week 14 homework post a brief paragraph describing why I choose my research topic

My research topic is mitochondria. The reason why I choose it is because mitochondria have their own DNA, which tells us they are genetically and ultimately not part of us.

Vaccines--how and why?

I like this one because it gives the details about the history of vaccination. The way vaccination was found is pretty immoral, but that's maybe because human rights and morality were still immature those days.

July 23 homework In your view, what more should we be doing about global warming?

Not really... we just keep going as we were. We can invest our work to new technology invention instead of doing ecological stuff like reducing CO2. It is the matter of our decision, but I would rather choose new tech development.
