Because, if no Rubisco is avalible to fix CO2, the Calvin Cycle would not be in action, photosynthesis would be incomplete, the ususal products: Proteins, Lipids, Carbohydrates (O2) and vitamins/minerals would not be made. After all the food stores ran out, all Hetrotrophs and Autotrophs would have no food to survive.
So Basically, Rubisco is the bain of life.

Which is the most important and abundant carbon-fixing enzyme on earth
chloroplasts
The production of glucose takes place during the light independent reactions (Calvin cycle) in the stroma of the chloroplast.

RuBisCO is the most common protein on Earth. This protein is an enzyme.

Rubisco is the key enzyme for the dark reactions, also know as the Calvin Cycle. It is thought to be the most abundant protein on Earth.
Collagen is the most abundant protein in the body as it is the main protein of connective tissue, including skin, bones, cartilage, blood vessels, and more! Collagen makes up about 25% of the average human body's protein content. The second most abundant protein in humans is actin (20%).
Pepsin is the most important enzyme in gastric juice. It begins the digestion of nearly all types of dietary protein into polypeptides. (Originates from the inactive form pepsinogen)
Enzymes function optimally at a patricular temperature and pH. If the temperature is decreased or increased, the enzyme will not function as effectively. The enzyme is most active only at a patricular temperature and pH. Hence, these two factors are very important for enzyme action.
