Herbicide contains two specific ingredients: glyphosate and 2,4D. These chemicals are commonly used in farms, parks and golf courses. Farmers and gardeners use the chemicals to kill unwanted plants, but they don’t realize that the chemicals do not stay on the plants. The herbicides are getting into our water, rivers and, subsequently, into the rain. It could kill fish, beavers, frogs and birds.
I found that some researches have proven that weed killer is toxic to the environment. John Struger, a scientist at the Canadian Centre for Inland Waters, analyzed urban streams and detected nine types of herbicides. Tyrone Hayes, the developmental endocrinologist at the University of California at Berkeley, said that over-use of herbicide is directly effecting male tadpoles in the laboratory. He tested the level used in the environment, and found that this chemical removed the testicles of male tadpoles, and prevented male characteristics from fully forming. He concluded that herbicide exposure turns the tadpoles into hermaphrodites (creatures with both male and female sexual characteristics). If there are no more male frogs, frog populations will decrease, and, without the frogs to consume them, bug populations will increase.

In fact, herbicides are not only harmful to our environment but are also slowly poisoning both children and adults. Children are at a high risk of infection because their immune systems are very weak. A U.S. National Cancer Institute survey found that children with leukemia and asthma are six times more likely to come from homes where herbicides were used. Children are most at risk of developing problems because they play on lawns, and herbicides can enter through their skin. And according to Dr. Kelly Martin, 20% of the people who arrive in hospital emergency rooms with toxic herbicide exposure are children who have crawled on a lawn after it had been sprayed safely. The Ontario College of Family Physicians, the Canadian Public Health Association and the Learning Disabilities Association of Canada have said that herbicides affect children’s neurological development, reproduction, growth, and the functioning of the immune and endocrine systems. Moreover, Canadians are using approximately four million kilograms of herbicides every year. Adults have stronger immune systems, but are also affected by the chemical sprays, exhibiting symptoms such as sneezing, running nose, stinging eyes, headache and diarrhea.

Now scientist had investigated organic herbicide, this organic product is vinegar. Vinegar does great job in killing off weeds without hurting plants, animals and human. The acidic nature of vinegar (4 percent acetic acid) is what makes it an ideal organic herbicide. It is perfectly for farm and even home garden. All you need to do is make a one-time application of a quart of vinegar using a standard spray bottle. This is a cheap alternative way to protect both human and environment. You can find vinegar anywhere like Superstore, Safeway and Wal-mart.

i thnk i need a better conclusion

u might want to check this sentence: *Pollution in our water, and other effects on human health.
in this sentenec: *Tyrone Hayes, the developmental endocrinologist at the University of California at Berkeley, said that *over-use* of herbicide is directly *effecting*male tadpoles in the laboratory. , i don’t think over-use needs a hyphen. and it should be affecting not effecting
in this part: Now *scientist* had investigated organic herbicide, it should be either scientists or a scientist
u should check this sentence: Now scientist had investigated organic herbicide, this organic product is vinegar. i think it should be a period instead of a comma.
in this part: Vinegar does *great job in* killing off weeds without hurting plants, animals and human. it think u should say *a great job of

sorry if i critized too much….. it really a good conclusion
good luck i hope i helped

Other than the smell, application was easy, and for a first time it looked pretty good.

Any questions just comment
