If you had the resources to accomplish something great in the world, what would you do?

Legendary investor Warren Buffett posed this challenge to his son in 2006, when he announced he was leaving the bulk of his fortune to philanthropy. So, Howard G. Buffett set out to help the most vulnerable people on Earth–nearly a billion individuals who lack basic food security. And Howard has given himself a deadline: forty years to put more than $3 billion to work on this challenge.

Each of us has about forty chances to accomplish our goals in life. Howard learned this lesson through his passion for farming: all farmers can expect to have about forty growing seasons, giving them just forty chances to improve on every harvest. This lesson applies to all of us, however, because we all have about forty productive years to do the best job we can, whatever our passions may be.

Forty Chances: Finding Hope in a Hungry World is a book that captures Howard’s journey. We join him around the world as he seeks out new approaches to ease the suffering of so many. It is told in a unique format: forty stories that will provide readers a compelling look at Howard’s lessons learned, ranging from his own backyard to some of the most difficult and dangerous places on Earth.

From one of America’s most prominent philanthropists, an eye-opening, myth-busting new perspective on the crisis at the U.S.-Mexico border.

Howard G. Buffett has seen first-hand the devastating impact of cheap Mexican heroin and other opiate cocktails across America. Fueled by failing border policies and lawlessness in Mexico and Central America, drugs are pouring over the nation’s southern border in record quantities, turning Americans into addicts and migrants into drug mules — and killing us in record numbers.

Politicians talk about a border crisis and an opioid crisis as separate issues. To Buffett, a landowner on the U.S. border with Mexico and now a sheriff in Illinois, these are intimately connected. Ineffective border policies not only put residents in border states like Texas and Arizona in harm’s way, they put American lives in states like Oregon, Pennsylvania, and Vermont at risk.

Mexican cartels have grown astonishingly powerful by exploiting both the gaps in our border security strategy and the desperation of migrants — all while profiting enormously off America’s growing addiction to drugs. The solution isn’t a wall. In this groundbreaking book, Buffett outlines a realistic, effective, and bi-partisan approach to fighting cartels, strengthening our national security, and tackling the roots of the chaos below the border.
