Food Production: Food Security 🥘 GCSE Biology Learning & Revision

In this episode, we discuss food security. Global food security faces significant challenges in ensuring sufficient, safe, and nutritious food for everyone. High birth rates, particularly in sub-Saharan Africa, exacerbate the issue. The emergence of new agricultural pests and diseases, coupled with the increasing frequency of extreme weather events linked to climate change, threaten crop yields. Conflicts disrupt access to essential food and water resources. Rising costs of agricultural inputs, like fertiliser, further reduce production. Finally, dietary changes in wealthier nations result in substantial "food miles" as food is transported globally, adding to environmental concerns.
