nobody explains why birds survive :o
Because you failed to ask the right person.
If you are interested in that topic - just ask ME.
I will explain this to you.
During the times of the great dinosaurs, the CO2 content of the air was about 5%. This was ensured by volcanoes and soil bacteria.
As a result of variations in the solar cycle, the climate began to cool, which had a profound impact on both bacteria and volcanoes. Consequently, the concentration of CO2 in the atmosphere decreased significantly. In fact, the current CO2 level is just 0.04%.
What you no longer learn in school today is that CO2 in the air is the primary source of carbon for plants. Large herbivores required large plants!
A leaf back in the day could easily be 2 meters in size. Of course not all, but many. Only a few trees from that age have survived in USA.
Chemically speaking, these leaves are composed of "carbohydrates", which are essentially water and CO2.
However, when the primary source of carbon dwindles, nature can no longer adequately support large plants. As a result, these large plants die off, and subsequently, the large herbivores that depend on them for food also perish.
The carnivorous dinosaurs soon had only "small prey" left, and thus, their days were numbered as well.
For birds, this was not a problem, and it only tangentially relates to asteroid impacts.
It was a climate change event, the kind that nature always triggers when it switches evolutionary cycles.

Yeah..i get it ..i think
Ahh all this theories makes confusion..
like climate changes..which are not just connected with solar
cycles then with our sytem is currently in galaxy ..my theory ;D
