Gene Editing for Good
How CRISPR Could Transform Global Development
By Bill Gates, For Foreign Affairs Magazine
Today, more people are living healthy, productive lives than ever before. This good news may come as a surprise, but there is plenty of evidence for it. Since the early 1990s, global child mortality has been cut in half. There have been massive reductions in cases of tuberculosis, malaria, and HIV/AIDS. The incidence of polio has decreased by 99 percent, bringing the world to the verge of eradicating a major infectious disease, a feat humanity has accomplished only once before, with smallpox. The proportion of the world’s population in extreme poverty, defined by the World Bank as living on less than $1.90 per day, has fallen from 35 percent to about 11 percent.
Continued progress is not inevitable, however, and a great deal of unnecessary suffering and inequity remains. By the end of this year, five million children under the age of five will have died—mostly in poor countries and mostly from preventable causes. Hundreds of millions of other children will continue to suffer needlessly from diseases and malnutrition that can cause lifelong cognitive and physical disabilities. And more than 750 million people—mostly rural farm families in sub-Saharan Africa and South Asia—still live in extreme poverty, according to World Bank estimates. The women and girls among them, in particular, are denied economic opportunity.
Some of the remaining suffering can be eased by continuing to fund the development assistance programs and multilateral partnerships that are known to work. These efforts can help sustain progress, especially as the world gets better at using data to help guide the allocation of resources. But ultimately, eliminating the most persistent diseases and causes of poverty will require scientific discovery and technological innovations.
That includes CRISPR and other technologies for targeted gene editing. Over the next decade, gene editing could help humanity overcome some of the biggest and most persistent challenges in global health and development. The technology is making it much easier for scientists to discover better diagnostics, treatments, and other tools to fight diseases that still kill and disable millions of people every year, primarily the poor. It is also accelerating research that could help end extreme poverty by enabling millions of farmers in the developing world to grow crops and raise livestock that are more productive, more nutritious, and hardier. New technologies are often met with skepticism. But if the world is to continue the remarkable progress of the past few decades, it is vital that scientists, subject to safety and ethics guidelines, be encouraged to continue taking advantage of such promising tools as CRISPR.
