Describe TWO ways the impact of humans accelerates change in an ecosystem.
![1. Along the coast of Vancouver Island in British Columbia, Canada consists of intertidal zones containing
three different species of mussels. Mussel one is tan with a spiral shaped shell and mussel two is grey
with a smooth shell. Both of these mussels have inhabited the intertidal zone for hundreds of years.
Between 1990 and 1995 a third mussel was introduced due to ship activity along the coast of the island.
To be understand the mussel population scientists collected population data from 1985 to 2005.
