There are five people on the picture.
They are men and immigrants. They are in the desert because we can see cactuses and trees. They are near to a border. The men are holding bagpacks and they are walking in group. Any men are talking, they are just walking. They are looking down at the road. They may be tired because they might be walked a very long time. They could be flee their contry because they are poor, they want a better future or looking for jobs in order to earn money. They may be consired as people who want a job anybody else want, for their advocated. They might be friends who want a job and have a better healthcare and a better education. They may be want for a peaceful life and they could be commited any crimes. Immigrants can die because they haven't got the adequate equipments for survive severe weather conditions.
