By being aware, we can each do our part to reduce our ecological footprints and help others around us reduce theirs so that we are less demanding on nature and can ensure a sustainable and happy human population over time. This concludes our lesson, and we'll be able to apply these ...
I consider whether it is meaningful to continue to talk about "population" as an issue separate from a web of interconnected factors, and whether we are in fact beyond discussions of overpopulation to the point where we have moved past and are thus over population. Alongside this topical ...

Additionally, the low NODAL environment, combined with the lack of anterior hypoblast, may contribute to the differentiation of the epiblast-like population over time. In our human embryo models with CER1-positive hypoblast, we observed a noticeable increase in primitive streak-like Brachyury ...
Our results suggest that there is currently no evidence for a persistent through-time relationship between human and megafauna population levels in North America. There is, however, evidence that decreases in global temperature correlated with megafauna population declines....
Although its population is declining worldwide, the population of the endangered species in China has grown from 150 in the 1980s to 360 at present, thanks to protection efforts over the past decades. Statistics show up to two-thirds of wild Asian elephants have wandered out of the nature re...

despite a rise in the human population. We suggest the subsequent rise was linked to increasing human influences, such as population growth and land-use changes. Our compilation suggests that the final decline occurred despite increasing air temperatures and population. We attribute this reduction in...
