Carbon dioxide fertilization theory

The carbon dioxide fertilization theory suggests that higher levels of CO₂ in the atmosphere can enhance plant growth because CO₂ is a key ingredient in photosynthesis, the process plants use to make their food. With more CO₂, many plants can grow faster and potentially produce more biomass and crops. However, this effect varies depending on other factors like nutrients, water, and temperature. While increased CO₂ might boost plant growth in some cases, it also contributes to climate change, which can harm ecosystems and agriculture in complex ways.
