Bioremediation - process(es) which includes the uses of fungi, green plants, microorganisms, and fungi to restore the environment back to its original conditional which was previously contaminated.
- What is a pest? A pest can be defined as an organism which is unwanted and/or harmful to humans. Pesticides are used to reduce pests and keep them away from crops. Because of the growing number of pests, more and more pesticides are being used everyday. Since crops are being grown all over the world, pesticides are being used all over. Insect pests have been eating and destroying the crops which forces farmers to use pesticides. From the increased use of pesticides, the environment is getting worse. Over 2.5 mllion tons of pesticides are used annually throughout the world. Pesticide use has jumped 50% since the last thirty years. However, more and more crops are lost to pests even though the toxicity is greater (organicegardeningguru). How does this make sense? THe chemical insecticides kill all insects and "pests" indiscriminately. Now that the good predator insects are killed, pests are able to reproduce and eat the crops. Less than 1% of the world's insects are considered pests. The other 99% play a pivotal role in our food chain and many are indispensable (organicegardeningguru). Moreoever, insects develop a resistance to the insecticides. Plenty of garden pests have immunity to many pesticides and cannot be get rid of. More than 500 species of pests have been recorded as resistant to the chemical insecticides (organicegardeningguru). A Cornell entomologist, Dr. David Pimental found out that pesticide use also indirectly costs the US * billion dollars a year. The pesticide is more of a problem than it was before. Many animals and good insects are being killed off by the toxins of pesticides. Humans are also getting sicknesses from ingesting remains of pesticides on fruits and vegetables. After a day of rain, pesticides also wash off from the plants and seep into the ground and drinking water.
- A few helpful tips from organicegardeningguru.com will help you decrease the damage done from pesticides:
Before You Begin
Know thy enemy. Not all garden insects are pests. Do some research to correctly identify the insect. Also, get to know its' habits and life-cycle to properly select and time treatments.
Set thresholds. Determine a level of acceptable damage. How much are you willing to put up with before seeking some sort of control? Remember: Not all pests will cause significant damage.
Watch closely. When your observations have indicated that pest levels are high enough to cause significant damage, consider treatment.
Examples -Anywhere with farmland and crops -backyards -households
Time to act. If treatment is necessary, begin with control measures that are the least harmful to beneficial insects and the environment. File:Http://www.organicgardeningguru.com/images/mixing pesticides.jpg
How Bioremediation solves the Problem There are a few solutions that can be used to solve the pesticide problem. To nature the pesticides, alkaline water and soil can be added to the sites and contamination. Another method is using fungi, bacteria, and other microorganisms to consume the pesticides as food. Moisture, temperature, aeration, pH, and the amount of organic matter are all elements that affect the success of the microorganisms. Sunlight also kills the amount of pesticides in the crop and soil.
Other Methods Other methods for cleaning pesticides include pesticide kits. There are certain chemicals to denature the pesticides. Also, pesticides need to be decontaminated from local areas that include homes and schools. [] []
Future of Bioremediation Bioremediation is a growing topic in the science world. Everyday, scientists increase the usage of bioremediation. The use of microorganisms is an effective way to clean up environmental problems. Bioremediation will be used more in the future because it is cost effective and requires less use of man made equipment. It is also safe and healthy for the environment. With pollution on the rise, bioremediation will be needed more and more to solve the pollution problems. I think it should be used more to save the planet. Since Earth is the only liveable planet, we should take care of it as best as we can.
