The population is expected to reach between 8 and 10.5 billion between the year 2040^[10][11] and 2050.^[12] In May 2011, the United Nations increased the medium variant projections to 9.3 billion for 2050 and 10.1 billion for 2100

What do you call that, @Antonio?

 

Why don't you cite the complete paragraph?

 

As of 2015^[update], the population of the world is projected to reach 8 billion in 2025, and 9 billion by about 2040/42.

 

Reasonable prediction of population development are possible for the next 30 years or so, representing the period of fertility of the children alive today. Projections of population reaching more than one generation into the future are highly speculative: Thus, the United Nations Department of Economic and Social Affairs report of 2004 projected the world population to peak at 9.22 billion in 2075 and then stabilise at a value close to 9 billion;^[19] By contrast, a 2014 projection by the United Nations Population Division predicts a population close to 11 billion by 2100 without any declining trend in the foreseeable future.^[20] On the other hand, a conservative scenario published in 2012 assumes that a maximum of 8 billion will be reached before 2040.^[21]

 

2 projections out of 3 predict a peak of 8-9 billion in this century (from current 7.3 billion). And the one that doesn't predict a peak, only predicts 11 billion by 2100 (only 50% increase with respect to today) and its claim of "without any declining trend in the foreseeable future" seems highly dubious, since the birth rate hasn't stopped decreasing since 1950 at least https://en.wikipedia...wiki/Birth_rate and last year's total fertility rate of 2.4 is so low that it's barely enough to guarantee survival of mankind https://www.youtube....h?v=I1hlLM-LTmU

I dont cite it, because you can read it from the link lol

 

Alright. Here you are the entire paragraph:

Overview[edit]

The human population has been growing continuously since the end of the Black Death, around the year 1350,^[3] although the most significant increase has been in the last 50 years, mainly due to medical advancements and increases in agricultural productivity. The rate of population growth has been declining since the 1980s. The United Nations has expressed concern on continued excessive population growth in sub-Saharan Africa.^[4] Recent research has demonstrated that those concerns are well grounded.^[5] As of December 17, 2015 the world's human population is estimated to be 7.29 billion by the United States Census Bureau,^[6] and over 7 billion by the United Nations.^[7][8][9] Most contemporary estimates for the carrying capacity of the Earth under existing conditions are between 4 billion and 16 billion. Depending on which estimate is used, human overpopulation may or may not have already occurred. Nevertheless, the rapid recent increase in human population is causing some concern. The population is expected to reach between 8 and 10.5 billion between the year 2040^[10][11] and 2050.^[12] In May 2011, the United Nations increased the medium variant projections to 9.3 billion for 2050 and 10.1 billion for 2100.

 

 

 

 

It doesnt change the fact, that the expectations are for overpopulation.

 

 

 

 

 

[Antonio2014]

I don't find there any proof of overpopulation, only concerns, that is, opinions. If you look at the facts, the opposite seems more realistic:

 

1) From your cite: "the rate of population growth has been declining since the 1980s".

 

2) World crude birth rates (per 1000) every 5 years, 1950-2010: 37.2, 35.3, 34.9, 33.4, 30.8, 28.4, 27.9, 27.3, 24.7, 22.5, 21.2, 20.3.

 

3) Year 2014 total fertility rate: 2.4.

 

4) See world hunger evolution here: http://www.fao.org/hunger/en/ Clearly, we aren't heading a food supply problem due to overpopulation. On the contrary, hunger has been diminishing for decades now.

 

Also, your cite contains its own rebuttal of the overpopulation concerns:

 

"Most contemporary estimates for the carrying capacity of the Earth under existing conditions are between 4 billion and 16 billion."

 

"although the most significant increase has been in the last 50 years, mainly due to medical advancements and increases in agricultural productivity"

 

Guess what carrying capacity depens on? Yeah, agricultural productivity and other technology advancements. We are now experiencing a second Green Revolution with GMO (the fastest growing agricultural sector in the world). Also we are seeing continuous improvements in clean energy production and use, materials recycling, clean and cheap manufacturing, etc.

The people say it clear enough. The expected number is 10.1 billion for the year 2100

[Antonio2014]

And more people say that it don't. And, anyway, that isn't overpopulation.

Lol don't sweat it.
Cancer is the bodies way of dealing with an over acidity, a cell goes rogue by many mechanisms, normal cells can be totally immune to it if there's nutrients from fresh foods, etc.
To use an analogy of Cancer to discribe a group of free living stereotypes is just dramatising dogma parroted from someother fear mongering ideologist.
Don't believe the hype?

People should go vegan. you will not only live longer, but also give a breath to the earth. Problem is people are ready to do anything to avoid to see the truth of what they love to eat.

 

No need for insect even. Im vegan since more than 10 years now, and im playing soccer every week. My blood result are perfect so far and i feel very good. The meat / dairy industry however make also everything to market their product or make people feel its good to take meat to be strong. Probleme is more and more study show vegan is better but also vegan athlete grow everywhere over the world. Not only carl lewis
