The most often cited "greatest threat" is that of nuclear war. The so-called "nuclear winter" effect would render the planet uninhabitable for humans.
Isn't the greatest threat to the survival of the human species the human species itself? I mean, we're constantly threatening to drop bombs on other people which would inadvertently harm ourselves as well. To make a quick buck, industries that are run by people are willing to take short cuts which increase obesity, cancer, early onset of puberty, as well as any other illness one can think of. We're the greatest threat to most other organisms living on the planet and because of the things we do we're deteriorating nonliving factors like the ozone and water sources too. The list of crap we do and the crimes that we pull individually and collectively is outrageous, not to mention lethal (in most cases, eventually) Seriously, we're scary organisms.
Probably (!!!) the lost of forest drove our ancestors out of the trees and forced them to walk. The ones that got (had) a heel bone became the world's greatest striders and concurred the world.
Yes, bears are typically stronger than humans due to their larger size, muscle mass, and adaptations for survival in the wild. Their strength can vary depending on the species of bear and the individual bear itself.
Homo Sapiens is the most advanced species of human ever. Whether the others existed or not is a moot point.
The human species that appeared first on Earth is Homo habilis, followed by Homo erectus, then Homo sapiens (modern humans).
"Seres humanos" is the Spanish term for "human beings" or "human beings." It refers to individuals of the human species.
The greatest threat to biodiversity is tourist because they have to make their tourist sites so all of the trees get cut down The greatest threat to most species is in fact climate change.
probably hunters and human murders
These are factors, human or otherwise, which affect survival of a species.
Terrorist
Hackers (human) possess the greatest threat to DoD systems.Nuclear weapons.Biological weapons, especially synthetic biology.Over-crowding of animals in farms leading to the spread of epidemics.Future small-scale nano weapons that could invade our bodies.HackersHackers
The greatest threat to man's existence caused by human changes to the environment would be deforestation. This is because it releases carbon dioxide into the air, decreases oxygen, and kills organisms.
Giving out false information for the system. Humans can make errors and this can cause issues with the DoD system.
Hunting ForestryPolution
Breeding. Human population is probably the greatest single threat.
The disappearance of other species can disrupt ecosystems and negatively impact human survival. Ecosystems provide essential services like clean air, water, food, and medicine. Therefore, if other species disappear, it can ultimately threaten human well-being and survival.
Beavers are listed as Least Concern by the IUCN. Not an endangered species.
Pandas depened on human for the survival of their own kind, after all pandas are still endangered species.
