I was aware of several of the points you raise, especially that more than the Amazon, the oceans are the lungs of the earth, I love documentaries and my brother is totally fanatical about them, we often talk about it.
People have been using everything inappropriately for decades...., and governments... well... governments love money, it's all about power and money, they don't give a damn about anything else.
Now they say farming is bad... crazy things while they are going around the world with aeroplanes dropping chemtrails, I don't know if you saw them. A striped sky everywhere... not only affects the health of people with allergies for example, but they leave fields unusable, generate droughts etc etc etc etc. Many consequences.... the reason? Power, control and money.
In the seas the same thing, indiscriminate fishing... killing species. They do it again and again...
The human species... it's a disaster. I don't know what will be left in a few years...
There's many problems and few solutions, or people willing to actively pursue the solutions that are there. It's on all of us really, but the individual doesn't have the ability to stop commercial fishing, (for instance), so the little people are a bit helpless. However, people could stop eating seafood...that'll render the commercial fishing industry redundant...it'll not happen though.
Humanity is on a fast-track to its own demise. No one wants to make enough changes...when it all comes crashing down I wonder if there'll be anyone left to say, I told you so. Probably not.
You are absolutely right... perhaps there is no one to say that, or few thinking minds. Sad future, isn't it? Maybe we don't see it, but... what about those to come?
