Looking back at 2010, it's clear that the Gulf Oil Spill is the story that will headline environmental history books.
But it's not the only memorable one: From nearly invisible mirrored treehouses to strange pale and blind ants found in the Amazon to fake rocks that help conserve water, this year was full of surprises.
We've rounded up the most popular and memorable posts on TreeHugger in 2010, plus a look back at the year here. And check back for more -- we'll have additional Year in Review posts launching throughout the month.

Looking back at the most popular posts on TreeHugger in the Design and Architecture category, one sees a rather odd mix, barely a normal bit of design and architecture in the bunch. In fact, there is only one real building in the lot. But they do reflect the eclecticism of both our writers and our readers.
Here are some of the most popular posts of the year, selected by a mix of page views and editing for eclecticism.

Check out the top news of 2010 in the world of water.

The Year in Cars and Transportation
From a Jaguar electric car to a man single-handedly building his own subway system to a tiny, tiny RV, and more, the following 10 stories were the most popular -- according to traffic -- in the transportation category.

From sexy Leo's mega donation to tigers to Kevin Costner's surprise knowledge of oil clean-up technology, celebrities were on fire this year. There were a few mistakes, however....such as NBC's "Tonight Show" debacle, which sent a barely used set to landfill.
Here's a look back at the year in green hits and misses when it comes to Hollywood's A-listers.

We wish we could say the BP oil spill in the Gulf of Mexico was the only horrific environmental disaster this year.
From red toxic sludge spewing through Hungary to floods in Pakistan and heatwaves in Russia, 2010 was a year of record-setting natural disasters -- all of which were exacerbated by climate change.
As part of our Year in Review Series, here's a sobering look back at the year's worst environmental catastrophes.

Our top 10 posts in this category also include really, really ugly fish, whales that eat golf balls, boob-shaped clouds, and more.
The Year in Extinct Animals That Returned From the Dead

According to some estimates, a species is lost every 20 minutes. This shocking number considers factors like habitat loss but also includes approximations of the planet's total number of species, known and unknown.
Actually declaring a species extinct, however, is a long and laborious process that requires evidence beyond a reasonable doubt the plant or animal has disappeared from the face of the earth. The difficulty of this process is highlighted by the fact that only 875 extinctions have been officially documented since 1500.
And a few of those 875 have made miraculous reappearances.
