10 things you didn’t know about the ozone layer

This coming September 16 is the international day for the preservation of the ozone layer.

In today’s post we tell you what it is exactly and 10 things you probably did not know about this essential element for life.

What is the ozone layer?

The ozone layer or ozonosphere is the area of ​​the Earth’s stratosphere that contains a relatively high concentration of ozone.

This layer, which extends from approximately 15 km to 50 km of altitude, gathers 90% of the ozone present in the atmosphere and absorbs 97 to 99% of low-frequency ultraviolet radiation.

This absorption is essential for life on our planet, hence the great concern that it disappear and therefore the immense importance that we preserve it.

10 things you didn’t know about the ozone layer

  1. The ozone layer was first observed in 1912 when Antarctic explorers said they had seen veil-like clouds in the polar stratosphere.
  2. Ozone began to be controlled in 1956 when the Halley Bay Observatory was established in Antarctica.

  1. The ozone layer is also studied from different satellites and aircraft.
  2. Ozone acts as a filter, or protective shield, against harmful, high-energy radiation that reaches the Earth, allowing others to pass through, such as long-wave ultraviolet, which in this way reaches the surface.
  3. The apparatus for measuring ozone in the stratosphere is called a spectrophotometer and was created by the British meteorologist G.M.B Dobson.
  4. Ozone concentration is measured in Dobson units in honor of this meteorologist.
  5. Its chemical formula is O3.
  6. Ozone closest to Earth removes pollutants from the atmosphere.
  7. Chlorofluorocarbons (CFCs) are the biggest culprit in the hole created and can be found in aerosols, air conditioners, refrigerators … among others.
  8. The ozone layer is located in a strip located between about 20 and about 30 kilometers above us.

The future of the ozone layer

It is believed that the ozone layer could be fully recovered by 2060, if protective measures continue to be applied.

These measures are included in the Montreal Protocol.

The use of industrial refrigerants and some aerosols have been destroying it for years.

Luckily measures are already being taken in this regard and various studies have shown that he is recovering little by little.

 

 

 

Kids and recycling Tips for children to learn to recycle

As we have already commented in previous posts, recycling must be incorporated into our day to day as one more routine. Many of us already have it fully assimilated

We know that children are sponges that get used to what we teach them very quickly, so it is very important to teach them to recycle at home from an early age.

In today’s post we give you a few tips so that you can learn to recycle and incorporate that learning into your day to day life.

The importance of teaching children to recycle

As parents, one of the things we want is that our children grow up healthy and happy in a preferably better world than we have now, (pandemic through).

A fundamental part of this purpose is to take care of the environment and be respectful of nature and this teaching is what we must transmit to our children.

It can be explained to a child that paper is obtained from trees and so that they do not disappear, we must try to spend as little paper as possible and that for this we can reuse dirty leaves to draw pictures, for example.

If we also explain that this is important because trees generate oxygen and are essential for the life of many animals, they will understand the true importance of recycling.

Children thus understand that their actions have consequences and that by spending less paper or throwing a plastic bottle where it belongs, they are helping to take care of the planet.

Explain the concept of the three r’s

To better understand the concept of recycling, we can explain the rule of the three R’s, which consists of:

– Reduce spending This can come in handy given the tendency of children to ask for everything. Podemos explicarles que no hay que comprar por comprar porque es perjudicial para la naturaleza

– Re-use We must make the most of everything we can. There are objects that we can surely fix and continue to use or use for another purpose.

There are many ideal crafts to do with children with empty cans or glass jars that we can decorate to use as jars to store markers, for example.

We will have a fun time with them and they will see that we can reuse many objects from our day to day.

-Recycle Putting different containers at home for each of the waste will stimulate the little ones in the house to collaborate in recycling.

We must teach them what type of waste each color corresponds to and place them in an accessible place for them. This way they will get into the habit of throwing the garbage where it belongs.

When it comes to taking it to the container, they can accompany us and help us deposit it where it belongs.

If they feel part of the whole process, it will not cost them to do it regularly at home, learning to recycle as a routine in their day to day.

Values ​​that recycling teaches them

In addition to the very value of recycling and caring for the environment, recycling teaches children to be responsible, since they have to take care of throwing waste where it belongs.

It also teaches them the importance of order, that everything must be put in its proper place, it instills in them that it is necessary to be careful and protect nature as much as possible.

It also helps them promote creativity, when it comes to reusing objects, many crafts can be made with which they will have fun and use their imagination to reconvert certain objects into others.

Let’s teach our children the importance of recycling and we will be giving them a great gift.
