Oxygen in the air is likely dropping too

Why?

Because of de-forestation worldwide. For example, most of the U.S. was covered with forests that have now been cut down. The same it true in the rain forests of Brazil and elsewhere all over the world. So, because humans are at 8 billion strong and breathing oxygen and turning it into Carbon dioxide 24 hours a day and because Cattle, goats, sheep and pigs are breathing and turning everything into carbon dioxide more than ever before, and because of world wide deforestation this has also reduced Oxygen levels too. ON top of all that all cars, trucks, ships and planes worldwide that burn anything reduce oxygen levels too. Burning forests and burning wood also continually reduces Oxygen levels too. So, it is not only the oceans losing oxygen, the air is losing oxygen too. There was more oxygen in the air to breathe when I was growing up than now by far. There were also 6 billion less people on earth when I grew up too.

So, if your kids get asthma and other breathing problems don't be surprised because there isn't enough oxygen in the air that much to sustain humans. So, only humans with exceptional conversion levels for oxygen are eventually going to be alive.It's one of the reasons I live not only in a forest (that creates oxygen from Carbon Dioxide but also next to an ocean which also creates oxygen more than other places too. So, having enough oxygen to breathe also allows you to live longer with less stress upon your body. And if you add to this a good organic diet it will also increase the length of your lives.
