Deforestation is a major contributor to climate change. [ 149 ] [ 150 ] [ 151 ] It is often cited as one of the major causes of the enhanced greenhouse effect . Recent calculations suggest that CO 2 emissions from deforestation and forest degradation (excluding peatland emissions) contribute about 12% of total anthropogenic CO 2 emissions, with ...
Methane and to a lesser extent nitrous oxide are also major forcing contributors to the greenhouse effect. The Kyoto Protocol lists these together with hydrofluorocarbon (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF 6), [43] which are entirely artificial gases, as contributors to radiative forcing.
For example, the manufacture and use of nitrogen fertilizer contributes around 5% of all global greenhouse gas emissions. [122] Livestock farming is a major source of greenhouse gas emissions. [123] At the same time, livestock farming is affected by climate change. Farm animals' digestive systems can be put into two categories: monogastric and ...
Disease burden. Disease burden is the impact of a health problem as measured by financial cost, mortality, morbidity, or other indicators. It is often quantified in terms of quality-adjusted life years (QALYs) or disability-adjusted life years (DALYs). Both of these metrics quantify the number of years lost due to disability (YLDs), sometimes ...
Alfred Nobel – founder of the Nobel Prizes. Alice Barbee Castleman – American social leader, philanthropist, and suffragist from Kentucky. Alicia Keys – American singer/songwriter; spokeswoman for Keep A Child Alive. Amal Hijazi – Lebanese singer, known for her philanthropy.
Individual action on climate change is about personal choices that everyone can make to reduce the greenhouse gas emissions of their lifestyles. Such personal choices are related to the way people travel, their diet, shopping habits, consumption of goods and services, number of children they have and so on. Individuals can also get active in ...
In particular, one major contributor to oxidative damage is hydrogen peroxide (H 2 O 2), which is converted from superoxide that leaks from the mitochondria. Catalase and superoxide dismutase ameliorate the damaging effects of hydrogen peroxide and superoxide, respectively, by converting these compounds into oxygen and hydrogen peroxide (which ...
If you have a URL (web page) link, you can add it to the title part of the citation, so that when you add the citation to Wikipedia the URL becomes hidden and the title becomes clickable. To do this, enclose the URL and the title in square brackets—the URL first, then a space, then the title. For example:
