Find draft, grammar check, and the fourth para is my conclusion and i wrote in alternative term. Please help?

The use of herbicide in lawn care has increased in the past year. Advertising has portrayed herbicide as a magician that could provide a nice environment in a really short time, in order to fulfill our desire. This chemical spray is use to destroy needless weeds and plants, but a lot of people overuse it, and that causes many problems. These problems can typically be found around us. Pollution in our water, and other effects on human health. Therefore, we have a responsibility to prevent the use of herbicide and protect our life and the environment we live in. 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. This information reported by Rafiq Islam a soil and water specialist with Ohio State’s South Centers.

1. I found that some researches have proven that weed killer is toxic to the environment. Research is not a countable noun: I found that some research has proven or I found that some researchers have proven over-use of herbicide is directly effecting male tadpoles in the laboratory Overuse. affecting 'male tadpoles in the laboratory' - this is ambiguous; do you mean it has affected tadpoles in a laboratory, or it was discovered in a laboratory that overuse affects tadpoles? A U.S. National Cancer Institute survey - gramattically fine, but may be easier to read as: 'One U.S. National...' Now scientist had investigated organic herbicide, this organic product is vinegar. - This doesn't make sense. Perhaps you mean: 'Scientists have now investigated a type of organic herbicide, which is essentially common vinegar.' great job in killing off weeds without hurting plants, animals and human Humans (4 percent acetic acid) = (4% acetic acid) It is perfectly for farm and even home garden. = It is perfect for use on farms and even home gardens too. both human and environment = both humankind and the environment. You can find vinegar anywhere like Superstore, Safeway and Wal-mart. = ...anywhere, such as Superstore, Safeway... Wal-Mart has been rebranded as Walmart. This information reported by Rafiq Islam a soil and water specialist with Ohio State’s South Centers. Unclear what you mean, here; was all the information in the entire essay by Rafiq Islam? I don't think so. Maybe you'd be better off rearranging it slightly, so that you group Rafiq Islam's name with the information he provided, as in: Rafiq Islam reports that this is a cheap, alternative way...
2. The use of herbicides in lawn care has increased in recent years. Currently, Canadians are using approximately four million kilograms of herbicides every year. Advertising portrays herbicides as magicians that fulfill our desire for beautiful lawns in a very short time. The chemical spray is used to destroy unwanted weeds and plants. Unfortunately, many people overuse it, polluting our water and affecting our health. Therefore, we have a responsibility to prevent the use of chemical herbicides to protect our lives and the environment we live in. Herbicides contain two specific ingredients: glyphosate and 2,4D. These chemicals are commonly used on farms, parks and golf courses. Farmers and gardeners use the chemicals to kill unwanted plants, but do not realize that the chemicals do not stay on the plants. The herbicides get into our groundwater, rivers and, eventually, into the rain. [They could kill fish, beavers, frogs and birds. Do they or not? Just saying they might is not enough.] Some researchers 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 herbicides is directly affecting male tadpoles in the laboratory.

He concluded that herbicide exposure turns the tadpoles into hermaphrodites (creatures with both male and female sexual characteristics). If there are no male frogs, frogs will become extinct, and, without frogs to consume them, insect populations will increase. In fact, herbicides are not only harmful to our environment, but they are also slowly poisoning both children and adults. Children are at a higher risk of infection because a child's immune system is weaker than that of an adult. 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 at risk of developing problems from exposure to herbicides because they play on lawns, and herbicides can enter the body through the skin. According to Dr. Kelly Martin[WHO?], twenty percent of people in emergency rooms with toxic herbicide exposure are children who 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 stated that herbicides affect children’s neurological development, reproduction, growth, and the functioning of the[their?] immune and endocrine systems. 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, a scientist has investigated an organic herbicide. This organic product is vinegar. Vinegar does great job of killing weeds without harming desirable plants, animals or humans. The acidic nature of vinegar (it is four percent acetic acid) makes it an ideal organic herbicide. It works perfectly for both farms and home gardens. All that is required is a one-time application of a quart of vinegar [per X square feet] using a standard spray bottle. This is an inexpensive, non-toxic alternative herbicide that protects both humans and the environment. Vinegar can be found almost anywhere, including at Superstore, Safeway and Wal-Mart.
