"the hypothesis that bee declines are resulting from immune suppression. In 2010, a sequencing of the honey bee genome provided a possible explanation for the sensitivity of bees to pesticides. Its genome is deficient in the number of genes encoding detoxification enzymes, including cytochrome P450 monooxygenases (P450s), glutathione-S-transferases, and carboxylesterases. In 2012, researchers announced findings that sublethal exposure to imidacloprid rendered honey bees significantly more susceptible to infection by the fungus ""Nosema"", thereby suggesting a potential link to CCD, given that ""Nosema"" is increasingly considered to contribute to CCD. Neonicotinoids may interfere with bees' natural homing abilities, causing them to"

Application of pesticides to crops that are in bloom can kill honeybees, which act as pollinators. The USDA and USFWS estimate that US farmers lose at least $200 million a year from reduced crop pollination because pesticides applied to fields eliminate about a fifth of honeybee colonies in the US and harm an additional 15%. On the other side, pesticides have some direct harmful effect on plant including poor root hair development, shoot yellowing and reduced plant growth. Many kinds of animals"

Detected in the early 21st century, a threat in this direction is colony collapse disorder, a phenomenon that might foreshadow the imminent extinction of the Western honeybee. As the bee plays a vital role in pollination, its extinction would severely disrupt the food chain. An October 2017 report published in The Lancet stated that toxic air, water, soils, and workplaces were collectively responsible for 9 million deaths worldwide in 2015, particularly from air pollution which was linked to deaths by increasing susceptibility to non-infectious diseases, such as heart disease, stroke, and"

Insecticides can kill bees and may be a cause of pollinator decline, the loss of bees that pollinate plants, and colony collapse disorder (CCD), in which worker bees from a beehive or Western honey bee colony abruptly disappear. Loss of pollinators means a reduction in crop yields. Sublethal doses of insecticides (i.e. imidacloprid and other neonicotinoids) affect bee foraging behavior. However, research into the causes of CCD was inconclusive as of June 2007. Besides the effects of direct consumption of insecticides, populations of insectivorous birds decline due to the collapse"

This disorder has been attributed to - amongst other things - neonicotinoids consumed by worker bees from the extensive use of pesticides in human farming methods. Some leading scientists have advocated for the global community to designate as protected areas 30 percent of the planet by 2030, and 50 percent by 2050, in order to mitigate the contemporary extinction crisis as the human population is projected to grow to 10 billion by the middle"

Some frogs tend to be less threatened by ""Batrachochytrium dendrobatidis"" due to the variation in their physiology.

While annual losses above 30% are not out of the ordinary, the symptoms of these colony losses do not all match with those normally produced by known pests and pathogens. The amount of loss experienced as well as uncertainty around the cause of the loss lead to the coining of the term Colony Collapse Disorder (CCD) by the beekeeping community.

From 2013 the European Union restricted some pesticides to stop bee populations from declining further.

Subsidies often go towards subsidising meat production which has other nutritional and environmental implications; and it has been found that out of the $200Bn subsidies to subsidise crops from 1995–2010 around two thirds of this went to animal feed, tobacco and cotton production. On the other hand, farmers producing fruits and vegetables received no direct subsidies. The environmental impact of meat production is high due to the resource and energy requirements that go into"

However, in 16-month period from 2006 through 2007, 29% of 577 beekeepers across the United States reported CCD losses in up to 76% of their colonies. This sudden demographic loss in bee numbers is placing a strain on the agricultural sector. The cause behind the massive declines is puzzling scientists.
