This is why ozone holes first formed, and are deeper, over Antarctica. Early models failed to take PSCs into account and predicted a gradual global depletion, which is why the sudden Antarctic ozone hole was such a surprise to many scientists. [28] [29] [30] It is more accurate to speak of ozone depletion in middle latitudes rather than holes.
Werner-Gray had a hunch that the food she was eating had caused her illnesses. "I knew it was because of my diet," she said. "Because my diet was horrendous." Rather than pursue traditional cancer ...
As to why calcium may have a protective effect against this form of cancer, Sanders said that “one theory is that the calcium may bind to free bile acids in the gut, preventing the harmful ...
For breast cancer, there is a replicated trend for women with a more "prudent or healthy" diet, i.e. higher in fruits and vegetables, to have a lower risk of cancer. [ 18 ] Unhealthy dietary patterns are associated with a higher body mass index suggesting a potential mediating effect of obesity on cancer risk.
The ozone hole was much more seen as a "hot issue" and imminent risk compared to global climate change, [13] as lay people feared a depletion of the ozone layer (ozone shield) risked increasing severe consequences such as skin cancer, cataracts, [23] damage to plants, and reduction of plankton populations in the ocean's photic zone. This was ...
There are a few reasons why some ultra-processed foods aren’t great for your health overall. “Ultra-processed foods tend to be high in sodium, sugar and fat,” Brissette says.
Climate change is altering the geographic range and seasonality of some insects that can carry diseases, for example Aedes aegypti, the mosquito that is the vector for dengue transmission. Global climate change has increased the occurrence of some infectious diseases. Infectious diseases whose transmission is impacted by climate change include, for example, vector-borne diseases like dengue ...
Ozone depletion is a separate problem caused by chlorofluorocarbons (CFCs) [233] which have been released into the atmosphere. [234] However, CFCs are strong greenhouse gases . [ 235 ] [ 236 ] Further, the hole in the ozone layer is shrinking and in 2019 was the smallest it had been since 1982, [ 237 ] [ 238 ] while global warming continues.
