I don’t think that the sentence as a whole is very cohesive.

It would read better like this –

“A research project concerning plants says that many different species of flowers express their sadness”

Although having said that my sentence isn’t really very fluent either. Is it only flowers that express sadness and is it only sadness that they express?

That flora have not got a fearful equipment and can’t journey soreness or concern or suffering as animals can. That, as a vegan, i’m somewhat in charge for the demise of fewer flora because of the fact i’m no longer helping the feeding of huge quantities of grain to farm animals in substitute for some meager pounds of crimson meat. Or, i do no longer say something in any respect. definitely, it somewhat is an extremely vulnerable argument on the section of whoever is making an attempt to communicate you. try announcing firstly which you’re feeling it somewhat is incorrect to kill animals no longer because of the fact they’re *residing* beings, yet because of the fact they’re *sentient* beings. maybe you will no longer get the “flora stay, too” argument in any respect.
