Today’s world population is 7.6 billion, and the United Nations projects that by 2100, the world population will be 11.2 billion. Can the Earth’s resources feed this many people?
Alongside ethical family planning, sterilisation and vasectomy, the contraceptive should be regarded as a planet-protecting measure. One solution is the condom, a sheath-shaped barrier device, used during sexual intercourse to reduce the probability of pregnancy or a sexually transmitted infection.
Early contraceptives were biodegradable. The Egyptian Ebers Papyrus (1500 BC) describes a vaginal plug of lint, ground acacia branches and honey. Condoms, made of silk, were not always effective.
The ancient condom was found in Lund, Sweden, and is believed to have been made and used around 1640 A.D. It is made from pig intestine, although before latex, condoms made of sheepskin or intestine were not uncommon. Condoms made of dried sheep intestines were used by Roman soldiers to protect themselves during long campaigns away from home.
Neither rubber condoms which became available in 1855, nor latex condoms since the 1920s are biodegradable. About six to nine billion are sold a year. New innovations continued to occur in the condom market, with the first polyurethane condom, branded Avanti and produced by the manufacturer of Durex, introduced in the 1990s.
With the advent of AIDS (Acquired Immune Defiency Syndrome), the protective condom as mass-produced by Durex became even more popular. Worldwide condom use is expected to continue to grow: one study predicted that developing nations would need 18.6 billion condoms by 2015.
Biodegradable, latex condoms damage the environment when disposed of improperly and they also contain preservatives and hardening agents to make sure the rubber can withstand a fair amount of friction, making it harder for the condoms to break down in the landfill.
According to the Ocean Conservancy, condoms, along with certain other types of trash, cover the coral reefs and smother sea grass and other bottom dwellers. The United States Environmental Protection Agency also has expressed concerns that many animals might mistake the litter for food.
The only biodegradable condom is made of a biological material, lambskin, made from the intestinal membrane of a lamb as used by the Romans, hence non-Vegan.
One such is the “Trojan”, a brand name of condoms and sexual lubricants manufactured by the Church & Dwight Company of Ewing Township, New Jersey. Although biodegradable it does not protect against sexually transmitted infections (STIs) and HIV. (churchdwight.com)
There are other methods. In 1951, the oral contraceptive pill was invented by Gregory G. Pincus and Min Chuch Chang, biologists at the Worcester Foundation for Experimental Research, Shrewsbury, Massachusetts, in collaboration with Dr John Rock, obstetrician-gynaecologist of the Brookline Reproductive Clinic, Boston and again in collaboration with Dr Carl Djerassi of the Syntax Corporation, Mexico, who discovered the progestogenic agent, 19-Norsteroids. The US Food and Drug Administration approved “the pill” for public use in 1961, after extensive trials in Puerto Rico and Haiti.
The downside are the hormones in the pill, either progestin or a combination of progestin and synthetic estrogen, known as endocrine disruptors: women who take the pill end up passing some of them through their urine.
If they make it through the wastewater systems, the hormones can flush into rivers and streams altering fish reproductive systems and damaging ecosystem dynamics. The minipill is only made with progestin, a man-made form of the hormone progesterone made by the body.
Then there is the intrauterine device (IUD). During the late 1950s these were made of plastic with a nylon string. U.S. physician Howard Tatum’s innovation of the copper IUD in the 1960s brought with it the capital ‘T’ shaped design used by most modern IUDs. Together, Tatum and Chilean physician Jaime Zipper discovered that copper could be an effective spermicide and developed the first copper IUD, TCu200.
Not only does this contraceptive have incredible 99-plus % effectiveness, but it also requires just one small plastic T—either wrapped in copper or holding synthetic progesterone hormone—to prevent pregnancies for 3 to 12 years.
Physical waste is nearly nonexistent. Copper IUDs use up less than one tenth of an ounce (0.3 gm) of copper. Hormonal IUDs release small quantities of synthetic progesterone directly into the uterus, meaning that most of the hormone stays exactly where it is needed. In short, for the Planet, IUDs are the lesser of the three evils.
