man--------- Sand has a very low bearing capacity. Hence, your feet tend to sink into it. While walking, you have to continually 'dig' yourself out of the sand with every step you tend to sink into it. While walking, you have

We know that Pressure = Force/Area

 

The feet of humans covers very little surface area. The entire weight of the body is concentrated on very little are, thereby, increasing the pressure.

Camels are heavier than humans, but they have large feet which cover more surface area. The weight is hence distributed evenly and pressure is lesser.

 

Hence, humans sink into sand while camels don't.
