We live in a world where spiritual beliefs have influenced every aspect of society; in history, culture, politics, and daily life, and traveling is a way to experience it firsthand and learn.
At Cooperating Volunteers, we carry out different volunteering experiences all over the world, and each country has its own culture, traditions, and way of life. That’s why this international volunteering experience is a purposeful and immersive journey.
Today we want to talk to you about some of the religions that exist in the world and how they have influenced in different ways depending on where they are practiced.

Did you know it is estimated that there are more than 4,000 different religions?
The exact number of religions in the world may vary depending on how they are defined and classified. The main or most practiced ones are: Christianity, Islam, Hinduism, Buddhism, Judaism, Sikhism, Taoism, Confucianism, Jainism, Bahá’í Faith, Zoroastrianism, and Shintoism.
Had you heard of all of them?
There are also indigenous and traditional religions, of which there are thousands, as they are specific to certain cultures, tribes, or animist religions of Africa, the Americas, and Oceania.
And on the other hand, there are hundreds of new movements, sects, and modern spiritual currents (for example, Scientology, Raelism, Wicca, among many others).
Many of them are not well known and therefore not as much information is available, but today we’ll give you a brief overview of the main ones.
