Suggestion: Regular Importation

[colonyan]

Currently, carrots and chickens are making their place into the planet's ecosystem already. To increase the way the money is spent, how about making two grades of feeding materials?

Low level will act as current ones except they will be either planet's original vegetation and fauna. So carrots and chickens will move to higher tier. Higher level will be carrots and chickens and they should be obtained only through the importation and agriculture/raising using imported materials and equipment obtainable only through import.

Those new higher level feeding material could make higher plort generation and make change to see higher new more profitable variation of existing plort.
