Explanation:
This rapid population growth has an adverse effect on the natural resources and quality of life.
However, overpopulation has a deleterious effect on the environment due to the current lifestyle.
There would be rampant exploitation of natural resources, excess human waste accumulation, chances of epidemics, etc.
Besides, it would also lead to socio-economic problems like poverty, malnutrition, violence, corruption, etc.
Human overpopulation occurs if the number of people in a group exceeds the carrying capacity of the region occupied by that group.

Chromatids are only called as chromatids when they are sister chromatids, meaning that when chromosome have two double stranded DNA attached together, each of the double stranded DNA is a sister chromatid, and while the whole thing (the two sister chromatids that are attached together) is called a chromosome.
So after the DNA has been replicated, the chromosome consist of 2 sister chromatids, attached to each other at their centromere.
Overall, sister chromatid is one of the two double stranded DNA in a replicated chromosome, and chromosome is the whole "X" shape that we see. For example, in humans, after the S phase of interphase in the cell cycle, we have 46 chromosomes, with 92 chromatids, since each chromosome is an "X" shape, by having two sister chromatids.
Hope this helps!
