Объяснение:
Among all the planets in the solar system, Earth is the only planet that has life. And in order to save life on Earth, each of us must make a little effort. For example, if I still have trash, I'd rather put it in my pocket than throw it out on the street.
There are many natural hazards on the planet, whether it's a volcano or a tsunami, or an earthquake or a dust storm, each of them can cause damage to humanity.
If we all disappear from the Earth in one day, I think that the planet will self-clean and eventually come to a pervodannyy form.
I treat our planet quite respectfully and am generally grateful for the fact that it exists.
The climate may change for the following reasons:
1) change in size, terrain; 2) change in the luminosity of the Sun;
3) changes in the parameters of the earth's orbit and axis. All this can lead to climate change.
