A couple of articles in the NYT on the effects of climate change. First, one on the oceans: "If fossil-fuel emissions continue to rise rapidly, for instance, the maximum amount of fish in the ocean that can be sustainably caught could decrease by as much as a quarter by century’s end. That would have sweeping implications for global food security: Fish and seafood provide about 17 percent of the world’s animal protein, and millions of people worldwide depend on fishing economies for their livelihoods."
Second, one on agriculture and food production more generally: "Meat and dairy, particularly from cows, have an outsize impact, with livestock accounting for around 14.5 percent of the world’s greenhouse gases each year....Consuming less red meat and dairy will typically have the biggest impact for most people in wealthy countries. That doesn’t necessarily mean going vegan. You might just eat less of the foods with the biggest climate footprints, like beef, lamb and cheese....plant-based foods like beans, pulses, grains and soy tend to be the most climate-friendly options of all."
