Invasive species—organisms introduced to an environment where they are not native—pose a significant threat to biodiversity. Lacking natural predators or controls in their new habitat, these species often reproduce rapidly and outcompete native organisms for essential resources like food and light. A classic example is the Burmese python in the Florida Everglades. Originally introduced through the pet trade, these large snakes have thrived in the subtropical environment, leading to a sharp decline in native mammal populations, thereby disrupting the delicate ecological balance of the region.

Many physicists believe in determinism, which states that reality is strictly physical and everything that happens results from physical forces. But if determinism is taken as fact and not theory, the choices we make became not out own decision. Some psychologists have offered a somewhat comforting response to this hypothetical loss of free will: if we accept the concept that things are as they must be, we can reduce anxiety in out daily lives.
Text 2
When the philosophy of determinism was first standardized in the twentieth century, it was readily accepted by many within the scientific community. However, science journalist John Horgan argues that the human mind operates differently than the simplified way that scientists prefer their theories.
