It depends on the species and its primary threats, there is no universal solution. Many South East Asian species are primarily threatened by poaching ("Empty forest syndrome"), whereas many "reptiles" and amphibians from Madagascar can apparently cope with fairly high levels of collection (e.g. Golden Mantella [Mantella aurantiaca]), while the loss of their often small habitat is the primary threat.
Answer:
Agricultural activities that cause NPS pollution include poorly located or managed animal feeding operations; overgrazing; plowing too often or at the wrong time; and improper, excessive, or poorly timed application of pesticides, irrigation water, and fertilizer. Industrial farming practices, such as monocropping and intensive tillage, have also compromised soil health over time. ... Excessive fertilizer use can also cause a buildup of salts in soil, heavy metal contamination and accumulation of nitrate (which is a source of water pollution and also harmful to humans
Explanation:

The process of independent assortment allows a species to be diverse. This process basically means that during meiosis, genes separate from one another independently :) hope this made sense
