"Investigations are underway to determine the cause of the mass fish die-off. Huge numbers of dead fish were first spotted near the southwestern Polish town of Olawa in late July, along with dead animals such as beavers.

Przemyslaw Daca, head of Polish Waters, the national water management authority, said Thursday that 10 tons of dead fish have been removed from the river."

An excerpt from a recent news article.  I don't know how or why it was done in this instance, but this is what it looks like when a body of water becomes toxic.
Now imagine you are in a country where Tyrants are trying to enslave or genocide the citizens, and it becomes obvious the value in purposefully bringing about such an event, but on a much larger scale if possible.
It would surely leave a mark.

Guerilla Warfare tactics have been used to success in certain situation for centuries now, and are mentioned in "The Art of War."  Sometimes it is the only method thay may prove effective.

I think most on here are aware that many of the scams and failed projects we see are perpetrated by the anti-crypto crowd.  The incredible and persistent effort we see put into DDOS attacks makes that pretty obvious once you connect the dots.
I am of the opinion that in fact the vast majority of such projects are derail attempts, but I wanted to see what others thought.

Global freedom in this world has reached a historical low and will likely continue to worsen rapidly.
Part of the reason for this is that until relatively recent times large areas of land had still remained unexplored and unexploited. Then a large part is due to the continuing spread of control by evil people or terrorists if you will.

If control in your country has been taken by over by an evil terrorist power you won't be able to trust your media to inform you of this as the media is one of the first venues they will have compromised.
Instead you can know by your own experiences, and watching rights being taken away, etc.

We know that the end goal of these terrorists is to enslave and genocide us.
There are various tactics that can be tried as forms of resistance.  Normal, completely peaceful forms will not be effective and are useless.
Of the tactics that may be useful I suspect that in many places Guerilla warfare, and things like sabotaging electric grids may be too difficult for many to accomplish.  
In those areas I think a more realistic form of resistance would be to concentrate on the poisoning of water supplies such as lakes and rivers.
This could slow them down buying valuable time or at the very least not allow them to get away free and clear in their commission of evil.
