This depletion, mainly due to chlorofluorocarbons (CFCs), increases UV radiation risks. However, international efforts, notably the Montreal Protocol, have reduced CFC usage and shown recovery signs in mid-latitude ozone levels, although the Antarctic hole remains an issue.

The slow metabolism and excretion of DDT lead to severe ecological consequences, including population declines in affected carnivores, as trace amounts in primary producers like plankton become exponentially concentrated as they ascend the food chain.

It explains Biochemical Oxygen Demand (BOD) related to organic matter, emphasizing the importance of keeping BOD below 1 for drinking water. The sewage treatment process includes primary, secondary, and optional tertiary treatments to reduce BOD and nutrients.

It introduces bioremediation as a pollution management method and discusses biological magnification's impact on higher trophic levels. The Love Canal disaster is highlighted as a key event that prompted the creation of the Superfund program for cleaning hazardous sites.

The human population requires resources to survive and grow, and many of those resources are being removed unsustainably from the environment. The five main threats to biodiversity are habitat loss, pollution, overexploitation, invasive species, and climate change. Increased mobility and trade has resulted in the introduction of invasive species while the other t

It highlights the significance of groundwater as a key reservoir for freshwater, vital for biodiversity and human use. The text addresses human impacts, such as extraction and land use changes, leading to increased runoff and pollution.
