Invasive Species

Invasive species are living things that come from far away. They end up in a new place and cause problems. Sometimes they eat too much or push out animals that belong there. People often bring them by accident. Scientists try to control them to help nature stay balanced.

Why They Cause Trouble

Invasive species often have no predators in their new home. That means nothing stops them from growing fast. They can eat the food other animals need. Some even spread diseases. This hurts the plants and animals that already live there.

Famous Examples

Lionfish are colorful but have taken over some reefs in the Atlantic. Cane toads in Australia have hurt native animals. Kudzu is a plant that grows over everything in the southern U.S. Zebra mussels clog up pipes in American lakes. Each one shows how big the problem can be.

Fun Facts

• Kudzu can grow up to one foot in a single day.
• Burmese pythons in Florida can grow longer than a car.
• Rabbits became a huge problem in Australia after just 24 were set free.
