I would not like to live in a world with no love, because there will be no happiness, no kind words, everyone will fight with each other and hate each other. There will be no fun or laughter. There will be lots of hungry people, with no-one to care for them. All the animals will die, because there will be no one to care for them, and they will get hunted for our greed. Trees and plants will be cut down to make more space for factories, houses and shops. There will be lots of accidents on the roads because people will not obey the traffic laws. People will use bad language, they will steal and be bullies.
"Love is patient. Love is kind. It does not want what belongs to others. It does not brag. It is not proud. It is not rude. It does not look out for its own interest. It does not easily become angry. It does not keep track of other peoples wrong. Love is not happy with evil. But it is full of joy when the truth is spoken. It always protects. It always trusts. It always hopes. It never gives up." 1 Corinthians 13 vs 4-6
