One reason why some people claim that climate has the greatest effect on people's lives is that climate affects daily activities such as clothing, food, and shelter. For instance, in cold climates, people might wear heavier clothes and cannot grow most crops compared to warm areas. This has a direct impact on agriculture, food availability, and even the cost of living. In addition, climate and weather conditions can influence people's moods. For instance, in colder regions, many people are unable to enjoy outdoor activities such as going to the beach, which can lead to feelings of boredom or sadness. In some extreme cases, long winters or frequent storms may cause mental health issues such as seasonal depression.
