Today, April 22nd, is Earth Day. Exactly one year ago, the landmark Paris Agreement was signed, potentially marking a historic turning point against anthropogenic climate change. This is not a matter of preventative measures we must take to avoid a future problem: climate change is already happening, and the effects have been devastating, particularly in areas prone to drought. Ironically, it is the poorest countries which pollute the least which often bear the brunt of the impact. Yet all hope is not lost. Farmers in Africa are fighting back, and their resilience is critical for our food security.
