To counter this trend, efforts are underway     3     the world to return animals and plants to certain areas.

Despite the potential concerns and risks     9    (associate) with rewilding, it is an important tool for protecting the planet and its diverse ecosystems. As such, efforts     10     be made to ensure that rewilding projects are conducted responsibly and with careful consideration of their potential impact on the environment.
