Week 8 [03.12-09.12.18] Outbreaks in nature don’t end well – How will we survive when the population hits 10 billion?


„Outbreaks in nature don’t end well” – How will we survive when the population hits 10 billion? 

Put a couple of a protozoa into a petri dish full of nutrient goo and leave them for some time. Without natural enemies, in perfect climate, they will eat and reproduce until they will hit the edge. In that moment they will start drowning in crowd and starving. Do the same fate awaits us?


Unstoppable demographic growth has just begun
The current world population of 7.6 billion is expected to reach 8.6 billion in 2030 and 10 billion in 2050. This is the only the beginning. Unstoppable demographic growth has just begun.  

Shifts in country population rankings
China is known as a the most populous country in the world, but in roughly seven years population of India is expected to surpass that of China. Due to higher population growth of India, margin between these two country is coming down quickly. Right now China and India together account 36.28% of total world population.

Ageing
Globally, population aged 60 or over is growing faster than all younger age groups. That means the number of persons aged 80 or over is projected to triple by 2050. By 2100 is expected to increased nearly seven times its value in 2017.
Don't forget about possible life extension in future.




My questions for you:
1. How are we going to provide everybody with basic needs while also avoiding the worst impacts of climate change?
2. Could our planet sustain that many people over the long-term? Could we sustain?
3. Have you generally agree with Charles? Or maybe are you closer to "wizards" or "prophets"?

About eighty percent of planet's population is already robbed of basic needs. In fact, never actually had known them. I think that there will be a lot of moral topics that require re-estimation for this specific situation. Hopefully by that time we will colonize Mars or other planets.

To quote Jared from Silicon Valley
"In the 1890s, the Industrial Revolution had people flocking to the city, and more people equals more horses, and more horses equals more manure. And it was predicted that by the middle of the next century, there would be nine feet of manure covering the streets. But what no one saw coming, was a new technology that would completely obliterate those concerns. The car. Over night, the manure problem vanished."
Here is the same problem that we don't know what might happen and what great inventions are right behind the conner.

It's not that easy to answer this question. I guess that countries which are already developed they won't suffer that much, however I can't say that about third world countries.

Yes, I think our planet can deal with that numbers, but humanity has to completely change the way how we live.

I guess I'm closer to 'wizards'.

1. How are we going to provide everybody with basic needs while also avoiding the worst impacts of climate change?

We're not going to. Sooner or later there won't be enough basic resources for everybody.

2. Could our planet sustain that many people over the long-term? Could we sustain?

Again, sooner or later we will exceed the capabilities of our species and our planet, as they are also limited.

3. Have you generally agree with Charles? Or maybe are you closer to "wizards" or "prophets"?

I'm am pretty agree with Charles, but I see no possible good future regarding the outbreak. We could avoid it, but we are not monolithic. The whole humanity is a patchwork. While on the one side of the planet the CEO signing the billion revenue contract, on the other side a bunch of tribal people are hunting animals with bows and arrows. While one half of the countries accepts progressivism and liberalism, trying tobuild some kind of future, the other half goes back to the traditionalism, literally going back in time for decades. We are not going to make it. We are doomed.
Generally, I don’t agree with Charles. In my opinion our planet can hold much more than 10 billions people, if one looks at population density map, may see that almost all people are concentrated in relatively small areas. There are vast amount of inhabited areas, but people tend to live in groups. Things like hunger and water supply shortage exists not because we cannot growth any more food anywhere, it is because in poor countries, the agriculture is also poor. It all depends on money and technology, population size doesn’t matter. For example, Delhi is megacity in India, with population over 16 million people. There are a lot of problems with the environment (https://en.wikipedia.org/wiki/Environmental_issues_in_Delhi) or poverty. On the other hand there is megacity like Tokyo. There are 13.506 million people in Tokyo with 9.214 million living within Tokyo's 23 wards, and yet there is no food shortages or environmental problems of huge scale.
What is more, if we would like to colonize space, huge population is almost necessary. There are probably at least 100 billion planets in the Milky Way (https://en.wikipedia.org/wiki/Milky_Way#cite_note-Nature-20120111-29), therefore 10 billion people is really nothing compared to this.

To be honest, I can't agree with him in 100% too. Generally, IMO his speech was just a warning for all of us. Ten billion is not an amount, which we should be scared. But, what we gonna do when world population will hit for example 18 billion?

Colonize space is only guesses and empty hopes for me. We have advanced technology, but in my opinion we are still really far away from that part of future.
Marcin Krupa said…
Ya, that's hilarious. We are overproducing food, but some part of the world are still starving to death.
1. How are we going to provide everybody with basic needs while also avoiding the worst impacts of climate change?
Unfortunately, I think that nothing will change in the future. At the moment, people can not provide all the basic needs. The rich will become richer, poorer poorer.

2. Could our planet sustain that many people over the long-term? Could we sustain?
I think that our planet is ready for this path :) But the people who live and use the Earth are not ready to unite to solve the problem before us.

3. Have you generally agree with Charles? Or maybe are you closer to "wizards" or "prophets"?
I definitely agree with the speaker. I am an optimist, I like the way the “wizard”, but I think that the technology of the “wizard” of the future will be available only to rich countries and “prophets” for poor countries.
I only partially agree with this journalist. Because first of all, our growth is not unstoppable. There are already scientists talking about humanity never hitting more than 10 billion. Even if you take a look at our own backyard - the number of Poles is shrinking, not growing. Of course this causes a different problem - aging of the population, but still - there is a limit to our growth.
Also, another good question is: how big is the perti dish? Is it our planet? Or maybe it's our solar system? We are not only expanding our numbers but we are also working on enlarging our petri dish. Of course, this is wizard thinking in me, we still don't have the technology to even permanently stay on the moon, but yes, we are getting there.
But I agree with the prophet's side as well - we have to change our behavior. How we use our resources, how we consume them. We need to be more environmentally friendly, or we will destroy the environment and ourselves in the process.
I think we can sustain our population but it will require us to work on that. So wizards and prophets have to work hand in hand, embrace the renewability and look optimistically at future. We'll survive. And I think we are special. Our minds make us special. So let's use them to find a good solution for future generations.
I think that this is bad thing that population of planet grow each year and in future this can cause huge problems to us because we need to produce enough eat and recycle all that has produced by our lifecycle.

I think what we has braked main nature humanity control mechanism when started to fight with illness and this is our mistake in general. In current time a lot of countries trying to increase population of people but as I know there another countries that trying to fight with such quick population growing on their territory but I think this restrictions must be bigger than now and we need to try control humanity population in earth scales.

I think If we just wanted to max out our production of food, we could probably feed 20-30 billion people.
Population goes down as we improve our medicine. Countries with better health a consequence of more education and income which leads people to decide to have less children instead of better health alone. And yet It’s crazy how many people want to eradicate entire chunks of population just because they think we are too many.

we need another plague

Yeah let’s start with you

Of course, we don't know what might happen in future, but I think that we should be prepared for the worst scenario. To be honest, I think that we will carry it off pretty easily, but I'm not sure.

By the way, accurate quote!

"I think If we just wanted to max out our production of food, we could probably feed 20-30 billion people."
Sure, but creating food is the least of our worries.

"eradicate entire chunks of population just because they think we are too many."
As I said, I'm not agree with Charles in 100%. Ba! Generally I think that he is hyperbolizing this topic. I just presented by his words possible disaster when our population will hit - for example - 25 billion.

"we need another plague"
There are tons of another good, humanitarian methods. We don't need to kill people to decrease population growth, lol.
Marcin Krupa said…
To be honest, I have very similar view to you. In my opinion, author is hyperbolizing this problem, but he pointed out possible difficulty for future generations.
Marcin Krupa said…
"I think what we has braked main nature humanity control mechanism when started to fight with illness and this is our mistake in general. "
To be honest, I can't agree with you. We can't stop enveloping medicine, because of some indirect not exactly bad after-effects.

Personally, I think that creating that type of restrictions are not a good idea. Acting like Chinese some years ego is no humanitarian. IMO, some country should stop promoting creating big families etc.
I am very afraid of the problem of overpopulation of the planet. I think the governments of countries need to reduce their ambitions and impose a limit on the number of children. Now the opposite is happening, people who refuse to bear children are condemned in society. Countries are thinking about their economic stability in the future, but they do not think that there will not be enough resources for everyone. I really hope that we will open the opportunity to live on other another planets. And it would be better for scientists to hurry, there is not much time left.

1. How are we going to provide everybody with basic needs while also avoiding the worst impacts of climate change?

It's really sad that the most poorest countries always have the most high birth rate. I think that nature will regulate the population of earth, and people cannot impact that.

2. Could our planet sustain that many people over the long-term? Could we sustain?

I think planet is ok, it's only people have problems.

3. Have you generally agree with Charles? Or maybe are you closer to "wizards" or "prophets"?

I agree with Charles, and I think that wizards and prophets have seeds of truth.

Week 11 [03-09.06.2019] The problem with ecological cars emission in UK

The problem with ecological cars emission in UK Since the adoption of the European Emission Allowance Directive in the European Parliament, all car makers have tried to submit. Since 1992, the Euro I standard has been in force, which limited the emission of carbon monoxide to the atmosphere. The Euro VI standard currently applies, which limits the series of exhaust gases. These include: hydrocarbons, nitrogen and carbon oxides, and dust.   The most significant change was brought by the Euro IV standard. For the first time it introduced the limitation of nitrogen oxides, which are responsible for the harmful compounds of smog.   What is smog?   Smog consists of sulfur oxides, nitrogen and carbon. In addition, solid substances such as suspended dust (PM). Dust suspend in atmospheric aerosols may be in liquid and solid form. These can be particles of sea salt, clouds from the Sahara and artificial compounds made by people. These compounds often come fr

Week 12 (12.01-18.01.15) Are you an early bird or a night owl ?

Owls are nocturnal creatures. They’re wide awake at night and they sleep during the day. If this sounds like bliss to you, then, like about 20 percent of the population who find themselves most active at around 9 pm, you may fall into the same category as our feathered friend. Night owls often have difficulty waking up in the morning, and like to be up late at night.  Studies of animal behaviour indicate that being a night owl may actually be built into some people’s genes. This would explain why those late-to-bed, late-to-rise people find it so difficult to change their behaviour. The trouble for night owls is that they just have to be at places such as work and school far too early. This is when the alarm clock becomes the night owl’s most important survival tool. Experts say that one way for a night owl to beat their dependence on their alarm clocks is to sleep with the curtains open. The Theory is that if they do so, the morning sunlight will awaken them gently and naturally.

Week 4 [06-12.11.2017] This is what happens when you reply to spam email.

James Veitch is a British comedian. In today’s Ted Talk James with characteristic for himself a sense of humor shows how he deals with spam emails and why responding to junk messages may be sometimes dangerous. Questions: What do you think about James’s  way of dealing with spam? Why are junk messages legal, even though it sometimes may be a fraud? Dou you have a problem with spam? How do you deal with with it?
