The stat showing that overweight people > under nourished people (although sad there are that many under nourished) is astounding.

Not any time in our history have more people been "over nourished" (i.e. overweight), than under nourished. Although, probably more unhealthy, it's still amazing how the majority of the world now doesn't have to worry about food on a daily basis (as opposed to most of human history).

Strictly speaking overweight and undernourished are not mutually exclusive categories

I hear this is a big problem in Brazil, where grains are cheap but everything else is expensive and hard to get. People get the choice between eating a normal amount and being malnourished, or eating a lot of carbs and getting proper nutrients but also becoming obese.

I all I eat is potato chips, I am both overweight and undernourished.

You should consider changing your diet

Have been scaring myself with this site since primary school, amazing to see it popping here!

Do we really only have 45 years of oil left?!

This is very hard to estimate -- 1) the oil companies may find new sources 2) they may find that existing beds aren't as productive as projected 3) extraction methods could improve 4) the rate at which we are using it could increase or decrease. And of course the question at any given time is not how much oil exists but how much is economically worthwhile for someone to extract.

But yes, the supply is certainly finite and between a few decades and a few centuries -- and while this seems like a small amount of time, it's not in comparison to how long it took for these deposits to form (tens to hundreds of millions of years).

Not only that, but to meet global warming goals of about 2C, we need to leave a lot of what is left in the ground. https://www.theguardian.com/environment/2015/jan/07/much-wor...

You have to keep in mind too that the flow of oil will start slowing down long before we get the last drop out. In fact it should start to slow down when about half of the total oil is extracted.

Hi, I have a doubt. You mention in your FAQ that these numbers are calculated from the estimates provided by WHO, IMF, World Bank and few other organizations.

My question is, from where is the data for TVs and Phones sold?, are these metrics from the reports by the mentioned organizations.

You can click each number to see which sources are used.

TVs numbers are from Display Search, which is the "worldwide leader in display market research". [0]

Phones numbers are from Gartner [1] & IDC Telecom and Networks [2].
