Bio Solids

Poo! It smells funky and looks nasty. But the earth loves this stuff. Our sewage was is nutrient-rich organic materials when treated and processed, it can be recycled and applied as fertilizer to improve and maintain productive soils and stimulate plant growth. Commonly used on farms to help crops.

Wastewater treatmeant process? Solid, organic, and chemical waste is separated from wastewater so that it can be safely re-introduced into the ecosystem.Wastewater treatment technology has made our fresh waters safer as sources of drinking water, it has also improved marine water quality for recreation and seafood harvesting.  By treating sewage sludge, the biosolids can be used as valuable fertilizer, instead of taking up space in a landfill or other disposal facility. In many larger wastewater treatment systems, pre-treatment regulations require that industrial facilities pre-treat their wastewater to remove many hazardous contaminants. This process ensure we get safe clean water.

Biosolids completes a natural cycle in the environment. Just imagine a cow. It eats the grass, then poos, the poos used to  make new grass. Nutrients are found in biosolids, such as nitrogen, phosphorus and potassium and also minerals such as calcium, copper, iron, magnesium, manganese, sulfur and zinc, which are necessary for crop production and growth. The use of biosolids reduces the farmer's production costs and replenishes the organic matter that has been depleted over time. The organic matter improves soil structure by increasing the soil's ability to absorb and store moisture.

Biosolids are a good thing. We put waste to good use instead of leaving it out a dump and landfills. It helps in the growth of plants. Its kinda cool how our poo bloomed out greens. Biosolids should be used by everyone. It helps maintain our biodiversity by recycling.

Importance of Various Technology

Technology plays a huge part in understanding how the systems of the body work. Technology is used by everyone, but more importantly they help in the medical field. Doctors, Nurses, Specialist use these technologies to save LIVES! The technologies help them work faster and easier. From vaccines to machines. Technology plays a major role in our everyday life.
             


Vaccines are used to help strengthen our immune system. They assist our immune system in fighting harmful diseases. An example of a vaccines would be our annual flu shot. We take it every year to prevent serious flu related complications, like pneumonia. Another example of a vaccine, meningococcal injection that prevents bacterial meningitis in both children and young adults. Befroe the development of this medicine, bacterial meningitis presented physicians with many problems. In severe cases, bacterial meningitis has cause death due to rapid progression of symptoms.




Machines technology also helps in the medical field. A well known machine is the automated external defibrillator (AED). This is one of the most important machines because it assist us in regulating cardiac arrest. Without it, irreversible brain damage can occur in minutes, eventually leading to death. AEDs have become standard medical equipment in many public facilities.


Surgery, technology is most important when performing surgery. Without out we couldn't repair the bodies properly and we would have to let them suffer. Arthroscopic surgery utilizes an endoscope to examine and repair internal joints. The advantage is that a smaller incision can be made, which promotes quicker healing. Laser technology used rather than scalpel is used to cut tissue. Commonly used in operations involving the eye, such as in correcting near-sightedness and far-sightedness. Technology involving a laser scalpel can vaporize soft tissue with 
high amounts of water.

TECHNOLOGY IS BEAST! It is essential to our everyday lives. Technology has come a long way from past to present. Doctors now can save many more lives and treat illness in a highly efficient manner.

Sustainable Agriculture

Our growing population demands humanity to develop ways to increase our agriculture to meet every one's needs while minimizing impact on the environment in order to do this farms must have uniform crop types and structures and will they will rely on specific planting and harvesting dates. This will result  in a decrease of crop diversity because we are only growing highly productive crops (industrial agriculture). We will now have, a small variety of crops planted, because the less productive breeds will become extinct.

According to the united nations convention on biological diversity,  in the history of human agriculture there have been about 7000 different species of plants that have been used as food crops now because of industrial agriculture there are only about fifteen plants and eight animal species relied for about 90% of all human food

The benefits of relying on a few highly productive livestock breeds and crop varieties is that it is less costly and it provides the needs for our growing population
However every time you reduce the genetic diversity you increase the risk of the few crop varieties to survive in future conditions, such as climate change or other environmental changes.
- genetic diversity is important to withstand natural selection
- basically unsustainable human activity is the greatest threat to biodiversity
- also factory farms that have a mass production of the few selected livestock and crops force independent farms our of business and this also reduces genetic biodeversity because the other crops and livestock are no longer being tended to

- one of the problems of relying on a few highly productive livestock breeds is that because of industrial agriculture,  these livestock can no longer adapt to the natural environment and must always be carefully regulated. They are no longer able to survive outsite of the factory farm. So in the future this can become more costly
-as for the crops, when you lose genetic diversity, the few crops become more susceptible to devestation by pests. when the crops star looking the same it is easy for pests to wipe out the entire harvest compared to if all the crops were different

- overall, industrial agriculture only considers the present and not the future. by continuing industrial agriculture we are minimizing our food, livestock, and crop security in the future. Also, factory farms and industrial agriculture creates a lot of pollution which will inevitably have a major negative impact in the future.

- what we need to look towards is a sustainable agriculture which is a way of raising food that is healthy for consumers and animals and does not harm the environment. Everything is done in a humane and just way.

- all i eat for dinner and lunch is rice and chicken which is one of the main mass produced livestock and crops.
- i believe that the agricultural industry can keep up with the rapid growth of the global human population however the environment and humanity will pay a damaging price
