Good news, unfortunately, rarely radiates with the power or urgency of bad news.

The mass-starvation concerns of the '70s-'80s were resolved by an army of agriculture and biological scientists developing revolutionary breakthroughs in staple food crops and farming techniques. These fundamentally staved off the "cold equations" starvation risk (most starvation in the modern era is logistical error; the food exists, it isn't where people are).

Unfortunately, key pieces of the solutions involved practices we know aren't sustainable indefinitely (fertilizer production is fossil-fuel heavy), so there's more work to be done (and some non-zero benefit if we were to discover that the global human population was falling without some mass-tragedy causing it).
