There are 60 species of flightless birds walking the Earth today, but a new study reveals there would be at least four times the amount if not for human influences.

These findings were uncovered by a team at the University College of London who compiled a list of every bird species known to have gone extinct since humans appeared on the planet. They concluded how humans have influenced them, and extrapolated how many flightless birds are in existence today.

Plant and animals introduced by people to forests and other vegetation also resulted in the destruction of habitats.[/highlight]
