Once these puzzles are solved, we may have finally proved that aliens exist - or got one step closer to discovering that humanity is the only lifeform in the universe.

Of course, we won't know whether extraterrestrials are real until they get in touch with us or we find evidence of their existence.

And even if we do find alien life, it might be in the form of bacteria or other microorganisms, rather than fully fledged intelligent beings.

We have all over-used the planet. The result is too much CO2 in the atmosphere. This is leading to Global Warming. So the climate needs fixing.

The need to limit Global Warming to 2°C was agreed by World leaders in December 2015. But the action is too slow. We must act now.

The effects of Climate Change are already with us and getting worse – CO2 is now over 400ppm and needs to be less than 350 ppm in order to achieve between 1.5 and 2°C.

We simply cannot continue to keep doing what we are doing now. Climate Change may become irreversible if we do not act fast and on a massive scale.

The situation is urgent. We must stop adding greenhouse gases to the atmosphere.

That is possible because what we do now will determine who you will be in the future. The same goes for what you use now will affect on how you become in the future. If you are always sitting and playing/watching in your smartphone, you won't have time to exercise and will result to obesity. You have to always consider moderation in everything.

Alcohol and Drug abuse that ends up in Violence
Early Pregnancy resulting to Early/Single Parenting
Obesity because everything is digital now
and Poverty because if your family has low income, food comes first than education. If you didn't attend school, you probably can't find a regular job that pays you enough to no cause a problem.

Yes, definitely. I believe that He exists and He created Heaven ad Earth. I believe that He is just and fair as it was written in the Bible. I believe all this because I have experienced His love unconditionally. God has been showing me grace and mercy. He comforted me when I was weak and with no hope.

As a barometer of healthy money, the world’s best economies have average annual inflation rates below 1.5%.

In economic terms, low to zero inflation is a sign of healthy money because the value of the currency does not fluctuate significantly and is therefore reliable. However, in a country like Argentina, the annual inflation rate is estimated to be close to 40% today.

That means if you’re an Argentinian citizen and you save 100 Argentine Pesos, one year from now the value of those 100 pesos will be worth only 60 pesos relative to the world’s stable currencies. In Argentina, holding money means losing money, and so its citizens are actively looking for alternative stores of value to simply preserve the money they have earned and worked for.

Other examples of problematic economies with high inflation rates are Venezuela, which is expected to have annual inflation of 180% in 2015, and Zimbabwe, where the rate of inflation for the Zimbabwean Dollar was so high that this year they decided to stop printing it and the government is abandoning their currency altogether.

Zimbabwe went through a period of what is known as hyperinflation; their annual inflation rate in 2008 was recorded as high as 11,000,000%. What currencies could citizens from these countries use if not their own? The US dollar? Gold? M-Pesa? Bitcoin?

The reasons for such high inflation rates are complicated and they vary from country to country, but a common theme is that these rates are only found in government-backed fiat currencies.

Governments can lose control of their money in various ways because as with all fiat currencies, their values are tied to the laws of supply and demand. If a government prints too much money then the value of its currency can deteriorate, as seen recently in Zimbabwe, and after WWI in Weimar Germany.

History is full of stories underscored by the failures of money, and if history repeats itself, the future will be no different.

Given bouts of high volatility in bitcoin, it may be difficult to understand how this new Internet currency can act as a store of value. However, comparing the rate of fluctuation of the price of bitcoin to some of the fiat currency examples above, bitcoin contends as a candidate for an alternative currency.

Part of its appeal in countries with strict currency controls is the relative ease in which it can be acquired and used, especially considering all one needs is an Internet connection. Once money is converted into bitcoin, the inflation rates of local fiat currencies do not affect bitcoin holdings and it can be sent anywhere through the Internet for free.

Additionally, no one but the account owner has access to their bitcoin. This is especially important in light of the financial crisis.

In 2013, banks in Cyprus became insolvent but were bailed out by European and international monetary authorities. However, one of the conditions for Cyprus to receive the emergency funding was that bank depositors had to pay part of the tab.

That meant depositors, those who had their money in the banks for safe-keeping, found their individual accounts drained 6–10% by the government, overnight. That would be impossible with digital currency like bitcoin, which makes it valuable for many who reside in parts of the world with deteriorating economies and/or currencies.

Bitcoin also provides an option for those living in countries whose currencies are restricted or not free floating (eg China, Russia), looking to get money out of the country.

Even in the strongest economies the question of how stable certain fiat currencies really are is being tested. In a post-Great Recession world, governments of some of the leading economies decided to essentially print their way back to prosperity in one of the most massive economic experiments ever conducted: Quantitative Easing (QE).

The US led the way with QE in November 2008 with Ben Bernanke, then the head of the Federal Reserve, spearheading the experiment.

After Lehman Brothers collapsed, as the economic debacle unfolded, developed-market central banks became fearful of deflation as opposed to inflation, an experience Japan had been dealing with since the early 1990s.

Deflation is an insidious economic plague where citizens choose to hoard rather than to spend money, expecting lower prices for goods and services tomorrow relative to today.

However, an economy can only improve when its citizens spend money. When companies have too few customers because the masses are scared to spend, employees are laid off in order to cut costs, and unemployment rises, reducing income streams and thus spending power.

It’s a vicious downward spiral, and Mr. Bernanke decided that the best way to stimulate the economy would be to increase inflation and lower unemployment, and he aimed to achieve this through massively increasing the money supply of the US dollar.

The US printed trillions of newly minted dollars over the six year period from 2008 to 2014 in an effort to stimulate the economy. The program worked to a degree, inflating asset prices per design due in part to the US dollar representing the world’s strongest economy as the global reserve currency.

The European Union (EU) has seen the success of QE in the US and has launched its own program to try to aid their unstable economy. The EU will print over 1 trillion new Euros by the time their version of QE is over.

Whether QE works in the long run remains to be seen, but the fact is governments have the power to print as much of their own money as they want. If QE does not work and inflation becomes rampant, there are severe economic consequences as history has shown us.
