Which factor contributes to difficulties in regulating overharvesting of wild animals in developing regions?

Unsustainable Resource Use

Tropical forest logging is often unsustainable and illegal, leading to biodiversity loss. Lack of development opportunities in poor countries hinders control.
European and North American forestry practices often include planned harvests, tree replacements, and mixed forest areas to support biodiversity.
Hunting and fishing pose significant threats to wildlife populations. Overhunting occurs in developing regions, driven by poverty. Illegal wildlife trade also threatens rare species. Recreational hunting, in well-regulated areas, is less impactful.
Commercial whaling driven by demand for meat and blubber has nearly led to extinction of several species. Most countries support a ban on commercial whaling, promoting species recovery.
Overfishing depletes many fisheries, affecting commercially important species like bluefin tuna and North Atlantic cod. Overfishing disrupts marine ecosystems.
Overfishing is driven by increased demand, destructive fishing methods (like trawling), by-catches, large fishing fleets, large boats and technology, illegal fishing, and unfair fishing agreements targeting developing nations.

Sustainable Resource Management

Quotas, like those on bluefin tuna, limit harvesting.
Protected habitats (terrestrial and marine) safeguard species from overexploitation.
Monitoring and enforcement of laws (quotas, hunting seasons, minimum fish size) improve sustainability.
Afforestation and habitat restoration projects support biodiversity, creating or recovering habitats.
Aquaculture provides an alternative, reducing pressure on wild stocks, but needs environmental management.
Resource substitution promotes using less endangered species, like mackerel instead of rarer fish.
