Environment change and effects on health Flashcards
how does global environmnetal change cause skin cancer
Skin cancer can be caused by UV exposure. 90% of all non-melanoma cases are associated with UV exposure.
Skin cancer cases have increased in the 21st century, which is thought to be related to ozone depletion.
● Between 1992 - 2006, treatment of nonmelanoma skin cancers increased by nearly 77%.
The incidence of squamous cell carcinoma increased 200% over the past three decades in the US
how does global environmental change cause cataracts
● UV radiation is also thought to cause cataracts, and it is projected that cases of cataracts will continue to rise.
how does climate change cause thermal stress
As global temperatures rise, so does the prevalence and risk of intense heat waves . Overheating can cause heat stroke and other forms of hyperthermia, which can quickly become fatal. Elderly people and those subjected to high temperatures (such as those in military training) are
especially at risk.
how does climte change cause emergent and changing distribution of vector borne diseases
With climate change comes altering weather patterns and a rise
in extreme weather events . Although every disease is different, a large amount of these diseases are becoming more widely distributed, and the seasons in which they are a risk have lengthened.
Lyme disease is an example of a vector-borne disease being influenced by climate change. Lyme disease is a tick-borne disease, meaning it is carried by a tick and transferred to humans through tick bites. In North East USA especially, warmer temperatures have significantly influenced tick behavioural patterns, causing this vector-borne disease to become a greater risk to health.
how does climate change cause emergent and changing distribution of agricultural productivity
Agricultural productivity and nutritional standards : The effects of climate change (altered precipitation, altered temperatures, altered weather events etc.) will have different effects across the globe on agriculture. Some places will become more productive, others will become less productive. In areas of reduced productivity, there will be multiple negative effects on health due to lowered nutritional standards
