third paragaph, grammar check?

Question

In fact, herbicide is not only harmful to our natural, but also slowly poisoning children and adults. Children always get sick easily because of their immune system is very weak so they are at the high risk level to get infected. According by a U.S. National Cancer Institute survey found that children with leukemia and asthma are 6 times more likely to come from homes that herbicide were used. Children are most at risk of developing problems because they play on lawns and herbicide can either through their skin. And according by Dr. Kelly Martin, she said 20% of the people who arrived in hospital emergency room with toxic herbicide exposure are children who’ve crawled on a lawn after it’s been sprayed safely. The Ontario College of Family Physicians, the Canadian public Health Association and the Learning Disabilities Association of Canada said ‘herbicide 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. Even adult has stronger immune system but also affecting by the chemical spray and causes sneezing, running noses, stinging eyes, headache and diarrhea. There is no such good thing about use herbicide, why government still allow people to abuse toxic

Answer 1

I can see only one paragraph. Aside from this there are several mistakes in the use of English.

Answer 2

In fact, herbicide is not only harmful to our natural ____, but also slowly poisoning children and adults. Children always get sick easily because their immune systems are very weak so they are at the high risk level to get infected. A U.S. National Cancer Institute survey found that children with leukemia and asthma are 6 times more likely to come from homes where herbicide was used. Children are most at risk of developing problems because they play on lawns and herbicide can absorb 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’ve crawled on a lawn after it’s been sprayed safely. The Ontario College of Family Physicians, the Canadian public Health Association and the Learning Disabilities Association of Canada said ‘herbicide affects 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. Even though adults have stronger immune systems they can also be affected by the chemical spray which causes sneezing, running noses, stinging eyes, headache and diarrhea. There is no good thing about herbicide use, so why does the government still allow people to abuse toxic chemicals?

That was fun. Thanks and good luck.

Answer 3

Herbicide is not only harmful to our natural habitat, but is also slowly poisoning children and adults. Children get sick easily because their immune system is very weak. Therefore they are at the high risk level to get infected.

According to a U.S. National Cancer Institute Survey it was discovered that children with leukemia and asthma are 6 times more likely to come from homes where herbicides were used.

Children are most at risk of developing such problems because they play on lawns where herbicide can permeate through their skin. According to Dr. Kelly Martin, 20% of the people who arrived in hospital emergency rooms with toxic herbicide exposure are children who’ve crawled on a lawn after it’s been sprayed with insecticides.

The Ontario College of Family Physicians, the Canadian public Health Association and the Learning Disabilities Association of Canada said ‘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. Even adults, who have stronger immune systems are also affected by chemical sprays which cause sneezing, running noses, stinging eyes, headaches and diarrhea.

The conclusion is that if there are no benefits about use of herbicides, why does government still allow people to abuse toxic substances that have these effects?

Answer 4

In fact, herbicides are not only harmful to our natural [our natural what???], 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. [NB--Don't put in quotation marks unless it's a direct quote; if it is, cite the exact source, not a group of organizations.]

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. [NB--I might move this last sentence to be in conjuction with the reference to children's immune systems above.]

There is nothing good about using herbicide [NB--not necessarily true. It does benefit the agriculture industry. Find another strong statement]; why does the government still allow people to abuse toxic
