Nutrition is an essential part of life. And when it comes to eating, we usually just think about going to the supermarket or going to KFC and the food is there, ready to eat. But it would be difficult for us to realize that the state of food security is threatened and that soon we will not have enough food to feed around 8 billion people and that we will soon have to find alternatives to what we eat today.

Changes in weather conditions that become more erratic and intense, average temperatures that increase or decrease, rising sea levels and drastic changes in landscapes and biomes clearly show that the balance of nature is being disrupted . This is a major problem because plants and trees cannot quickly adapt to new environmental changes. This strongly affects agriculture because, obviously, agriculture depends on nature. And because plants don't adapt quickly to changes, they will die, leading to a very large food crisis. Another major concern for food security is increasing soil erosion. According to the World Wide Fund for Nature (WWF), we have lost almost all of Earth's topsoil over the past 150 years. Topsoil is where plants get their nutrients. This is due to deforestation, overgrazing and the continued use of pesticides. Soil is washed into rivers and oceans which then pollute aquatic life or eventually clog our water pipes and contribute to flooding. Because we will be left with barren land, we will depend on the use of chemical solutions to enrich the land with necessary nutrients. “Because we are left with barren land, we depend on chemical fertilizers to enrich the land. But often these fertilizers destroy the balance of nature, polluting the soil, killing soil biodiversity and eventually contaminating our food. Another issue regarding food security is changing diets and incomes. The number of people working in agriculture is decreasing because few people want to become farmers and prefer to work in urban areas, such as in offices. Jobs in urban areas are more rewarding and offer better income than those working in agriculture and people would then want to switch to a "westernized" diet, i.e. eating more meat. The growing demand for meat means that people will need more pastures and to do this they will have to cut down forests and the process will continue, leading to more greenhouse gas emissions and pollution. And we know that methane produced by cows is 25 to 100 times more destructive than CO2 emissions from factories and vehicles alone. Faced with these and other problems regarding our food security, we will soon have to find alternative solutions to cope with the new circumstances and the loss of food security. The first alternative food source should be to use fossil fuels to grow many things, mushrooms are a good example. Mushrooms can grow on many substances, but we can use things like coal to grow mushrooms and we can..
