Key Vocabulary
Endangered Species
- a species of animal or plant that is seriously at risk of extinction.
IUCN
- International Union for the Conservation of Nature.
Poaching
- illegally hunt or catch (game or fish) on land that is not one's own or in contravention of official protection.
Vulnerable Species
- A vulnerable species is a species which has been categorized by the International Union for Conservation of Nature as likely to become endangered unless the circumstances that are threatening its survival and reproduction improve. Vulnerability is mainly caused by habitat loss or destruction of the species home.
Extinction
- the state or process of a species, family, or larger group being or becoming extinct.
Wildlife
- wild animals collectively; the native fauna (and sometimes flora) of a region.
Conservation
- preservation, protection, or restoration of the natural environment and of wildlife.
Preservation
- the state of being preserved, especially to a specified degree
Flora
- the plants of a particular region, habitat, or geological period.
Fauna
- the animals of a particular region, habitat, or geological period.

Unfortunately, according to IUCN, this is true!
"To date, many species groups including mammals, amphibians, birds, reef building corals and conifers have been comprehensively assessed. As well as assessing newly recognized species, the IUCN Red List also re-assesses the status of some existing species, sometimes with positive stories to tell. For example, good news such as the downlisting (i.e. improvement) of a number of species on the IUCN Red List categories scale, due to conservation efforts. The bad news, however, is that
biodiversity is declining
. Currently, there are more than 116,000 species on The IUCN Red List, with more than 31,000 species
threatened with extinction
, including 41% of amphibians, 34% of conifers, 33% of reef building corals, 25% of mammals and 14% of birds." -

All of the above can have a hand in contributing to an animal becoming endangered, or even going extinct!
"The current extinction is most likely the result of human activity, especially over the past century. Scientists estimate that 100 to 10,000 species — from microscopic organisms to large plants and animals — go extinct each year. This is 100 to 1,000 times faster than historic extinction rates. Species can become extinct when humans over hunt and over fish, pollute the environment, destroy habitats , and introduce new species to areas." -

All of the above are threats listed by the IUCN that contribute to the endangered status of 6/7 sea turtle species in the world.
"The World Conservation Union (IUCN) has identified five major hazards to sea turtles:
Fisheries:
Sea turtles virtually everywhere are affected by fisheries, especially longlines, gill nets, and trawls. The most severe of these impacts are death after entanglement, habitat destruction and food web changes.
Direct Take:
Sea turtles and their eggs are killed by people throughout the world for food, and for products including oil, leather and shell.
Coastal Development:
Sea turtle habitats are degraded and destroyed by coastal development. This includes both shoreline and seafloor alterations, such as nesting beach degradation, seafloor dredging, vessel traffic, construction, and alteration of vegetation.
Pollution:
Plastics, discarded fishing gear, petroleum by-products, and other debris harm and kill sea turtles through ingestion and entanglement. Light pollution disrupts nesting behavior and causes hatchling death by leading them away from the sea. Chemical pollutants can weaken sea turtles’ immune systems, making them susceptible to disease.
Climate change:
Climate change will increase the frequency of extreme weather events, result in loss of nesting beaches, and cause other alterations to critical sea turtle habitats and basic oceanographic processes. It may impact natural sex ratios of hatchlings and increase the likelihood of disease outbreaks for sea turtles."
