Disruption #2: Invasive Species 1. How do humans spread invasive species? Invasive species are primarily spread by human activities, often unintentionally. People, and the goods we use, travel around the world, often carrying uninvited species with them. Ships can carry aquatic organisms into new waters. Insects can get into crates that are shipped around the world. Some decorative plants or pets can escape into the wild and become invasive. In addition, higher average temperatures and changes in rain and snow patterns caused by climate change will enable some invasive plant species to move into new areas. Insect pest infestations will be more severe as pests are able to take advantage of drought-weakened plants. Invasive species cause harm to wildlife in many ways. When a new and aggressive species is introduced into an ecosystem, it may not have any natural predators or controls. It can breed and spread quickly, taking over an area. Native wildlife may not have evolved defenses against the invader, or they may not be able to compete with a species that has no predators. Direct threats of invasive species include preying on native species, outcompeting native species for food or other resources, causing or carrying disease, and preventing native species from reproducing. There are also indirect threats of invasive species. Invasive species can change the food web in an ecosystem by destroying or replacing native food sources.

invasive species?
Invasive species are primarily spread by human

species with them. Ships can carry aquatic organisms into
new waters. Insects can get into crates that are shipped
around the world. Some decorative plants or pets can

escape into the wild and become invasive.
In addition, higher average temperatures and changes
in rain and snow patterns caused by climate change will
enable some invasive plant species to move into new
areas. Insect pest infestations will be more severe as pests
are able to take advantage of drought-weakened plants.
Invasive species cause harm to wildlife in many ways.
When a new and aggressive species is introduced into an
ecosystem, it may not have any natural predators or
controls. It can breed and spread quickly, taking over an
area. Native wildlife may not have evolved defenses
against the invader, or they may not be able to compete
with a species that has no predators.
Direct threats of invasive species include preying on
native species, outcompeting native species for food or
other resources, causing or carrying disease, and
preventing native species from reproducing. There are also
indirect threats of invasive species. Invasive species can
change the food web in an ecosystem by destroying or
replacing native food sources.
