To add on to/be more specific with James' answer, habitat preservation means ceasing the logging of forests. Cutting down large sections of plant growth is making countless species homeless. A lot of birds of prey and big cats need large stretches of forest to hunt, so those species may end up starving to death with deforestation as well. Blocking further projects to frack, build pipelines, and disrupt marine ecosystems is also crucial.
As human populations continue to grow, we need to shift our focus to living apart from nature towards living as a part of nature. Sustainable development is a growing and essential field for the future of the human race.
Finally, more urgent climate action is necessary to protect unknown and future species. Global warming threatens biodiversity all over the world, especially in the tropics where temperatures are already at the highest end of the habitable spectrum for most biological life. If we can slow the warming of the atmosphere and the oceans, we can save more species.
