Deforestation is a primary contributor to climate change, [1] [2] and climate change affects the health of forests. [3] Land use change, especially in the form of deforestation, is the second largest source of carbon dioxide emissions from human activities, after the burning of fossil fuels.
Grazing can have positive or negative effects on rangeland health, depending on management quality, [129] and grazing can have different effects on different soils [130] and different plant communities. [131] Grazing can sometimes reduce, and other times increase, biodiversity of grassland ecosystems.
The effects of climate change on human health are profound because they increase heat-related illnesses and deaths, respiratory diseases, and the spread of infectious diseases. There is widespread agreement among researchers, health professionals and organizations that climate change is the biggest global health threat of the 21st century. [1] [2]
Deforestation is defined as the conversion of forest to other land uses (regardless of whether it is human-induced). [14] Deforestation and forest area net change are not the same: the latter is the sum of all forest losses (deforestation) and all forest gains (forest expansion) in a given period. Net change, therefore, can be positive or ...
Pressures can have effects on the short run (e.g.: deforestation), or the long run (e.g.: climate change), which if known with sufficient certainty, can be expressed as a probability. They can be both human-induced, like emissions, fuel extraction, and solid waste generation, and natural processes, like solar radiation and volcanic eruptions. [1]
[243] [244] There are anecdotal reports of negative health effects on people who live very close to wind turbines. [245] Peer-reviewed research has generally not supported these claims. [246] [247] [248] Pile-driving to construct non-floating wind farms is noisy underwater, [249] but in operation offshore wind is much quieter than ships. [250]
While habitat fragmentation is often associated with its effects on large plant and animal populations and biodiversity, due to the interconnectedness of ecosystems there are also significant effects that it has on the microbiota of an environment. Increased fragmentation has been linked to reduced populations and diversity of fungi responsible ...
EcoHealth Alliance scientists are testing species for pathogens in areas with very little, moderate, and complete deforestation in order to track potential outbreaks. This data is used to promote the preservation of natural lands and diminish the negative effects of land-use change.
