Sediment erosion and land, no no tree loss

As a foreign student from a small but heavily-developed and very-over-populated country, sediment erosion seemed to be the story which can be hardly seen because most of coast is also hardened with concrete to build buildings, roads, etc.. But here in the Chesapeake Bay and its tributaries, it is occurring literally every where. 

Sediment erosion and tree loss
This is really faster than I expected. I had practiced martial art with Jeff and Dave two years ago when these trees made shadow for us.

How to save sea birds?

When I worked at Scripps Institution, Nacho (PhD student) showed me the effects of sea birds on marine ecosystem. I can't remember exactly but his study was very unique. The birds we see everyday is an important part of foodweb because it feeds on fish, crab, and clam. Also, birds may supply nutrients on the surface again by excretion which phytoplankton and bacteria can take up.

Today, for the first time, I seriously think that we all need to appreciate the friends and provide more protection after i met this bird. The bird was still alive with a heavy fishing weight in its mouth. There was nothing i can do much because i couldn't find a hook. The bird swallows the hook. Emm, i don't think I can go fishing anymore.



Rest in peace.
