Most developing countries are located in tropical regions. Life is hard to live when you live in these tropical regions. One of the reasons is agriculture, the soil is bad and the plants have fewer carbohydrates. Furthermore, people in poor countries are more easily exposed to diseases such as arboviruses, bacterial infections and parasitic diseases. All low-income countries are affected by at least five diseases simultaneously. Furthermore, low-income countries lack crops, which makes it difficult to produce food, and therefore there is nothing to sell; causing hunger and an increase in famines. Many people depend on good soil, since that is where most income comes from in poor countries. Most workers in low-income countries engage in unpaid self- or family-based work, such as in the agricultural sector, and particularly in subsistence farming (Food and Agriculture Organization of the United Nations, 2012: 18 ). Soil is destroyed due to many reasons such as deforestation, desertification, land degradation and so on. Therefore, if the soil is destroyed, many people lose their jobs. Between 1999 and 2009, agricultural employment accounted for half of total employment, and more than 1 billion people are employed in agriculture worldwide. In sub-Saharan Africa, agriculture accounts for more than 60% of the entire workforce (Food and Agriculture Organization of the United Nations, 2012: 18). Plus, when it comes to geography, travel also comes into play. Low-income countries tend to be isolated and poorly connected. Countries like Bolivia, Paraguay and Afghanistan are completely landlocked. Without communication with the outside world this will undoubtedly mean less money for those countries. This also means that they have higher transportation costs and not everyone can afford it. Furthermore, depending on where the country is located, they can easily be affected by natural disasters
