Only 46% of the world's reefs could be currently regarded as in good health [149] and about 60% of the world's reefs may be at risk due to destructive, human-related activities. The threat to the health of reefs is particularly strong in Southeast Asia, where 80% of reefs are endangered. By the 2030s, 90% of reefs are expected to be at risk ...
Environmental degradation is the deterioration of the environment through depletion of resources such as quality of air, water and soil; the destruction of ecosystems; habitat destruction; the extinction of wildlife; and pollution. It is defined as any change or disturbance to the environment perceived to be deleterious or undesirable.
In Canada, there is no law requiring manufacturers to state the health and environmental hazards associated with their cleaning products. Many people buy such products to support a clean and healthy home, often unaware of the product's ability to harm both their own health and the surrounding environment.
Human activity, such as fishing, mining, deforestation, etc., serves as a threat for coral reefs by affecting the niche of the coral reefs. For example, there is a demonstrated correlation between a loss in diversity of coral reefs by 30-60% and human activity such as sewage and/or industrial pollution. [41
This is an alphabetical list of environmental issues, harmful aspects of human activity on the biophysical environment. They are loosely divided into causes, effects and mitigation, noting that effects are interconnected and can cause new effects.
Human activities affect marine life and marine habitats through overfishing, habitat loss, the introduction of invasive species, ocean pollution, ocean acidification and ocean warming. These impact marine ecosystems and food webs and may result in consequences as yet unrecognised for the biodiversity and continuation of marine life forms. [3]
Biodiversity loss has bad effects on the functioning of ecosystems. This in turn affects humans, [45] because affected ecosystems can no longer provide the same quality of ecosystem services, such as crop pollination, cleaning air and water, decomposing waste, and providing forest products as well as areas for recreation and tourism. [122]
Human activities are affecting the capacity of ecosystems to provide these goods and services. [18] [19] Drivers of biodiversity loss and decline in ecosystem functioning include climate change, deforestation, desertification and land degradation, freshwater decline, overexploitation, stratospheric ozone depletion, and pollution.
