Scientific data indicates that in the past 50 years humans have killed 80 % of all the wild animals of the planet, including mammals, birds, reptiles, amphibians, fish and the essential insects. This loss of animals is caused by the ignorant irresponsible human plague through 1) toxic pollution of the air, water and the earth, with climate change that is killing animals; 2) the criminal hunting and killing with extermination of wild animals; 3) the torture and killing of domestic animals for unnecessary meat consumption that destroys trees with loss of habitats and loss of biodiversity of plants and animals; each day 120 species are lost in the planet and 1,000,000 species are on the list of extinction. This massive extermination of wild animals will produce collapse of the ecosystems that will lead to human extinction before 2050. In addition, the killing of wild animals and domestic animals that are tortured and slaughtered for meat consumption releases Coronavirus, Influenza and other mortal viruses that will produce more frequent and lethal pandemics that will exterminate millions of humans within the next 30 years. If this evil irresponsible extermination of Sacred Animals continues in the next few years humanity will suffer massive exterminations and total extinction before 2050. Thus the Message to Save Humanity is summarized in the First Commandment in 3 words: Stop Killing Animals! In this memoir I present all the data on the killing of the different animals and the many specific actions that needs to be implemented to stop the destruction of the planet to arrest viral human extermination and final human extinction.
