Food Security & Climate Change

Climate change and ocean acidification are two of the most pressing environmental issues of our time. They're caused by human activities like burning fossil fuels, and they're having a huge impact on our planet and its inhabitants. While we often hear about the ecological impacts of these problems, we don't talk enough about how they're affecting people's lives. I want to talk about one aspect of this that's often overlooked: food security.

Food security means having enough safe and nutritious food to eat. Climate change and ocean acidification are making it harder for people around the world to achieve this. In places where people depend on farming and fishing for their livelihoods, these problems are hitting especially hard.

One way climate change affects food security is by changing rainfall patterns. When temperatures rise, more water evaporates, leading to more droughts. This can be disastrous for farmers in areas without irrigation systems. Extreme weather events like floods and storms can also destroy crops and infrastructure, making it even harder for people to get enough to eat.

Ocean acidification is also affecting food security, especially for people who rely on fishing. As the pH of the ocean decreases, it becomes harder for certain species of marine life to build and maintain their shells and skeletons. This includes many kinds of seafood that we eat, like oysters, clams, and coral. Changes in temperature and nutrients can also change where fish live and how many there are, hurting fishermen and the people who depend on them.

It's important to remember that food security is a problem in rich countries too, not just poor ones. Even in the United States, droughts and other weather events can make it hard for people to get enough to eat, especially in rural areas where there isn't as much access to food.

So what can we do about this? One big thing is to cut down on our greenhouse gas emissions and stop climate change and ocean acidification from getting worse. This will take work from everyone: individuals, businesses, and governments. We also need to invest in better farming and fishing practices that can withstand the changes we're seeing. This could mean things like developing crops that can survive droughts or making aquaculture more sustainable so we don't rely as much on wild fish populations.
