Ecological imperialism is when one group of people takes over another group of people's land and resources, and uses their environment to suit their own needs. This is usually done by a more powerful group, like an empire or country, and they use their technology and resources to profit from the environment of the other group, without considering the needs and rights of the people living there. It often harms or destroys the environment of the area being taken over, and can hurt the people living in that area too.
