Transcript of Adding Biological Agents To Help Clean Up Oil Spills


How Can It Help?
How Is It Used?
Advantages
Biological agents are effective.
Whatever pest population you want controlled will be, because the predator introduced will be naturally inclined to target the pests.
Disadvantages
You can't control whatever natural enemy you set loose in an ecosystem,
biological agents manage one pest, there is always the possibility that your predator will switch to a different crop.
Where has it been used?
Attempts to use biological warfare agents date a long time back. Scythian archers infected their arrows by dipping them in decomposing bodies or in infected blood.

Adding Biological Agents To Help Clean Up Oil Spills
Often helicopters are used to distribute dispersing agents and biological agents to clean the effected areas.
Biological agents are nutrients, enzymes, or microorganisms like fungi, yeast, or bacteria that can break down and obtain nutrients from the spilled oil.

A biological agent is also called bio-agent, biological threat agent, biological warfare, biological weapon, or bioweapon

What is a Biological Agent?
Biological agents are microorganisms that increase the rate at which natural bio degradation occurs.
Bio degradation of oil is a natural process that slowly, over the course of weeks, months, or years removes oil from the environment.
By: Brittany Kuepfer and Erin Edwards
A lot of the time, the predator that is introduced will only control the population of the pest they are meant to control.
For example if there are fruit growing around weeds, the biological agent would have no effect on the fruit but will kill the weeds.
Biological agents can be cost effective,
but it only needs to be applied once due to its self-perpetuating nature.
Biological agents take a long time to process.
They can take years to fully decompose the oil.
The process of actually setting up a biological agent system costs a lot of money
. Even though it is cheep in the long run, the process of obtaining proper biological agents and setting up the distribution is costly
Dictionary Definition- Any bacterium or virus or toxin that could be used in biological warfare

Certain biological agents can also be used to surround and isolate the oil spill in a small area so that it cannot spread.
They are an environmentally friendly alternative cleaning strategy to harsh chemicals.
Sometimes can be used to clean spilled oil off wildlife.
Biological agents can also clean, and help keep wildlife safe.
Now we can safely harness biological agents to aid the environment and keep our planet healthy.
Most oil spills over the past 10 years have been cleaned using the help of biological agents.
