Five Ways Climate Change is Intensifying the Threats to Plant Health
- May 12, 2022
- UN. Food and Agriculture Organization.
- The spread of plant diseases and pests is on the rise due to a changing climate. Plants are humans’ best friends and main allies in life on earth. Plants are responsible for 98 percent of the oxygen we breathe and make up 80 percent of our daily calorie intake. However, we often take them for granted, not realizing the importance of keeping them healthy. Every year up to 40 percent of food crops is lost to plant pests and diseases. These losses in both yields and income have a devastating effect on the poorest communities who base their livelihoods on agriculture.
