Role of Bacteria In Our World.

Bacteria in The Environment

In the Environment, bacteria are key in keeping the cycle of life moving. There are bacteria that help to keep one of the most important elements in our world around, Nitrogen. What these bacteria do is they consume the Nitrogen that is in the air and change it into a form that plants can use. Then there are also the bacteria that help to decompose. They go in with the nitrogen cycle as well for, they put back in key nutrients for plants and animals to consume, along with Nitrogen.

Clean Up Bacteria

There are also the bacteria that can help to clean up, including the ones that help to decompose. Bioremediation is the use of bacteria and other microorganisms to change pollutants into harmless chemicals. This process is used in accidents with industrial, agricultural and municipal accidents.

Genetically Engineered Bacteria

People have been able to and have been genetically engineering bacteria for things such as medicine. It truly started when scientists inserted genes from a frog into bacteria and the bacteria produced frog genes. Now they use this method for so many more things. Scientists can engineer bacteria for things such as medicines, insecticides, cleaners, adhesives, foods and many other products besides.

Harms of Bacteria

There are many harms that bacteria cause to humans. The main on bing diseases. These are pathogenic bacteria, which cause diseases by invading a host and getting nutrients from the hosts cells. Examples of bacteria diseases are strep throat, pneumonia, Lyme disease, TB and worst of all The Plague or Black Death.

Bacteria On The Front Lines

There are bacteria that fight for us as well. They live in us in fact, fight in our body against virus's, Protists and even other bacteria!

Bacteria in the gut can unexpectedly manufacture viruses to kill off rivals during intestinal shootouts of sorts, researchers have found.These findings could help lead to new ways to kill off dangerous germs, scientists added.The average human gut is home to trillions of bacteria that outnumber human cells in the body by a factor of 10 to 1. Often these bacteria are helpful, aiding in digestion and synthesis of key vitamins.

The major war that is being fraught for human by bacteria is in the ocean. Everyday bacteria called cockolythiafors die from the hands of deadly viruses. Before they do though, they warn other bacteria around them and...breath out the air that we need. They go through this cycle of war constantly and because of this, we get half the air we breath from them.
