Science Roundup: Maggots, Alien Invaders, and More (+)

The headline really sums up these stories:

• Doctor Uses Maggots on Diabetic Sores
  
• Europeans Cigarette Packages feature grisly medical photos
  
• Court: Whales Have No Standing to Sue
  
• Washington Orca Population Heads South (I guess they didn't like the court ruling)
  

Next a story I’ve dubbed Alien vs. Predator in Vietnam and finally three different stories about alien invasions in the USA and some thoughts to ponder about.

World Health Organization (WHO) Report: Biological Predator Used to Fight Dengue Fever

Alien vs. Predator: Dengue Fever is a deadly disease spread by mosquitoes. Mesocyclops eats the Dengue Fever spreading Aedes Aegypti mosquito larvae.

One day brought the rain and the rain stayed on
And the swamp water overflowed
'skeeters and the fever grabbed the town like a fist
Doctor Jackson was the first to go

Three stories about non-native species invading and threatening the native flora and fauna.

• Relief in Chicago: No More 'Frankenfish'
  
• Group: Species Harming Lakes' Food Web
  
• Wanted: Exotic, Predator Frog in Georgia
  

Two of the stories (Frankenfish and Food Web) concern the Great Lakes and foreign species introduced by humans. The third deals with a Cuban Tree Frog that is migrating North from South Florida. Humans are probably helping the migration but then again it may natural.
Questions for you to ponder:

Should humans interfere with natural selection?
If one species threatens the survival of another should we interfere?
If the norm is for species to dominate for a time and then become extinct, then who are we to interfere with nature?

Calm down people these are rhetorical questions and not what I am advocating. Logically we should interfere because:

• Humans interfered with nature by artificially introducing the species to a new geographic region
  
• We don’t fully comprehend the ecosystem. The extinction of a "minor" species may have serious effects on us down the road. Keeping the status quo of nature is prudent for human survival

But again back to the rhetorical question. If we stumbled upon an area that humans had never been and we observed one species was on the verge of making another species extinct should we interfere with nature? Do we have the right to alter natural habitat to prevent natural selection from occurring?
