Habitat loss

The Egyptian Tortoises are very close to extinction.  When they lose their habitat in the desert, they cannot find places to live.  Egyptian Tortoises are meant for the hot weather, and need the desert's heat.

When people build telephone poles in the desert, it creates nesting for ravens.  Ravens love to eat baby Egyptian Tortoises.  

I do not mean to sound like an environmentalist, for humans are not evil creatures.

Other reasons of endangerment are stuff like illegal pet trade (well, that's what they get for being so cute).
