International ozone layer protection day, protect the blue sky, protect this blue planet

International Ozone layer Protection Day

Humans have a common parasol

An umbrella of life -ozone layer

It carrys human hits

In the long evolution of the earth

From the deep sea to the shallow sea and the surface of the earth

Then evolve more complicated species

Ozone layer guards the future of human beings

And how much do humans know about the ozone layer?

What is ozone layer?

Ozone is a kind of alien body of oxygen. It has a fishy smell of light blue gases. More than 90%of the ozone in the atmosphere exists in the relatively rich atmospheric flow layer of ozone molecules 25-30 kilometers from the earth to form the ozone layer.

It can absorb more than 99%of the harmful solar ultraviolet rays to humans, protecting life on the earth from short -wave ultraviolet damage, and is a protective umbrella for biological survival and reproduction on the planet.

Why protect the ozone layer?

In 1974, Roland and Molitt of the University of California found that the ozone consumption gas used in qi fog and coolant caused severe damage to the atmospheric ozone layer. Earth greenhouse effects have seriously affected global climate, ecological balance, and agricultural production. Since then, countries around the world are competing to invest in manpower, material and financial resources to carry out the research, development, and promotion of Freon alternatives.

What should I do to protect the ozone layer?

1. Buy products with the "Ozone Care Layer" or "Carbon -free Carbon" logo, such as gas mist tanks, refrigerators, fire extinguishers, etc., use energy -saving and environmentally friendly home appliances.

2. Reasonably handle waste refrigerators and electrical appliances. Before abandoned electrical appliances, the carbon fluoride and chloride hydrocarbons refrigerant should be removed (asking the public service department or home appliance company of the town or home appliance company, the situation where the electrical refrigerant is reused).

3. Appraisal existing equipment (such as water -cooled machines, air conditioners, cleaning agents, fire extinguishers) and supplies (such as gas mist, sponge pads/mattress, modified solution) use substances that consume ozone layers, and use economically valid replacement objects to replace objects. Let's replace them.

4. Tell the importance of protecting the ozone layer around them and let them know the destructive effects of those ozone layers on the atmosphere and human health.
