The lack of a predator lets the invader adapt to the new environment and breed without older species not dying. The environmental characteristics that could contribute to a successful invasion are no natural predators and food for the invading species. 2. Two examples of biological solutions to an invading species are and pneumonia virus for brown tree snakes and slugs that eat caulerpa taxifolia. The hazards of the pneumonia virus is that this virus would have to be engineered to pass to other snakes quickly and kill the host snake, if this process were to fail or a single snake survive then we could breed a new snake that is immune to this disease. Other problems with this solution is that once it is in the environment there is no way to really monitor how it is being transferred and how many snakes are being killed where. Another issue that comes out of this solution is that this virus
