What about the climate change?

I'd like to talk about the climate change. What kind of world are we going to leave to our sons[1]? Sincerely, I believe we could do more in order to try to/and fix it. All we of us know what are the effects of our behaviour are and we aren't doing anything to solve them. Even Also, we are listening to politicians claim talking about the climate change is a hoax and surely many people believe is believing that. As far as I'm corncerned, that there is an evidence and we only have to look at how many animal species are endangered and even facing the extinction. Without a doubt I really know what I'm going to do and I'm pretty confident of what kind of world I want to leave to those who won't wouldn't be guilty of our selfishness.

What about the climate change?

I would like to make a remark on the climate change. What kind of world will future generations inherit? Sincerely, I am convinced we need to do more to fix it. Everyone is aware of the environmental consequences of our ecological behavior and we aren't doing anything to reduce or eradicate them. Instead, we hear politicians endorsing the position that "climate change is some kind of a hoax" and surely a good deal of people believe that. To see the evidence of our negative impact, we should merely look at the number of animal species endangered and even facing extinction. Doubtless, I know what I'm going to do about that and I'm pretty confident of what kind of world I wish to leave our descendants who won't be guilty of our selfishness.

In fact, your piece of thought is correct,only some minor changes were added to it to sound more natural and vivid.
