I will always be amazed by the creativity of some projects on the Internet and also by the fact that these projects do work! One of them is freerice.com and the idea is quite simple:

FreeRice has two goals:

1. Provide English vocabulary to everyone for free.
2. Help end world hunger by providing rice to hungry people for free.

This is made possible by the sponsors who advertise on this site.

Whether you are CEO of a large corporation or a street child in a poor country, improving your vocabulary can improve your life. It is a great investment in yourself.

Perhaps even greater is the investment your donated rice makes in hungry human beings, enabling them to function and be productive. Somewhere in the world, a person is eating rice that you helped provide. Thank you.

So it’s fairly simple, you have the main page where you try to find the meaning of certain words and for every correct answer, you donate 20 grains of rice through the UN World Food Program. So why don’t they just give all the rice now? Well, advertisers on the website pay for the rice, so these advertisers need a certain form of exposure. The vocabulary thing is just a way of keeping you on the website so you are exposed to more ads!

Anyway, this is a creative way of helping the world from the comfort of your home so give it a try!
