breast implants essays

breast implants essays Breast implants, should they be made illegal or kept legal? That is the question. I personally think they should be left legal. I will tell you why, give you facts/statistics, arguments etc. about why I think that breast implants should not be illegal. The results of test and the percentages are all real. Allot of the statistics are from the worlds leading developer and manufacturer of saline and silicone filled breast implants, this is the Mcghan medical corp. In todays society, women can constantly feel the pressure of needing to look their best. Women can develop concerns over their self-image, feeling their breasts are not the right size or shape. A womens breast is fully developed by her twenties. She may have very small under developed breasts or very large breasts that cause back and neck discomfort. Other factors such as pregnancy, nursing, weight loss, age and gravity can take their toll on the appearance of womans breast adding to the concern. Cosmetic breast surgery offers many options of these concerns, with procedures that can sculpt a womans breasts to a more becoming size and shape. Breast enhancement procedures can enlarge and contour the breasts, giving a woman a shapely figure and making her more confident in her appearance. Many women experience a decrease in breast size and shape after pregnancy or with age. Sagging breasts or breast ptosis can be corrected with a breast lift and implants placement, giving firmer and younger looking breasts. Overly large breasts can be embarrassing and can also lead to skin irritation and back, neck and shoulder discomfort. Breast reduction procedures remove excess tissue, skin and fat to reshape and lift the breast. This procedure can greatly benefit women of all ages by relieving discomfort and allowing them to have a more active lifestyle. There are many options available to reconstruct the breast after mastectomy. Using implants or the...

What Makes a Marine Ecosystem

What Makes a Marine Ecosystem An ecosystem is the collection of living and non-living things in an area, and their relationship to each other. It is how animals, plants and the environment interact together and thrive. Studying ecosystems is known as ecology. A marine ecosystem is one that occurs in or near salt water and is the kind that is studied in marine biology. (Freshwater ecosystems, on the other hand, are comprised of freshwater environments such as those in rivers or lakes. Marine biologists study those types of ecosystems as well.) Because the ocean covers 71 percent of the Earth, marine ecosystems make up a large part of our planet. They vary, but all play a valuable role in the planets health, as well as the health of humans. About Marine Ecosystems Ecosystems can vary in size, but all have parts that interact with and are dependent upon each other. Upsetting one component of an ecosystem may affect other parts. If youve ever heard of the phrase ecosystem approach, it is a type of natural resource management involving making decisions regarding the whole ecosystem, rather than various parts. This philosophy realizes that everything in an ecosystem is interconnected. This is why environmentalists and marine biologists must consider entire ecosystems even though they may focus on one creature or plant in it. Everything is tied together. Protecting Marine Ecosystems Another vital reason to study ecosystems is to protect them. Humans can have significant negative impacts on our environment that can wind up destroying ecosystems and harming human health. The  HERMIONE project, a program that monitors ecosystems, notes that certain fishing practices can harm cold-water coral reefs, for example. That is a problem because the reefs support a variety of living systems including providing a home for young fish. The reefs could also be sources of potential medicines to fight cancer, which is another reason to protect them. Human impacts are ruining the reefs, which are a vital ecosystem for humans and the environment as a whole. Knowing how they function, and how to support them prior to and after components are destroyed, is imperative to assist these ecosystems. In seagrass meadows and kelp forests, for example, robust biological diversity is key to the ecosystems. In one experiment, scientists reduced the number of seaweed species. That caused the total algal biomass to decrease, which lowered the amount of food.  When scientists decreased the species that graze on microalgae that grew on seagrass, the species ate less from areas that had fewer microalgae. As a result of that, the seagrass in those areas grew slower. It affected the entire ecosystem. Experiments like this help us learn how reducing biodiversity can be extremely harmful to sensitive ecosystems.
