S: Pesticide Use by Lydia Ji 7R
BC: The future is near, so take action and together we will be responsible for the fate of people and our world and save it by researching and studying ways to dispose pesticides in a safe manner. Thank you and I hoped you enjoyed this project! | by: Lydia
FC: Pesticide Use
1: A pesticide is a substance used for destroying insects or other organisms harmful to cultivated plants or to animals.
2: Farmers tend to use different forms of pesticides to protect their crops, while others use them to control and manage their lawns and gardens.
3: Most pesticides make 'contact' with the organisms and then the chemicals would have a effect on them that causes them to die or not want to harm the plant.
4: Different types of pesticides, herbicides,repellents and more could leave a mark on a plant and as the insect landed on it and began chewing, it would not desire to eat it anymore and instead leave and eat other plants that might give it the same ideas.
5: Methyl bromide is an odorless and colorless gas that has been used as a soil fumigant for many years in order to control pests across a wide range of agricultural sectors. | It is used in many countries by farmers before planting to get rid of all fungus, microorganisms, and weeds from the soil to avoid destruction of the crop.
6: Research shows that this pesticide was perfectly fine and good to use until they found out that this gas is destroying the ozone layer very fast. Methyl bromide is also very toxic to humans and animals. | This is why many countries and provinces, states, cities, such as Canada, members of the United Nations have banned use of this product by 2015.
7: Studies show that it will be less expensive to eliminate methyl bromide and find alternatives than to finance the medical costs associated with this increase in skin cancer caused by increased exposure to UV rays, the increase in UV radiation will cause damage and destruction to crops and it will also cause major weather changes which may lead to even more problems for the world and its people and environment. | As this graph shows, many countries used this product in the 1990s, but as we learn of the damage it can cause for everyone and many organisms, we will find other chemicals to substitute for this product and be safer and more useful.
8: Using pesticides leaves chemical residues in many bodies of water. In turn, most water in lakes, rivers, oceans and more are contaminated and may not be safe to drink and may affect the world's water supply.
9: From clean water to contaminated water, chemicals in pesticides can also travel through cracks in the ground then enter the water supply and this process of percolation would also lead to contaminated water. | CLEAN | CONTAMINATED | Leaching also may happen as soluble parts of a substance are separated out and this way, chemicals may still enter water streams and contaminate our water supply.
10: when chemicals have entered our air stream, wind may blow these chemicals everywhere including in the water where it can be harmed.
11: Some short term effects of pesticides on people can cause them to form rashes, scars, vomit, breathing difficulties and even death in extreme cases. | Some long term effects on people may be cancer, disorders to the immune system, liver and kidneys and even cause diseases and long term breathing problems such as asthma.
13: Some long term effects on the environment may be soil and water contamination, exposure to humans, and may even cause problems or deformities in nature. | Some short term effects on the environment may be that the pesticides kill beneficial soil bacteria, earthworms, snails, frogs, birds, fish, honeybees and other species that are vital to the survival of our environment..
14: To wildlife, as the chemicals are absorbed by their body, this can harm them and make them feel ill which may result in the death of many species.
15: Species that were once endangered and now have relatively large numbers may even have a sudden decrease in population as they are exposed to the chemicals in pesticides.
17: To people if pesticides continue to drain into our water supply once it is gone, people will die and that is why we need to research and produce results in the study of finding ways to dispose pesticide chemicals. | Also if they sink into our skin and harm us we may also die from this exposure unless immediate action is taken and the cure works. | These are the effects of pesticide use and how they may harm us, so together we should save all of our lives and even decrease the chance of this chemical leak into our water supply from happening again.
18: Pesticides are not that safe because instead of dissolving in an ecosystem, the waste builds up, just like in animals as the build up in their fat, when humans eat this meat, they too would be exposed to the chemicals in the pesticide. | Therefore, it is not safe to dispose of pesticides simply by burying them or dumping them into stream because they would get back to the human population and harm us and our clean water supply.
19: Incineration is very dangerous and is one of the world's only ways to dispose pesticides, but as it is harmful, society has chosen to just let the pesticides stay than put others at risk
20: In the future, everyone should stop relying on pesticides or find more safer alternatives and use them instead. This would stop the large amount of chemicals from entering our water supply and harming people and other living things. | We can also help ourselves by wearing protective clothing and gloves while dealing with pesticides and washing our hands afterwards.
21: We should also read instructions on all pesticide products so that we know how to dispose the containers and leftover products in them.
