Before I started this topic for this unit my first impression of talking about biosolids for treatment of plants was disgusting. Before doing this unit I was not aware that you can use your own waste to fertilize plants. There are many pros and cons of this method of growing plants. The pros can be that it can help grow any plant needed at a faster rate and allow the plants that are being grown to have the proper nutrients its needs. Biosolids have many more pros, it can help reduce the amount of soil erosion, enrich the forest lands with the proper nutrients, protect water quality, provide topsoil, and conserve landfill spaces. If you think about it, if our human waste is being used to preserve land and be used as treatment for plants and vegitables, then that basically means that whatever is put into the grown to help the plants is what we end up consuming which then turns into a huge cycle of realeasing and consuming our own wastes. Having biosolids as a treatment for plants and soil cuts back on expensives the city has to pay on buying fertilizers and other really expensive things to help keep up with the soils. So far, it clearly shows that biosolids haven't affected humans health in anyway. Everyone is still fine, and no major diseases came from biosolids yet. Biosolid treatment is alot easier for farmers who own a farm because it allows them to make their own biosolid instead of having treatments and/ or biosolids from other parts of the country sent to them to use.
Biosolids also has it cons. People who work with the biosolids treatment have to be really carefully when they are around it. It can have diseases and can be spread unto that particular person. Biosolids should definately go through many procedures before being used, just to make sure that everything is safe and nothing wrong happens to anyone. The biosolids should be held in a place that secures the smell really well because it can he hazardous to people around it. Biosolids should be secured from faming animals just for saftey reasons.

Personally, I believe that designer babies are going too far. I believe that people shouldn't have the right to alter their child because it seems cruel. For religious people, it is against our faith. Especially in the Catholic faith. People should be able to accept their baby for the way they will be born because it gives the baby their true identity. Altering the baby takes away identity from the baby and also natural ways of life. Everyone should experience sickness, and everyone should be allowed to be who they are suppose to be. Having a baby be born the way they are suppose to be born originally allows the baby to have true real features, altering them in a lab makes them seem less real and more "computerized."
I also believe that if a embryo is being screened for any sicknesses or disease, it can be seen as a positive because then it can decrease the chances of sickness in the baby. Yet, having a embryo go through this procedure just for the fact of changing the baby cosmetically is going way to far. People should really take into consideration when they are thinking of going through a procedure like this because it has its pros and it has its cons. In the end, a pro would be for decreasing future health issues in the baby, or for allowing a baby to be altered so that it can help save another child that has a health problem. A con would be going through this process just for "wants." Meaning changing your baby because you want your baby to look or act a certain way.
