What is the reason for this huge population increase? We have a theory.
What probably caused the initial decrease was the Pinks' natural
predator, the purple algae. Most of the organisms on Heart are
microbial, including predators. Purple algae is a microorganism
that is harmful only to Pinks. Most, if not all, of Heart’s water
supply contains purple algae. This is a special kind of organism
that erodes the flesh of Pinks for nutrients. It also has the
side effect of killing the Pink host. Reds have immunity to
purple algae, and thus are not affected. However, the Pink
community was ravaged almost five hundred years ago when there was a
sudden spike in the purple algae population. To protect the
Pinks, the Reds created reservations under the surface of the
planet. These reservations were provided with a steady nutrient
supply that allowed the Pinks to be free from the purple algae.

The Reds have been heavily criticized for this, and it
raises some interesting moral questions: If a species is dying
out, who are we to say if it isn’t just the proper course of
nature? Then again, who is to say it isn’t? It is true that
if the Reds had not saved the Pinks all those years ago, they would not
be in their current ecological crises. But enough on focusing on
what they did—the goal now is to look on how to fix it.
What caused the dramatic population increase was that because purple
algae was the Pinks’ only real predator, it was the only thing keeping
the population in check. Now, the population is growing without
limit, and eventually resources will be completely depleted from the
planet. What we need to do now is figure out a solution.
The HCA has made a number of solutions
, but they all involve a significant amount of sacrifice, from both the people of Heart, and from you!
