because we, humans, will not be able to live if the earth changes above 80C temperature, we cannot live under water, we will not be able to live without food sources in the form of plants or animals when they also die due to ecosystem damage here and there. We are the ones who have an interest in survival, not the earth. human presence means nothing to this planet. long before humans existed, the earth was fine.
And the world needs healing and there is a lot we need to do to save the planet.
The planet Earth needs to be clean and if we don't try our best to ensure that we put certain things in other then we might end up making the worse decision.
We need to join hands together and make sure that we don't make a big mistakes that would make our generation to regret our actions.
We can't save the planet. Why not? Because we can't even save ourselves.
The planet has millions of cubic miles. But we are so tiny that you could easily fit all the volume of all people into 2 cubic miles. We are nothing.
However, we exist. That means that the One Who made the planet, also made us. We need to look to Him to find salvation for ourselves. He will take care of the planet.
Some natural catastrophe has damaged the Earth badly like Covid, floods, Earth quacks, typhoon and any other but we humans are also damaging our Earth by deforestation, by polluting our environment , by killing and hunting, by overpopulation. These things have caused damage to Ozone layer , causes soil erosion.
So yes we save our planet and play our part .
