In the fishery business, a bycatch reduction device is a tool used to help prevent catching marine animals that are not meant to be caught. This helps reduce the harmful effects of fishing on the ocean environment.
A fish gathering device (FAD) is an artificial object used to attract fish that live in open ocean areas, such as marlin, tuna, and mahi-mahi. These devices usually include floating buoys or objects attached to the ocean floor. People have used different types of FADs for many years in traditional fishing practices in regions like Island Southeast Asia (especially the Philippines), Japan, and Malta.
Sea turtles face many dangers, which have led to several species becoming endangered. There are seven species of sea turtles that still live today. Six of these belong to the family Cheloniidae, and one belongs to the family Dermochelyidae.
Ecological light pollution refers to how artificial light affects individual living things and the overall balance of ecosystems. Artificial light can have different effects on organisms. For example, it can help predators see prey more easily, but it can also cause harm or death, such as when moths are drawn to light sources and die from the heat.

A dark-sky preserve (DSP) is an area, often near a park or observatory, that limits or decreases light pollution or keeps the night sky naturally dark and protected. Different groups have used various names for these areas because they created programs independently. DarkSky International (DarkSky) uses terms like “International Dark Sky Reserve” (IDSR) and “International Dark Sky Park” (IDSP) when certifying places as dark sky areas.
DarkSky International, formerly known as the International Dark-Sky Association (IDA), is a nonprofit organization based in the United States. It was formed in 1988 by David Crawford, a professional astronomer, and Tim Hunter, a doctor and amateur astronomer. The mission of DarkSky is to protect and preserve the nighttime environment and the history of dark skies by promoting well-designed outdoor lighting.
Noise health effects are the physical and mental health problems that happen when people are regularly exposed to loud and constant sounds. Noise from traffic, in particular, is considered by the World Health Organization to be one of the most harmful environmental stressors for humans, second only to air pollution. Loud noises in workplaces or the environment can lead to hearing loss, ringing in the ears, high blood pressure, heart disease, feelings of annoyance, and trouble sleeping.
Endocrine disruptors, also called hormonally active agents, endocrine disrupting chemicals, or endocrine disrupting compounds, are chemicals that can interfere with the body’s hormonal systems. These chemicals may lead to many health problems, such as issues with sperm quality and fertility, problems with sexual organs, endometriosis, early puberty, changes in nervous system or immune function, certain cancers, breathing difficulties, metabolic issues, diabetes, obesity, heart problems, growth delays, learning disabilities, and other challenges. These chemicals are found in many household and industrial products and can mess up how hormones are made, released, used, or removed in the body.
Per- and polyfluoroalkyl substances (PFAS) are man-made chemicals with many fluorine atoms attached to a carbon chain. There are about 7 million PFAS chemicals listed in PubChem. People started using PFAS widely in 1938 when Teflon was invented.
