1). In addition to the mobility and contamination of water, atrazine is also a potent endocrine disruptor active in the parts per billion range in fish, amphibians, reptiles, and human cell lines (Hayes et al. 1). The use of atrazine has been described by Heather Hamlin, an assistant professor with the University of Maine, School of Marine Sciences, as being responsible for a host of health problems seen in fresh water fish and amphibians (Hamlin 1). Research has shown that atrazine in water gravely affects male frogs by decreasing testosterone levels (Hayes et al.
Industrial decisions, such as the addition of lead to paints, dyes, and gasoline, have created an epidemic of lead poisonings. Lead is a naturally occurring substance and can be found in organic and inorganic forms. Lead is a reproductive toxicant detrimental to human semen quality. Decreased sperm count, motility, acid phosphatase, succinic dehydrogenase, fructose, surface reaction of sperm head DNA besides increasing abnormal sperms was reported in occupational exposure of lead in printing press workers in India. Higher lead level lowers sperm’s ability to bind and fertilize the egg.
Compared to the first two steps the last two steps of the trail look like a Matis massage. The next stage to the ritual is to inject frog poison from green tree frogs directly into the blood stream with needles made from wood. The poison is also placed onto open incisions on the skin. If the hunter does not throw up it shows great resistance and in the tribe
Fluoride’s been sold to the public as a miracle breakthrough in dental maintenance, it has jaw dropping side effects when consumed and has been added to our drinking water by the United States government. Fluoride, is a byproduct of aluminum foundries and the phosphate fertilizer industry, it is a dangerous and toxic chemical that is found in almost all pesticides, including rat poison. Yet somehow it found its way into the drinking water of over 260 million people. Paul C. Bragg, Ph.D and the author of Water: The Shocking Truth That Can Save Your Life writes in his masterpiece; “…the United States commissioned their biochemist to find a use for the sodium fluoride wastes produced by aluminum foundries… He came up with a big money-making idea: why not dissolve the stuff in drinking water? He had no medical background (pars.
Abstract Pesticides are a creation of human science designed to increase crop output. As we all know pesticides are meant to kill insects and plant disease. What many people forget is that anything that effects our environment and ecosystems, also affect our health and wellbeing. The Beneficial Poisons: Pesticides Pesticides are a serious cause for concern, but why you may ask? What is it about pesticides that makes it concerning?
2. Do background research – Utilizing at least one scholarly source, describe how variations in dissolved oxygen content in a body of water can affect fish populations. Answer = “Oxygen depletions are the most common cause of fish kills in ponds. (Aquaplant, 2014).” Based on my observation of the chart and what I read, the higher the dissolved oxygen levels the number of fish drops. Dissolved oxygen levels can also cause fish to suffocate and be more susceptible to diseases.
The areas in the greatest decline are Central America, the Caribbean, and Australia. The three primary causes for the frog decline are habitat destruction, global climate change, and a new emerging disease called chytridiomycosis (chytrid). Frogs have been given very little concern as we develop new roads, build homes, cities and industries. As a result of these cultural developments, we are destroying the frog’s habitats worldwide. Global warming and climate change have been given a lot of attention and discussion worldwide and most likely has had a significant negative effect on the frog.
These tags fool the immune system into thinking that the protein is an invader. The immune system, thinking the organism (the individual) is under attack, sends white blood cells to attack, and that triggers an allergic reaction. These reactions can range from mild to severe. Allergic responses include dermatitis, gastrointestinal and respiratory distress, including such life-threatening anaphylactic responses as biphasic anaphylaxis and vasodilation; these require immediate emergency intervention. Individuals with protein allergies commonly avoid contact with the problematic protein.
c. These pollution decline beluga’s immune system, get disease easily that linked to low birth rates of belugas which have lived in the St. Lawrence River. d. Some oil explorations such as BP oil spill destroy belugas’ habitats, too. EFFECTS of the issue. Because of these predators, humans,
The main one is the Waihole Water supply from the mountain run off, and an important system for irrigation. The state mammal of Hawaii is the monk seal. The state marine mammal is the humpback whale. Some native animal species are the Hawaiian Hoary Bat, Theridion grallator, a ‘happy face spider’. Some Invasive Animals are the Coqui frog, the Indian mongoose, and Coffee Berry Borer, which can and might destroy the coffee crops.
