A casual essay, Thanks for comments and [corrections] for amending!

Staring at the people with innumerable pairs of fierce eyes as wild tigers over our heads, the ruthless heat and dazzling sunlight, which not only greedily suck the dew from the grass, but [even] dry the earthworms and bake the ants as their meal, have captured the entire summer.

Some small animals stay deep in their holes evading them [like me! eheh]. It seems that the [--> are you referring to the heat and sunlight? In this case I would use "those" instead of "the"] horrific wild animals have lost their temper and patience, they are attempting to burn everything on the earth and swallow up every inch of our sins.

However, we are smart human-beings, we are not scared of you, wherever you are! You know why? That's because we have the greatest invention: air-conditioners... ahah! We can get cool air from them.
Thanks to our respectful inventors! [--> this means "inventors who give respect"; is that what you mean? If you mean to say that the inventors deserve respect, I would say something like:
"Thanks to our honorable inventors!"]

Hey, stop challenging the heat and sunlight! They seem to be already angry, at least here in Italy, I fear that they may overreact! (just kidding).

That was nice! :)
