How would you call someone who is attacking his food supply?

It is really a humiliating irony when we are unable to realize CO2 in air is our sole source for all our food we eat without one exception. Proteins, carbohydrates, saccharides, oils, fats, alcohols, starches, meats, vegetables, fruits, bakery, cheese all these are carbon compounds coming from CO2 in air.
Carbon is the most important element of the periodic table, carbon compounds outnumber all the compounds of all the other elements all grouped together by a minimum ratio of 20 to 1. Unhappily climate scientists are attacking CO2 in air???
While our sun nuclear reactor is slowing down causing the climate change we are facing. It happened many times before, and we faced many previous famines.
