Atrazine causes intersex problems across many species

By

 

 There are many problems with commercial agriculture. The use of many thousands of toxic Biocides of many kinds cause deformations and malformation in many animals. These include fish amphibians, birds and people.

What kind of unintended effect are known for the herbicide Atrazine in disrupting hormone functions in animals, including Amphibians, fish, Birds and mammals?


Atrazine, an herbicide widely used in agriculture, has been studied for its potential effects on hormone function in various animals, including amphibians, fish, birds, and mammals. Here are some of the unintended effects that have been observed:

  1. Amphibians: Atrazine exposure has been linked to feminization of male frogs, leading to the development of female reproductive organs (gonadal intersex) and altered mating behaviors. It can also affect thyroid hormone levels, metamorphosis, and immune function in amphibians.

  2. Fish: Atrazine exposure in fish has been shown to disrupt the endocrine system, leading to alterations in reproductive development and function. This can include reduced fertility, skewed sex ratios, changes in gonadal morphology, and impaired reproductive behaviors.

  3. Birds: Studies have suggested that atrazine exposure can affect the reproductive system of birds. It has been associated with decreased egg production, changes in sex hormone levels, altered mating behaviors, and reduced hatching success. Additionally, atrazine exposure may impact the immune system and contribute to compromised health in birds.

  4. Mammals: While the effects of atrazine on hormone functions in mammals are less well-studied compared to amphibians, fish, and birds, some research has suggested potential impacts. Atrazine exposure has been associated with altered hormone levels, reproductive abnormalities, and adverse effects on fertility in mammals.

It's important to note that the specific effects of atrazine can vary among species, and there may be differences in sensitivity and susceptibility. Additionally, the extent of these unintended effects can depend on factors such as the dose, duration of exposure, and timing of exposure during critical developmental stages.

These findings highlight the potential risks of atrazine on the endocrine systems of various animals, raising concerns about its overall environmental impact and the need for further research and regulation.

A Simple way to Make Hot Compost Fast.

  Hot Composting.   There are three main ingredients that make a good compost. Carbon, Nitrogen and Water. Approximately one third o f each ingredient by weight . First is Carbon. T hi s can be dry leaves, grass clippings and spent garden plants or even dead weeds. Always save your leaves. Trees are deep rooted and have lots of trace minerals and carbon. Second is Nitrogen. Kitchen scraps or coffee grounds are a good source. Animal manures, like chicken, horse, cow or sheep are good. Green matter like grass clippings or green leaves, also h ave Nitrogen and are a good source. Bean or Pea vines and other legumes while still green are excellent. Third is Water. Chicken litt er is excellent for compost , it i s very high in Nitrogen, and all three of the primary nutrients, N-P-K, and contains most of the important trace minerals. Chickens are usually feed some form of calcium like oyster shell, so that they ha

       When I was young my mother and my grandmother used to make a dish from stuff that grew in the yard.  I was a budding gardener. I thought the things that they made were just regular food. They were in the traditions of my mom's family. In the desert Southwest the Native first nations and Spanish people used plants that are now considered weeds in the local diets. One was called Verdolaga, which is known as Purslane in English. It was usually lightly sauteed with onion, garlic, and tomatoes. Sometimes with hot chili put in while cooking. Usually, the Chili was on the side as another side dish. Served with beans, cheese, and tortillas.      Another local "Weed" was Lambs-quarters, Cuartos de Cordero in Spanish. Also called Wild Spinach by many people, it is quite nutritious. Prepared much the same as the Purslane. I use them still, usually only once or twice in the spring while still very tender. One of my favorites is in an omelet. Lightly sauteed with garlic an
