Invasive species: "animals, plants or other organisms introduced by man into places out of their natural range of distribution, where they become established and disperse, generating a negative impact on the local ecosystem and species." And a 2004 paper in Diversity and Distributions that examines the terminology of invasiveness notes that there is a lack of consensus on this topic and lists five dominant definitions for 'invasive,' the most popular of which is "widespread that have adverse effects on the invaded habitat."

One time I was playing a computer game where you, the player, create the planet's ecology and are trying to make a sustainable ecological system. In this game humans are listed under “natural disaster”.
I have been thinking about our place on this planet and lately came to the conclusion that we humans are the invasive species killing off everything living on Earth.
That the planet would be better off without us.
Now, scientists say, the Earth is on the brink of a sixth “mass extinction event.” Only this time, the culprit isn’t a massive asteroid impact or volcanic explosions or the inexorable drifting of continents. It’s us.
There is plenty of information on the extent of the damage we humans have inflicted on our planet. Disappearing rain forests.
Extinction of animal species. A report by the World Wildlife Fund (WWF) has found that populations of mammals, birds, reptiles, amphibians and fish have declined on average of 52 per cent in the last 40 years.
And for freshwater creatures the situation is even bleaker, with population collapse of more than three quarters over the same period.
Almost the entire decline is down to human activity, through habitat loss, deforestation, climate change, over-fishing and hunting.
Anyone born in 1970 or before would have lived in a world teeming with animals compared to life today. http://www.telegraph.co.uk/news/earth/wildlife/11129163/Half-of-worlds-animals-have-disappeared-since-1970.html
We humans are so proud of our accomplishments...science, the arts, philosophy.
Humans are sending spaceships to other planets and are dreaming about going to the stars.
And yet we are not able to save our home planet. Selfishness, greed, ignorance, hate and apathy are ruling our species. None of these attributes are associated with other life forms on Earth.
Only humans are capable of killing their own species for so many “reasons” that are invented by humans. Religion, race, natural resources and many other excuses human species use to fight and kill each other.
We are deeply flawed creatures. Any scientific advances are being used first and foremost on inventing new ways of destruction.
There is a natural delicate ecological balance of life forms on Earth. The only exception – humans. Why are we here? Was Mother Nature aware of what will become of us humans? Do we have reason, logic and intelligence just to use it against ourselves and our planet? Is there a future for our species?
Is Darwinism working on a planetary scale?
There have got to be millions of habitable worlds even in our Galaxy. But is there a critical time in evolution when most intelligent species die out? Are we humans at that threshold presently?
There could be many causes for extinction...a killer virus, meteorites, infertility or wars.
Are we humans capable of coming to our senses and surviving?
I give us a 50/50 chance.
And if we vanish from the face of the Earth, no living thing will miss us.
