The Montreal Protocol contains provisions to reduce the global amount of ozone-depleting substances. What is the role of engineers in the implementation of the Montreal Protocol?

Chemists discovered the issue of ozone depletion, and it seems that engineers are forced to abide by these regulatory provisions.

I still think that engineers contribute to enhancing human activities, in this case, the well-being of the protective ozone layer.

Thank you.

it is true that the youth today is more inclined towards engineering where one earns money in a shorter span of time. but has the earlier satisfaction of having cured a patient and having given new life to him, ceased to exist today or has this world become extremely materialistic?

i am a little confused, u should solve it using linear equations in two variables. and i wrote
let the no. of boys be y and the no of men be x then
1/4x+1/4y=3
1/2x+1/5y=4
but then the answer is a fraction and humans cant be fractions!!!

I think we're the scariest animals alive. We have done so much damage to our Earth and yet seemingly we're not doing anything about it.

Now those major countries(you know who they are) think nothing about saving our environment,they only think of the potential losses in profit they'll make once they cut down on gas emissions. But how worthless money and power is compared to our Earth and lives...there's only one Earth and one of each of us humans.

I was wondering what effect does Wi-fi have on earth itself, with all those energy/microwave in the air. sure there are researches trying to find out how it effect human, but what about this planet we are living in? will wi-fi be the next fossil fuel engine, convenient to human, but ultimately destructive to earth?
