Oceanic Land Crab Extinction Linked to Colonization of Hawaii

A certain crab species has become extinct on the Hawaiian Islands. It has become extinct due to the colonization of humans on the island. Because land crabs play a big role in the ecosystem, this can cause harm. They were helpful with seed distribution and nutrient cycling. This species was unique to the Hawaiian Islands, so when they lost their habitats there, they could not survive.

I think humans should be careful with what they do with nature. We interfere with too many things and ruin other animals' habitats and most of us don't care. The more changes we make in these habitats, the more changes we will see, and we aren't going to like it after a while. Every small change will end up being a big one in the end. We should be more observant of what we are doing to nature and try and preserve it the way it is before we mess everything up.
