* Kangaroo population size: The number of kangaroos varies significantly depending on location and year.
* Natural causes: Kangaroos die from natural causes like disease, old age, predation, and drought.
* Human impacts: Human activities like vehicle collisions, land clearing, and hunting also contribute to kangaroo deaths.
* Lack of consistent data: There isn't a global database that tracks kangaroo deaths on a weekly basis.
If you're interested in learning more about kangaroo conservation and threats to their population, I suggest searching for reputable sources like the Australian government's Department of Agriculture, Water and the Environment.
