Question

Why is it a threat that nonnative plants are taking over native plants? What does it have to do with us, enivoment? Whats so dangerous about this?

Answer 1

Environmentalists want the widest diversity of plants possible. When an introduced plant takes over and ecosystem and edges out native plants which cannot survive we lose some of our diversity. They do not want to see 20 native plant species go extinct because one introduced plant took over.

Answer 2

It has to do with balance in nature.

Mother nature has spent millions of years getting environmental balance so that the Earth is healthy. By intentionally or accidentally importing foreign plant or other life into an environment, the balance can be thrown off so that there's a chain reaction so that parts of the environment die off.

It can work like a group of dominos falling so that vital parts disappear altogether. In the worst case, a whole biosystem can disappear. Many forms of life that have taken millions of years to develop are rapidly disappearing.

See the link below for an example of how the food chain works in nature.

Answer 3

lets take california as an example. if some people plant weird japnese trees near some of our native bushes then the trees will use up all the nuitrients in the soil and the bushes will die, while if it had been a native plant they probably would have balanced each other out.

Answer 4

native plants grow in their environment because of weather conditions, they feed the particular animals & insects of that region etc...so when foreign plants are introduced,they use water differently,dont support the animals,spread spores that may be harmful or choke the native plants out.Everything grows where it does for its special reason.If we change the natural balance...we ultimately effect our own.....
