Nature is harsh and punishing. It sucks, and it's not just the animals we eat, is the ones we wear, is the ones that die so we can clear land, for crops or farms or cities, is the ones that cannot withstand the climate changes we created, the ones that die over the pollution we create.. The ocean for instance, it's harsh enought as it is, but we "pump" carbon dioxide and increase the temperature and coral reefs die, they die and fish and lots of invertebrates lose their homes and source of food, so many animals tangled in fishin nets and plastic, sharks getting killed cause they come too close to the shore (they do it out of desperation by the way). So many plants and anphibians, dead because of disease and pathogens that spread because of climate change, invasive species brought by us killing the native ones.
And instead of doing something about it, we are spending millions to make "direwolfs". Jarred Dimond has called the human species the Sixth great extintion of the history of our planet.
I suck and as a biology major I feel powerless about it for the most part... So I would say for me alone, a few thousand have died, for all of us millions.
People will say that's just nature, and it is partially true, but the difference between us and a lion hunting gazelle is we are very much aware of our impact, "we" just don't care for the most part... it would cost profits and be inconvenient to change things, and people's life are so miserable I think most just don't have the energy to care about much more then themselves
