&gt; Each year, the medical industry catches around
&gt; 600,000 horseshoe crabs. The crabs are drained
&gt; of 30% of their blood and up to 30% of the crabs
&gt; don't live through the process. The survivors are
&gt; returned to the water, but no one really knows
&gt; how well or if they recover. In 2016, the
&gt; International Union for the Conservation of
&gt; Nature bumped the American horseshoe crab
&gt; up to vulnerable on it's red list, one step below
&gt; endangered. And the US population could keep
&gt; falling, by as much as 30% over the next 40
&gt; years.

If their blood is so precious shouldn't someone come up with a better way to harvest it that doesn't kill 1 out of every 3 of the "donors"?
