Doom will come eventually. Even if we were to help it. The harm we caused is already too much for the Earth to accept. Accept that the Earth is SICK due to us, HUMANS. All we can do now is to slow the process of global warming and climate change. Maybe in the end is still for us, 3 more degrees in the temperature and Singapore will be covered under water. That is why we are trying to recycle things.
Before we even try to save Earth, we should save the other living thing which is facing facing extinction. Earth cannot live without it 'companions'. Without them, Earth is just like Mars. I am not trying to say bad things but, we cannot have so many children at home. With the increasing population, we will consume more food. Think about it, 2 parents were to give birth to 3 child, the parents dies and there will be one more extra person.
But Reducing, Recycling, Reusing is still a necessity to SLOW the global warming
