禁止外来物种进口和买卖法律

That law is worthwhile to implement.
1. The owners’ pets don’t need to be forfeited. Only import and selling of nonnative species will be restricted.
2. The money spent in carrying out the law is much fewer than that used to remove the negative impact of nonnative species.
3. Though some animal can not breed in another country, they may carry fatal virus which can be transmitted to other animals.

The law to forbid the import and selling of nonnative species is implausible.
1. Some pet owners will be forced to turn their pet over to the authorities.
2. The law is too expensive to implement for it should examine thousands of nonnative species in US.
3. It’s unreasonable to apply one same standard to all species. Brazil rabbits can not stand the cold weather in the north so they can’t breed.
