The more I see the more I find that human beings are exactly like bacteria. Just like bacteria invade the body we have invaded Gaia or mother earth. Just as we try to fight off infection with antibodies earth has been trying to get rid of us with viruses and bacteria. In the olden times it was plague, small pox, cholera. Today it is HIV, XDR TB, malaria. Just as bacteria develop resistance to antibiotics we invent vaccines against our infections and just as bacteria exchange immunity genes among different species so we supply vaccines and antibiotics to each other. Just as bacteria breed regardless of the health of the host so do we. Since humans live only 70 odd years bacteria live around 20 minutes and multiply fast but mother earth is 4 billion years old so we can take longer. Just as bacteria cause fever in the human host so we are causing fever in our mother in the form of global warming. If we fail to get rid of infection we die and this is likely to happen to mother earth if she fails to get rid of us. Once the host is dead the infecting bacteria also die in the fire that consumes the body so we will all die if earth succumbs. The only way bacteria survive is by invading a fresh human before the first one is dead. Maybe we humans will also survive by infecting another planet before earth dies. Unless there is another life form ready to sterilise us.
