What effect does the use of words with strong positive connotations have on this excerpt

Which excerpt from “the girl who silenced the world for five minutes” supports suzuki’s argument that she is “losing [her] future”? coming here today, i have no hidden agenda. losing my future is not like losing an election or a few points on the stock market. and now we hear about animals and plants going extinct every day – vanishing forever. i'm only a child, yet i know we are all in this together and should act as one single world towards one single goal.

Can someone me with this english question

It is clearly expressed. what does that mean?
