Human growth is one of the most pressing environmental issues along with famine, climate change, food crisis, poverty and the threat of terrorism and nuclear weapons. Population growth dependent on the current population — the more people there are at any given time, the more children will be born, and the population will grow faster and faster every year. However, food production is limited by available land, water for irrigation, and so on. Also, food production might increase by the same amount every year. A food security crisis is considered a famine when, according to the United Nations, “20 percent of households face extreme food shortages with a limited ability to cope; acute malnutrition rates exceed 30 percent; and the death rate exceeds two persons per day per 10,000 persons.”
One of the factors, which influence on the food crisis, is climate change. Climate change directly affects food production, which can create widespread food insecurity and famine. Furthermore, climate change will create conditions outside of human experience, challenging farmers’ ability to adapt. While farmers with more wealth and resources are more likely to be able to adapt to a changing climate through investments in new technologies, seed varieties and cropping patterns, poorer subsistence farmers will be less likely to adapt and are thus more vulnerable. Extreme variation in weather and intense effects of climate change such as rising temperatures, rainfall and droughts prevent farmers from making accurate predictions regarding agricultural seasons.
Because of these global issues, which will effect on every country, our generation should take a part in solving such a big and destroying problems as climate change and its consequences. We are creating the future of our Earth and the future of humans, thus we should act now. Think global, act local!
