CHLOROPHYLL AND ENERGY 211 



On the other hand, no advertisement is needed for the 

 authentic chlorophyll, since no one has ever thought of doing 

 without it. 



The Benefits of Chlorophyll 



Among the very diverse material needs of humanity 

 there are three of primary importance: we must nourish the 

 body with food; we must protect it by wearing clothes and, 

 in an unfavourable cUmate, by creating a more comfortable 

 atmosphere indoors; finally, we must increase the power 

 available to us for work. We need nutrition, protection 

 and energy. 



For nutrition, we use vegetable or animal products which 

 are all derived from chlorophyll, since the animals feed either 

 on vegetation or on other animals which feed on it. Our food 

 therefore depends more or less directly on chlorophyll; it 

 enables carbon to enter into the hfe cycle and puts at our 

 disposal material charged by it with a chemical potential 

 which can be Hberated through the various paths of oxidation- 

 reduction. 



For our protection, we wear clothes made from material 

 produced directly by chlorophyll, like cotton, or indirectly 

 Uke wool, leather or fur. Our houses also depend on chloro- 

 phyll, to the extent to which wood is used in their construction. 



To provide energy, we use petrol or coal, and nearly all 

 the transport on the road and even on the railway is effected 

 by means of those valuable deposits left by chlorophyll, 

 which worked for us in the distant geological ages. The same 

 energy warms us still and enables us to prepare our meals. 

 Although it is now supplemented by hydro-electricity, we 

 are still far from being able to dispense with it. 



Thus on all sides we find this indispensable chlorophyll 

 on which life is so dependent that the problem of its origin is 

 practically identical with that of the origin of chlorophyll. 

 When chlorophyll appeared, life became self-sufficient and, 

 sure of its future, the immense animaf and vegetable pyramid 

 could rise, while chlorophyll indefatigably provided its means
