Problems Of Invasive Species

Imagine there are snakes all around you, but you don’t know it. This is what florida is like now. It's like this because people let their pet snakes go into the wild and then there are way too many snakes in the wild. Snakes are not the only invasive species there are others like foxes and medfly. Invasive species are a problem, but creative solutions are being tested. Invasive species can take over areas of the earth, and make it hard for other animals to survive. In Australia they have foxes, which are an invasive specie. Foxes are trying to kill penguins, because they are easy prey. In 2005 the small island population was 800 then went to below 10. Now we have incredibly well trained sheepdogs that protect the penguins for the enemy foxes.
One of the solutions we came up with is for penguins. A man named Swampy Marsh came up with an idea for sheep dogs to guard penguins, from the foxes. He had two guarding them and they were very good at it. Sheepdogs are a type of bread that if it knows what to protect will protect it with their lives. That is exactly what they have been doing from when they had less than 10 penguins now there's over 800. Other invasive animals need to be taken care of to, just like the python that is taking over florida. We are coming up with many solutions, but none of them are quit working. We have tried having competitions, scientists catching them, told people to report sightings, but none have completely worked. Of course we have brought down the population, but it is barely a dent. The medfly is another terrible invasive specie. They hunt down fruit farms that can have any of 250 types of fruit they will eat. They swoop in and take over. The only way we have found that works to get rid of them is quarantining the area that they are found. There are downsides to this, it costs millions of dollars a year and when they come to a fruit farm they will eat it
