People in general are the cause the environment not to have the means to sustain life that it previously had to before settlers. For example, if a land that has a lot of vegetation on ground, then settlers and their farm animals come to this land and starting clear out the land. The animals will not have any more food to eat which means then they will have to go somewhere else. People need to help replant the vegetation in land that was eaten. Governments will have to get involved to help with laws and funding to help conserve lands and places to help animals to not be endangered.
There are some people that have mindset that cultural and biodiversity do not interline. People have views that the environment will adapt to the people needs which are not true. People are the one that have to adapt to the environments as the environment have been established longer than people have been alive. Every place is different when comes to the environment and people need to changes upon the environment to survive. So overall cultural diversity will change based on the biodiversity.
