What do you think about discoveries? In my opinion a lot of discoveries are no very helpful?

Your questions and statments are a bit confusing. They are't complete thoughts for one, and for two it just doesn't make sense. "If you think at our earth", did you mean 'that' instead of 'at', or did you mean 'about'?

Pollution wasn't a discovery, it was a byproduct of technological advance. "It'd be better get less technology", 'It'd be better get' did you mean 'Would it be better if there were less technology"? I can't understand it any other way.In your opinion what discoveries aren't very helpful?

Give us examples. In my opinion, one example is synthetic sweetners. Sure it doesn't have many calories, but its bad for you.

In my opinion, a lot of discoveries are helpful. Communication technology for instance is very helpful.It has allowed friends and relatives from across the globe to communicate with ease and without delay. Whereas before it could take weeks to get a letter from the US to ... any other continent.

The light bulb (electricity), has increased our productive day by many hours. During the winter time, if we were just to work for a couple hours and come home and do nothing, I would go crazy as I love to knit, and read after a day's work. I can't do that stuff in the dark.

Really though, you can argue either way that any specific piece of technology is beneficial or harmful.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
