Tortoise Beetle Control: Learn How To Get Rid Of Tortoise Beetles
Clavate tortoises are one of the most endangered species in the world. They have been classified as critically endangered since 1996. According to the International Union for Conservation of Nature (IUCN), there are only around 200,000 left worldwide. Some countries such as Costa Rica, Honduras and Panama have lost all their populations of these beautiful creatures altogether! There are two main reasons why they are so rare:
1) Climate change is making them less able to survive in their native habitat due to rising sea levels.
2) Human activity is destroying their habitats, which includes burning forests and clearing land for agriculture.
These activities cause the release of large amounts of carbon dioxide into the atmosphere. This causes global warming, which in turn makes it harder for plants and animals to grow and reproduce naturally.
The last time scientists were able to count them was in 1882. Since then, they’ve gone extinct at an alarming rate. Their numbers have dropped from over 10 million back down to just under 2 million today. It’s estimated that if current trends continue, they’ll be extinct within 100 years!
Unfortunately, even though there are efforts being made to save them, they’re not getting the support that they need. Many people don’t realize that they’re close to extinction, and even those who do are frequently apathetic about helping them. If things keep going this way, clavate tortoises could soon share the fate of their cousins the Galapagos turtles, which were also driven to extinction several years ago.
Golden tortoise beetles (Charidotella egregia) are a common sight in many parts of Australia.
