If our society chooses to ignore the reality of limited water resources, the number of people impacted will double from 2.4 billion people to 4.8 billion - 52% of the world's population! The increase in population will drive a greater demand for food and economic development (i.e., water). Approximately half (49%) of global grain production and 45% of total GDP ($63 trillion) will be at risk due to water stress by 2050. Consider that the total GDP at risk is 1.5 times the entire global economy today!
Pyruvate kinase blood test. The pyruvate kinase test measures the level of the enzyme pyruvate kinase in the blood. Pyruvate kinase is an enzyme found in red blood cells. It helps change sugar in the blood (glucose) to energy when oxygen levels are low. A blood sample is needed. In the laboratory, white blood cells are removed from the blood sample because they can alter test results.
