2: What are pesticides? | We all know that farmers use herbicides to control weeds and grow crops better and they use pesticides which is a product to keep bugs away from crops. If bugs got their hands on crops, they would eat it. We use insecticides spray our lawns. If you are using pesticides, you should know what they are doing to your environment.

3: How does pesticides work: Most pesticides are contact pesticides which means that in-order for the pesticides to work, it has to touch the plant and be absorbed by the outer layer.

4: Where can you find pesticide use You can find it...: -when farmers are spraying their fields to evacuate the bugs -if your parents or gardener use it

5: Short term effects of pesticides are that they can contaminate water and that can be a long term effect if kept inside too long. It can also, contaminate the soil so it will damage the next crops. It can contaminate our air when sprayed and is drifting away. Also when animals eat the crops with pesticides, they may die from the intake. | Long term effects of pesticides are the water can be contaminated. | Humans also get affected. People are having asthma, some kids have birth defects. Long term effects can be lost of IQ. You can have dizziness, headaches and etc. Also, a lot of kids are getting cancer and the cancer cell have a trace of pesticide.

6: How do pesticides affect wild life and humans? | Affects on humans: -if you live by a farm and they use pesticides, you might breath it in -The spray can drift over to where you live -it may be in the air -it might be in the water that you drink | Affects on animals: -they can drink the contaminated water -breath contaminated -eat crops with pesticides sprayed on

7: When anyone using pesticides reads the label and has proper equipment and is applied carefully and correctly it will be safe. But, it can still be harmful. It can hurt our environment and ourself. It can be spread with a lot of ways. Through the ground, in the air, in the water, through itself and other ways. It's also in the food we eat if we don't wash it properly. | How safe are pesticides?

8: Concerns about disposing: | Most people are either lazy and don't want to dump it properly or they don't know how. Most people drain or just throw it away in the nearest/biggest water source. That actually is contaminating the water. We could drink from that water, animals and waterside plants can. There are special sites for pesticide disposal. Also, you should wash your cans twice or three times and then poke holes in them.

9: What Pesticides do to the environment: Volatilization is when the vapor from the pesticides spread and drift away. It could drift to where you live and you could breath it in. That would put the pesticides in your body. That would also happen if there was spray in the air left over. That would be called spray drift. The little the pieces, the more likely they will fly away. The faster the wind, the faster it goes. This can contaminate water, humans, animals and other crops ready to harvest.

10: When pesticides are applied near slopes or hills, there can be runoff. Runoff is when pesticides slide down the hill or slope. This can contaminate water sources such as lakes, wells, ponds, and streams. The pesticides can be dissolved into water and go down the hill or be attached to soil parts. Runoff often occurs during rainfall. When the pesticide is bond to the soil it is called adsorption. Adsorption can make the soil contaminated so when you try to use it again, roots of the plant may suck in pesticides instead of just having an outer layer of it. Leaching is when pesticides are in the water underground. If you are digging underground for water or the water will lead to a stream, that water could be contaminated. Pesticides that take a while to break down may be bad. If it takes until after you have picked the plant, you could be eating it. Also, if it breaks down to quickly, it could only work for a short time. Microbial break down is when fungi or mushrooms catch the pesticides and break it down. When animals eat the mushrooms, they will be eating pesticides. Chemical break down is when the soil makes the pesticides break down. So some soils hold pesticides in them.

11: Ways to reduce Pesticide impact (If you use pesticides): -You can check the weather to make sure there will be no runoff or traveling of the pesticides. -Control how much pesticide you use and where it goes. -Don't throw your leftover pesticides into a water source. Throw them away at proper disposal sites and make sure you wash your cans before you throw them away. -Avoid using around water or where it may be harmful. -Make sure there is no wind so there is no drifting when you use it. -Make sure any equipment used is in order.
