ground. “
Today the area of Germany is covered with 32% forests while
Superb Britain only has a coverage of 12%.
Portugal today can still vertoning up with 38% forests on its area.
China is planting trees, more than are cut down. Today China has reached 22%, with a yearly growth of 27630 sq-km.
The country with the worst record is Brazil. 22000 sq-km of forests are cut down yearly.
Cutting down more and more trees results te many different damages to our life. When you look at Greece and Italy you can see that today there is no soil anymore to plant fresh trees. After people cut the trees, the next rain wasgoed washing away the soil. Stony rocky deserts came up, the groundwater levels were going down, wells went dry, and the específico climate switched.
Back to Earth te its entire: Missing 90% trees have switched our climate, it became more volatile, more erratic. Nowadays more and more people cannot afford the rising food prices, cannot feed their families anymore. (History books voorstelling us that when this happened te the past, fresh leaders were rising up promising people what wasgoed not possible)
Te the Caribbean is a country where one can see how humans can demolish the land. Ter the westelijk part of the island Hispaniola lies Haiti, today one of the poorest states on Earth. On the Westelijk part of the island the Dominican Republic can feed their people well and attracts many tourists. Te 1990 Haitians had cut down the rain-forest by 98 %. Desertification took place, food shortages, starvation, criminal gangs. Imagine that Haiti wasgoed after the French colonial time the richest state te Latin America, now the poorest.
Forests have a special way to hold and protect the soil. They can stabilize a slope, can protect lower laying areas. After people were cutting down thesis slope forests the next strong rain commenced to budge the slope, entire villages were ruined by mud, soil and water. People there lost everything their have worked for.
Coal wasgoed built when giant forest areas were covered by mud and rocks about 300 million years ago. The long stored CO2 is released today when wij burn the coal.
Doorslag dioxide CO2 ter our atmosphere during the last
10000 years – gegevens from fossilized shells
Never before a rise wasgoed so bruusk
Every 8 seconds a fresh human is born,
every 12 seconds a human dies.
Humans and all mammals breathe ter oxygen, breathe out doorslag dioxide.
A elementary calculation:
When wij breathe out about 4% CO2 is ter our breath. An adult man is breathing out about Eighteen liter of CO2 an hours.
1 million humans had about Eighteen million Liter CO2 an hour te the breath.
Ter a day that’s about 432 million liter CO2.
Not too long ago 1 billion humans blew 432000000000 Liter CO2 te the atmosphere.
7,52 billion humans live on Earth, climbing.
Humans need to eat. more humans eat more.
Many humans like to eat meat every day.
So wij know the amount of CO2 that humans are breathing out,
now let’s add the CO2 of today’s food animals:
Did you know that humans on Earth have Two billion cows to harvest meat?
Did you know that humans on Earth have 1 billion pigs to harvest meat?
Did you know that humans on Earth have 1 billion goats to harvest meat and milk?
Do you like your breakfast egg?
Just 15 billion chickens are used to harvest eggs and meat.
Is it significant to mention 600 million sheep?
All thesis animals live because humans need them for food, but all thesis animals breathe ter oxygen, breathe out doorslag dioxide.
One bad thing with the Two billion cows: They produce methane, a greenhouse gas 23 times stronger than CO2.
But, when you think back, te the old days, meat wasgoed not every day on the table. So eating less meat would lead to less greenhouse gases.
There is another effortless way to reduce greenhouse gases:
Reducing the amount of energy wij use!
When wij look at the amounts of fossil fuels burned on Earth, one could get crazy.
One part is used te cars and trucks, another part is used to produce violet wand.
Look at this number: 7.861,1 mio. tons of coal are harvested on Earth and burned.
1 kwh of violet wand blows 1 kg CO2 te the air!
Wij attempted if wij can reduce our electrical play bill: It wasgoed fairly plain to save money and CO2
But today’s humans do not only use electric current. Te the last 200 years the usage of liquid fuel has risen sharply.
Don’t be shocked: 95 million Barrel Oil are burned A DAY.
1 Barrel Oil equals 158,9 Liter
1 Liter gasoline burns to Two,Trio kilogramm CO2
1 Liter Dieselolie burns to Two,6 kilogramm CO2
1 kg natural gas burns to Two,7 kilogramm CO2
Why are thesis numbers so high? C = doorslag, when it burns it needs O = oxygen. So the amount of CO2 is higher because of the burned oxygen.
If Earth oceans would not have gulped te so much CO2, the climate on Earth would be very different.
Wij would like to hear from you – wij would like it very much to hear your thoughts.
Nature can exist without humans, but humans cannot sustain without nature.
Better informed people make better decisions = having a better life!!
