"The world population is growing by 75 million people each year. That's almost the size of Germany. Today, we're nearing 7 billion people. At this rate, we'll reach 9 billion people by 2040. And we all need to eat. But how? That's a critical issue the IonE tackles in our first Big Question video.
At the same time, agriculture is a major contributor to climate change and will suffer as an industry from the consequences."
