Because the amount of atmospheric carbon is well known and conservation of matter requires a balanced global carbon budget, this previously unaccounted for source of carbon to the atmosphere implies the existence of an additional continental carbon sink such as higher rates of biomass accrual in forests.
(World Cancer Research Fund/American Institute for Cancer Research (2007) Food, Nutrition, Physical Activity and the Prevention of Cancer: a Global Perspective. AICR: Washington, DC). AICR/WCRF was the first organization to note that, after smoking, obesity is the most important preventable cause of cancer. While obesity is clearly linked to risk for developing many forms of cancer, the deleterious impact of obesity on prognosis has proven even more compelling in several studies.
Obesity, categorized as a body mass index (BMI) of 30 or more, is linked to more than 40 diseases including type 2 diabetes, heart disease, stroke, osteoarthritis and cancer2,3. Obesity is associated with a 50-100% increased risk of premature death compared to healthy weight individuals4.
