A number of scientists and researchers in a study published on January 15 in a reputable medical journal have called for major and widespread changes in people's eating habits to improve health and prevent the Earth from 'heading towards destruction.' These researchers state that changes in the diet of Earth's inhabitants are essential to prevent a 'catastrophic' climate impact on our planet. Nearly 40 researchers involved in the recent study are experts in health and nutrition, climate, and the environment. The researchers advocate for a shift towards a plant-based diet, grounded in the culture, agriculture, and customs of people around the world. They suggest that Earth's inhabitants should reduce their meat and sugar consumption to at least half of what they currently consume, significantly decrease dairy intake, consume more legumes, and double their intake of nuts, fruits, and vegetables. Tim Lang, a professor at the University of London and the lead author of the study, stated, 'We are in a catastrophic situation.' Research managed by Professor Lang indicates that about one billion people on Earth are hungry, while two billion eat excessively and incorrectly; this ultimately leads to obesity, heart disease, and diabetes becoming widespread issues. The new research is the result of three years of studies involving 37 researchers from 16 countries. However, dairy and meat production companies have strongly criticized this research, claiming that the researchers have ignored the positive health impacts of consuming dairy and meat. The research was organized by the non-governmental organization 'EAT' in Sweden, and published by The Lancet, one of the most reputable and well-known medical journals in the UK.
