What are greenhouse gases and the greenhouse effect?

When sunlight hits the earth, 100% comes in and 50% is absorbed by the land
The atmosphere acts like a glass-covered greenhouse that retains a certain amount of heat.
Provide the living environment and all conditions for human beings and creatures
But not all gases in the atmosphere perform this function.
.
If the atmosphere is thicker, the bounced heat cannot be reflected back into space
The temperature of the earth will be higher and higher.
.
Why is the atmosphere getting denser?
Human activities are the main reason~ (these seven gases)
CO2, CH4, N2O, NF3, SF6, HFCS, PFCS
Let the shield of our earth get thicker and thicker.
And then there's the extreme climate we're experiencing right now
extremely cold, extremely hot
so
Reducing greenhouse gas emissions is an unshirkable responsibility of enterprises.
Only in this way can the purpose of sustainable use be achieved.
