How would sea turtles be affected by glacier melting?
The Problem: Because sea turtles use both marine and terrestrial habitats during their life cycles, the affects of climate change are likely to have a devastating impact on these endangered species. With melting polar ice caps and rising sea levels, these beaches are beginning to disappear.
Why is climate change bad for sea turtles?
Now, climate change is exposing sea turtles to even greater existential threats. Sea level rise and stronger storms will erode and destroy their beach habitats. Warming oceans will change ocean currents, potentially introducing sea turtles to new predators and harming the coral reefs some of them need to survive.
What does climate change mean for sea turtles?
Weather extremes, also linked to climate change, mean more frequent and severe storms which alter nesting beaches, cause beach erosion, and inundate, or flood sea turtle nests. Hotter sand from increasing temperatures results in decreased hatching rates or complete nest failure.
What are the main threats to sea turtles?
Expert members of the IUCN-SSC Marine Turtle Specialist Group have identified five major threats to sea turtles worldwide: fisheries bycatch, coastal development, pollution and pathogens, direct take, and climate change.
What can kill sea turtles?
To understand what really threatens sea turtle survival, we must look at the actions of humans.
- Human-Caused Threats. Harvest for Consumption.
- Illegal Sea Turtle Shell Trade.
- Commercial Fishing: Longline & Trawl.
- Marine Debris – Ingestion & Entanglement.
- Artificial Lighting.
- Coastal Armoring.
- Beach Erosion.
- Beach Activities.
How do sea turtles affect humans?
1. Sea turtles, especially green sea turtles, are one of the very few animals to eat sea grass. Without sea grass beds, many marine species humans harvest would be lost, as would the lower levels of the food chain. The reactions could result in many more marine species being lost and eventually impacting humans.
What human actions are negatively affecting sea turtles?
Along with fishing gear and climate change, there are numerous human activity threats to sea turtles. These threats include coastal development, pollution, direct harvest, invasive species and vessel strikes.
What is the biggest threat to turtles?
Sea turtles need to reach the surface to breathe and therefore many drown once caught. Incidental capture by fishing gear is the greatest threat to most sea turtles, especially endangered loggerheads, greens, and leatherbacks. This threat is increasing as fishing activity expands.
What is being done to help sea turtles?
What Can You Do to Protect Sea Turtle Habitat? Reduce marine debris that may entangle or be accidentally eaten by sea turtles. Participate in coastal clean-ups and reduce plastic use to keep our beaches and ocean clean. Trash in the ocean can harm sea turtles and other creatures that live there.
What are 3 laws protecting sea turtles?
Sea turtles are given legal protection in the United States and its waters under the Endangered Species Act (ESA), which lists the hawksbill, leatherback, Kemp’s ridley and green turtle as endangered; the loggerhead is listed as threatened. It is also illegal to import, sell, or transport turtles or their products.
Is there a fine for killing a preborn sea turtle?
They are protected under the United States Endangered Species Act of 1973 and Florida’s Marine Turtle Protection Act. Anyone who violates the Endangered Species Act by harming or killing a sea turtle could face civil penalties or criminal charges resulting in up to $50,000 in fines or up to a year in prison.
Why do humans need sea turtles?
What we do know is that sea turtles—even at diminished population levels—play an important role in ocean ecosystems by maintaining healthy seagrass beds and coral reefs, providing key habitat for other marine life, helping to balance marine food webs and facilitating nutrient cycling from water to land.
Are turtles going extinct?

How many green turtles are left in the world?
Green turtles are found throughout the world. They nest in over 80 countries and live in the coastal areas of more than 140 countries. Historically, green turtles were exploited for their fat, meat and eggs, causing global population declines….Scientific Classification.
