OS SIDERÓFOROS
Como se sabe,o ferro tem um papel fundamental em plantas e microorganismos com capacidade fotossintética,ainda que não faça parte da estrutura da clorofila. Ora o ferro está muito pouco disponível em meios alcalinos,como nalguns solos e na água dos oceanos. Acontece que há organismos,como fungos,que segregam substâncias,os sideróforos,que conseguem solubilizar o ferro,permitindo,assim,que a fotossíntese ocorra.
DE UMA CAJADADA
Os materiais carvão mineral,petróleo e gás natural, deixados estar lá na sua condição de fóssil, são garantia,como bem se sabe,por um lado,de muito do oxigénio que por aí anda nos ares,e,por outro, do muito dióxido de carbono que nesses mesmos ares andaria,mas que disso ficou impedido. Trazendo esses fósseis materiais à luz do dia e deles fazendo uso para os combustar,pode dizer-se que,de uma cajadada,mata-se um "coelho",ou seja,o oxigénio,e se liberta outro "coelho",o dióxido de carbono.

GIGANTES DISFARÇADOS
Como se sabe,sabe-se muita coisa. Sabe-se,por exemplo,que é no ar que reside o grande reservatório de azoto,mais concretamente,azoto molecular,que não é directamente utilizável. Sabe-se,porém,que nos solos há bactérias,umas de vida livre, outras em simbiose com leguminosas e não-leguminosas,que o convertem em azoto amoniacal,e que nos oceanos há também microorganismos que fazem o mesmo. Ora,sabe-se muito bem que sem azoto utilizável não havia vida. Quer dizer que a vida está pendente de uns gigantes disfarçados de serezinhos muito pequeninos.

Assim,lá grito,e berro,e barafusto,rouco,
e sem salvar nenhum dos outros
nem me salvar a mim...

A minha grande alegria,
E a cada boca num beijo
Dar o pão de cada dia.
