Pollinator decline is the reduction in abundance of insect and other animal pollinators in many ecosystems worldwide that began being recorded at the end of the 20th century. Multiple lines of evidence exist for the reduction of wild pollinator populations at the regional level, especially within Europe and North America.
A study placed these causes in the order of importance as follows: "(i) habitat loss and conversion to intensive agriculture and urbanisation; ii) pollution, [32] mainly that by synthetic pesticides and fertilisers; iii) biological factors, including pathogens and introduced species; and iv) climate change." [33] Light pollution also plays a role.
The level of health risk is dependent on duration and the type and strength of irradiation. Penetrating radiation such as gamma rays, X-rays, neutrons or beta particles pose the greatest risk from an external source. Low penetrating radiation such as alpha particles have a low external risk due to the shielding effect of the top layers of skin.
Pollination is a process of moving "pollen from one flower of a species to another flower of the same species" Jay Watson a conservation biologist at the Department of Natural Resources (DNR ...
Jiří Hála claims in his textbook "Radioactivity, Ionizing Radiation and Nuclear Energy" [6] that cattle only pass a minority of the strontium, caesium, plutonium and americium they ingest to the humans who consume milk and meat. Using milk as an example, if the cow has a daily intake of 1000 Bq of the preceding isotopes then the milk will ...
[5] [6] Further problem areas are air and water pollution (including nutrient pollution), over-exploitation, invasive species [7] and climate change. [ 4 ] Many scientists, along with the Global Assessment Report on Biodiversity and Ecosystem Services , say that the main reason for biodiversity loss is a growing human population because this ...
