Nearly three million Muslims perform the Haj every year. The Haj pilgrimage, during which Muslims from around the world travel to Makkah in Saudi Arabia to perform religious rites, is considered to be one of the largest gatherings of people in the world. Allah says in the Quran: “Fulfill the pilgrimage and make the visitation for Allah. If you are prevented, then whatever offering that may be easy” (Surat Al- Baqarah, 196). Haj is one of the five pillars of Islam. It is a mandatory religious duty for Muslims, which must be carried out at least once in a lifetime by every adult Muslim who is physically and financially capable of undertaking the journey. Haj is not just a form of worship, but also a way of understanding the meaning of life. It teaches Muslims equality by bringing together people from different cultures and races to Makkah to worship God. It is well known that Haj is a spiritual and moral journey that helps Muslims to thank Allah for all the blessings. At the same time, protecting and conserving the environment and its natural resources is also a religious duty that all Muslims have to fulfill. However, very often during the Haj season, Muslims do not pay attention to the importance of protecting the environment and natural resources. This paper is structured in four sections: the first section addresses the environmental issues and concerns associated with the Haj; the second section looks at the Saudi efforts to overcome various environmental challenges associated with the Haj; the third section provides some insights into possible options and steps to deal with and alleviate some of the environmental stress associated with the Haj. The concluding section provides a short summary of the points raised earlier.
