5Lagos, Nigeria

Lagos, a bustling economic hub in West Africa, faces severe sanitation challenges. Streets are often cluttered with waste, and drainage systems struggle during heavy rainfall, causing flooding and spreading debris. 

Air pollution from traffic and industrial zones adds another layer of discomfort for visitors. While Lagos offers vibrant markets, music, and cultural experiences, tourists should approach the city with patience and practical precautions, such as bottled water and protective footwear.
