Extinctionism 

The political idea held by many radicals within organizations like PETA and Green Peace that we need to work for the end of the human race. The steady attrition of humanity. The world returns to a state of nature, the balance returns.

Typical elements of the Extinctionism agenda include regulated family size, maximum birth control, maximum abortion; easy access to painless death for all who want out and veganism in the meantime. Paradise is achieved. No more human dreams. No more art or poetry. No faith, hope or love, just an environmental laboratory without scientists.

Extinction Rebellion 

A collective of people from all areas of society that are concerned for the health of our planet that you are standing on. Extinction Rebellion pressure world leaders for putting profit over the health of the Earth and do this by causing disruption in the streets as causing chaos and disruption is the only way to get the attention of our lack lustre leaders. If you oppose Extinction Rebellion and what they stand for then you are going against the health and well-being of billions who you are putting at risk.

Person 1: have you seen the extinction rebellion protest they are causing so much disruption. I hate them for getting in my way.
Person 2: Extinction Rebellion are concerned for the health of our plant and you are putting your own wealth infront of billions of lives!

Extinctual 

Unlike the Instinctual, which is an automatic response created within a species through normal evolution for the survival of the species, an extinctual response is a misguided intellectual or ignorant reaction to environmental stimuli resulting in a negative outcome for, or even possibly extinction of, the species, or the egregore of a species.
“Ingestion of harmful chemicals such as alcohol may be an extinctual response to stress”
Extinctually (adv)
