According to the poet, the world will perish as a result of the fire that represents desire. But, if the world had to end twice, it would be because of a hate of "ice." He thinks that if everyone hated the ice instead, then this fatal element would not be needed to destroy everything. In conclusion, the world will end because of hatred. This idea comes from a poem by Catullus called "Haeduqum etiam dii maligni," or "The Hated God also sends evil days." It should be noted that this poem was written about 56 BC at a time when many people believed that the world would end in a great flood. Modern scientists agree that the Earth will be destroyed by fire, but they believe that this will happen in five billion years at the most. They say that the Earth has been through such changes before and will be able to handle another one. Some scientists believe that there will be a global collision course with Venus or Mars, and that this will cause all the water on both planets to evaporate within a few hundred years. Then, the remaining land will be subjected to terrible heat until it becomes useless for living organisms. Other scientists think that a huge solar flare will destroy us today. Or perhaps we will just all die out due to genetic drift.
