Help me come ideas about this topic involving nonnative species to another country?

Question Details: I have to write an essay about what we have to consider before importing nonnative speices to another country. Heres what I have so far in my Introduction.

Although importing nonnative speices such as plants with nutritious benefits and animals capable of withstanding harsh climates seem beneficial at first glance, but it could have disastrous effects. If one looks at the incidents that occured with importing nonnative speiceis it usually ended up in a disaster. Therefore, the number one thing that we should consider in importing nonnative speices is the consequences such as health hazards,........

Im stumped to come up with 3 examples of consequences. I only have one which is health hazards. Someone please help me think of 2 more consequences so that i can ahve 3 body paragraphs.

Answer 1

what about plants that deplete our rivers, lakes and even our drinking water like salt cedar(tamarix) or russian olive trees.  They are depleting our water and killing our native plants.

Answer 2

In North America there are countless non-native species which have been introduced with varying consequences, some good and some bad. Examples of  non-native species are tumble weed, carp, kudzu vine, Burmese pythons, nutria, zebra mussel, winter wheat, nile virus etc. Some consequences are lost crop and grazing land, loss of native species, nuisance, wasted resources on eradication which many times doesn't work, disease, increased food harvest, increased opportunities for hunting and fishing with the additional increased economic boon to the sporting goods industry to name just a few. Good luck on your paper.
