Did you know today is a special day? Well I had no idea until I saw one YouTube video.
The answer lies literally in the date and year. Yes, today 3/14/(20)15 is “The Pi Day”, not the one you eat (pie) but the one (π) you used in math class to calculate circles, and it seems that some math geeks get excited every 100 year (3.1415).
When I thought about 100 years from now, however, what came to mind were, “Will the mother earth still exist?” “Will human beings still be there?” and “What will it look like?”

What do you think about it?

First of all, it is difficult to predict what will happen in the future, let alone for another 100 years in this constantly changing world. But as for now, here are some projections with regard to what year 2100 might look like (link):

• By 2100, 80 percent of the world’s populations will live in cities
• The world will have a few hundred languages at the most, as opposed to over 7,000 languages right now.
• The world population (currently 7 billion) could be as many as 16 billion or 6 billion, depending on how the world controls the population.
• The percentage of over-65-year-old population will increase to 22.3 percent (from 7.6% in 2010)

In conclusion, more and more elder people who speak relatively common languages will live in the cities, which means there would be less diversity in the world.

But those are some data for human beings. When taking into account other issues like animals, global environment, energy source and possible technologies, we have no idea what the future holds (there are many different projections depending on two sides: optimistic or pessimistic ones).

Actually, given the large amount of damage that human beings have done on the planet, I understand the pessimists’ side. But I personally believe in the conscience and intelligence of human beings, therefore I am hoping that we protect the nature and humans with innovate ideas, like this TED talk of Japanese toy maker (English subtitle available). And it’s a little bit sad that I will not be able to see what 2100 will look like, unless I break the Guinness World record of long life. All I can do is to contribute to make a better world even on a tiny tiny tiny scale (I am working on figuring out how).

Let me finish this with the video of Pi about which I mentioned at the beginning of this post.
To make a change, it needs a lot of work, but it all starts from small steps. This video reminds me of this kind of thing. I hope we can make good steps for our future generations so that they can celebrate peacefully “The Pi Day” many more times (2115, 2215, 2315…).
