Biodiversity decline puts food supply at risk
Biodiversity decline around the globe is hurting our capacity to develop food. A new study from the United Nations found that biodiversity is a key element in producing sustainable and secure food sources — such as crops and livestock — is currently in a decline due to several factors, including climate change.
Scientists working with the Food and Agriculture Organization arm of the UN discovered that biodiversity has dropped across three levels: ecosystems, genetics and species. Without diversity in all three of the sectors, farmers and livestock owners will have a more difficult time raising reliable food sources in years to come.
“The proportion of livestock breeds at risk of extinction is increasing. Overall, the diversity of crops present in farmers’ fields has declined and threats to crop diversity are increasing,” the research stated.
The decline in species, for example, affects essential tasks in nature like managing pests and pollination. With an estimated 40 percent of species expected to go extinct over the next 20 to 30 years, this could have a devastating impact all around the world.
Large mammals are also hurting from a lack of biodiversity, with over 25 percent of livestock on the verge of extinction. Further, there are only around seven percent of livestock breeds that are not at risk of extinction, which is alarming for the future of breeding.
The UN report concluded that climate change is a contributing factor in the decline of biodiversity. Other human interactions with the environment are also leading to a change in biodiversity, including pollution, demographic changes, land abuse, and overcultivation. The study also warned that our ability to monitor changes in biodiversity is limited, which means we might be worse off than we think.
Fortunately, the topic of biodiversity is getting more attention by worldwide leaders. In fact, it will take center stage at the upcoming G7 meeting and the World Conservation Congress gathering. It is unclear what will be done to combat the issue, but biodiversity decline is a problem that can no longer go ignored.
