Some conditions that are possible reasons for declining genetic diversity of a species;
▪︎loss of habitat
▪︎inbreeding
Explanation:
Loss of habitat will definitely reduce diversity because it reduces the population size from increased competition for reduced resources. Some subspecies may be completely eliminated when their niche is completely lost.
Inbreeding also reduces diversity because it results in the expression of recessive genes in a population that are mostly disadvantageous. High inbreeding rates will result in most individuals not reaching maturity to pass down their genes to the next generations.

My guess is that fat-soluble toxins that may occur in freshwater ecosystems would most affect apex species in these ecosystems. This is because fat-soluble toxins are stored in the fat reserves of animals, and then bioaccumulate up the food chain. So in this case, most of the toxin is not secreted, but stored within the food chain, and bioaccumulates, with the concentration becoming higher the further up the food chain.
Answer:
During this time our food production has grown even faster than our population
