Plant Health Directly Depends on Human Action

Since before the systematic and scientific study of plants, humans had already developed a close relationship with these organisms. This has allowed us to survive and develop more complex and sophisticated life forms. Our dependence on plants goes even further, since they produce 98% of the oxygen we breathe and an estimated 80% of our diet is plant-based. With this data, it is necessary to understand and effectively address emerging threats that may jeopardize the health of plant species in different ecosystems.   

The concept of plant health is a broad term that can include multiple elements, such as pathogens present in plant species. However, there are other proposals that involve the consequences of human action through agricultural production, trade and other activities on the health of plant species in certain ecosystems. Experts point out that one of the most important threats is the introduction of non-endemic species, as they endanger the ecosystem balance in some regions of the Americas.   

In Argentina, for example, exotic conifers were introduced for productive purposes, due to their ability to adapt to water deficit frequencies. But, according to Pedro Laterra, member of the IAI’s Scientific Advisory Committee, poor management of these species threatens biodiversity and ecosystem services in places where they have not been invited, increasing the likelihood of fires.   

Native biodiversity is fundamental to the protection of countries' vital ecosystems, food security and biosecurity. Governments should consider the potential risks of plant imbalance, considering scientific and traditional knowledges when making economic decisions.
