The world has three fundamental issues: population, politics, and economics. The population issue is the primary concern. Earth will soon reach 8.3 billion people. This year, 30.23 million people have been born, while 14.24 million have died, and the population continues to increase. This year's causes of death: infectious diseases rank first with 3 million deaths. Second is cancer with 1.87 million deaths. Third is child mortality under five years old with 1.73 million deaths. Smoking-related deaths number 1.14 million.
From the perspective of historical cycles, the most severe population decline has often not been caused by war, but by disease. However, as medical standards improve, diseases become less difficult to resolve. Today, infectious diseases are one of the main causes of death, particularly in poor countries (vaccine and medical facility shortages), but in wealthy countries chronic diseases such as heart disease and cancer are the primary causes (vaccine overuse, food safety issues).
