Nutrition is a vital part of life. And when it comes to eating, we usually just think about going to the supermarket or KFC and the food is there, ready to be eaten. But it would be difficult for us to realize that the state of food security is in danger and soon we would not have enough food to feed around 8 billion people, and we would soon have to find alternative solutions to what we eat today. to plagiarism.

Changes in weather patterns becoming more erratic and more intense, average temperatures rising or falling, rising sea levels, and huge drastic changes in landscapes and biomes show a clear indication that the balance of nature is messed up . This is a big problem because plants and trees cannot quickly adapt to new changes in the environment. This heavily affects agriculture because, of course, agriculture depends on nature. And because plants do not adapt quickly to changes, they will die, causing a very serious food crisis. Another major food security concern is increasing soil erosion. According to the World Wide Fund for Nature (or WWF), over the last 150 years we have lost almost all of the Earth's land surface. Soil is where plants get their nutrients. This is caused by deforestation, overgrazing and the continuous use of pesticides. Soil gets washed into rivers and oceans which then pollutes aquatic life or ends up clogging our water pipes and contributing to flooding. As we end up with infertile soils, we will depend on the use of chemical solutions to enrich the soil with the necessary nutrients. “Because we are left with barren land, we depend on chemical fertilizers to enrich it. Often, however, these fertilizers destroy the balance of nature, polluting the soil, killing soil biodiversity and ultimately contaminating our food.” Another issue related to food security is changing diets and incomes. The number of people working in the agricultural sector is decreasing because not many people want to become farmers and prefer to work in urban areas as office jobs. Jobs in urban areas are more rewarding and provide a better income than work in agriculture and people would therefore like to switch to a “Westernized” diet, meaning they want to eat more meat. The growing demand for meat means that people will need more grazing land and to do so they will have to cut down forests and the process will continue, leading to more greenhouse gas emissions and pollution. And it is known that the methane produced by cows is 25-100 times more destructive than the CO2 emissions produced by factories and vehicles alone combined. With these issues and more affecting our food security, we will soon have to find alternative solutions to deal with new circumstances and the loss of food security. The first alternative food source should be the use of fossil fuels as a means to grow many things, a great example being mushrooms. Mushrooms can grow on many substances, but we can use things like charcoal to grow them, and we can eat them. Not only are mushrooms healthy and full of many nutrients, but they have also been shown to have a low environmental impact: only 1.8 liters of water are needed to grow half a kilo of mushrooms and we can produce around a million kilos of mushrooms alone.
