Tornado Alley (PROG)

[janice shell]

In west africa there are probably animals and biodiversity that tolerates it's toxicity, as just about all native areas do. But in Australia it's a nasty invasive with no animals to control its growth.

NO. Castor beans and plants are deadly everywhere. Ricin is a very efficient poison. And there are toxic, but somewhat less deadly, related species, like... kidney beans. If you cook the dried ones. Do not reuse the water you soaked them in.
