Hormonal contraceptives, e.g. the pill, the patch, and the vaginal ring, contain synthetic hormones that prevent pregnancy by either stopping ovulation, changing the cervical mucus to stop sperm from passing through the cervix and finding an egg, or changing the womb's lining to prevent a fertilized egg from being implanted in it.
Seabream - university of Essex study IT appears all fish might not be equal when it comes to how they are affected by microplastics, according to new research from the University of Essex. A new study shows that within the same species of fish there are differences in how much microplastic they individually ingest. And the research found the fish which ingested the largest amount of microplastic may be more vulnerable to predators as their startle response was slower. The rising tide of plastic debris in the world’s oceans has become one of the main ecological issues of the 21st century.

Hormonal contraceptives, e.g. the pill, the patch, and the vaginal ring, contain synthetic hormones that prevent pregnancy by either stopping ovulation, changing the cervical mucus to stop sperm from passing through the cervix and finding an egg, or changing the womb s lining to prevent a fertilized egg from being implanted in it.
Despite their widespread use, hormonal contraceptives are known to increase the risk of breast cancer, which is the most common cause of cancer-related death among women worldwide, and also topped the list of most commonly diagnosed cancers in 2020.
