what more can you tell me about the former?

why is the peregrine falcon the fastest bird Due to its characteristic hunting stoop (high-speed dive) how fast is it? UNANSWERABLE what is its scientific name? Falco peregrinus what is its conservation status? Their population has bounced back in most parts of the world and the species is no longer at risk even in Canada where it was identified as endangered in 1978 where is it mostly found? Nearly everywhere on Earth, except extreme polar regions, very high mountains, and most tropical rainforests what kind of diet do they follow? Medium-sized birds such as pigeons and doves, waterfowl, songbirds, and waders what can you tell me about its breeding? it is sexually mature at one to three years of age, but in larger populations they breed after two to three years of age can you describe its structure ? The back and the long pointed wings of the adult are usually bluish black to slate grey with indistinct darker barring, the wingtips are black does it have any cultural significance? Yes. The Ancient Egyptian solar deity Ra was often represented as a man with the head of a Peregrine Falcon adorned with the solar disk earlier you mentioned that they were at risk on the basis of their population. was there any reason for it? The use of organochlorine pesticides, especially DDT what is its full form? Dichlorodiphenyltrichloroethane when was it initially prepared? 1874 by whom? Othmar Zeidler is it harmful to the environment? Yes. It is a persistent organic pollutant that is readily adsorbed to soils and sediments, which can act both as sinks and as long-term sources of exposure affecting organisms how is it associated with human health? It is an endocrine disruptor and is considered likely to be a human carcinogen

Endocrine disruptor [SEP] Introduction
Endocrine disruptors, sometimes also referred to as hormonally active agents, endocrine disrupting chemicals, or endocrine disrupting compounds are chemicals that can interfere with endocrine (or hormonal) systems. These disruptions can cause cancerous tumors, birth defects, and other developmental disorders. Found in many household and industrial products, endocrine disruptors "interfere with the synthesis, secretion, transport, binding, action, or elimination of natural hormones in the body that are responsible for development, behavior, fertility, and maintenance of homeostasis (normal cell metabolism)." Any system in the body controlled by hormones can be derailed by hormone disruptors. Specifically, endocrine disruptors may be associated with the development of learning disabilities, severe attention deficit disorder, cognitive and brain development problems; deformations of the body (including limbs); breast cancer, prostate cancer, thyroid and other cancers; sexual development problems such as feminizing of males or masculinizing effects on females, etc.
