Two human activities that could contribute to the introduction of invasive species.

Invasive species or alien species is the term referred to the organisms which are introduced in an ecosystem due to man made or any environmental activity. Humans play primary role in the introduction of invasive species in a certain ecosystem.

Explanation:

These activities may include the ships and boats flowing in aquatic regions of the world that carry novel aquatic organisms in their ballast water and propellers respectively. The small insects present into their shipping pallets and wooden parts are carried from one place to another place where they cause threat for the availability of food and nutrients to the already existing populations.

Another human activity that can contribute to the introduction of invasive species is the enhanced fuel consumption which leads to environmental pollution around the globe. This environmental pollution gets so immense in some areas that it can make the survival of existing species difficult and thus they move to new location for their survival.

Therefore, it can be seen that human activities have potential role in the spread and introduction of invasive species.
