The biggest news for the environment this week might just be that the Duke and Duchess of Cambridge took pains to add a couple of green touches to this morning's royal wedding. The flowers were seasonal, the food locally grown, and the emissions offset.

At Care2, Laura Bailey has a few more ideas for couples inclined to green a wedding: Wear a vintage wedding dress. Exchange heirloom rings. Give guests environmentally friendly wedding gifts. Ask them to donate to a charity instead of stocking your household with kitchen appliances.

Anyway…

One year after the worst oil spill in U.S. history began, key questions about its environmental impact remain unanswered. The 4.9 million barrels of BP oil that spilled into the Gulf of Mexico continue to threaten marine wildlife and other vile surprises have surfaced along the way.

Mother Jones' Kate Sheppard lists 10 reasons why we should not let the BP spill fade into the background. Perhaps the most important is the spill's effect on locals' health, about which Sheppard reports:

President Obama made an energy speech this week that had little new to offer, while on Capitol Hill, Republicans were pushing to relieve the government of its last options to limit carbon emissions. In the House, Republicans have passed a bill that would keep the EPA from regulating carbon, and in the Senate, Majority Leader Harry Reid repeatedly pushed back a vote on the same issue.

Environmental activist Tim DeChristopher was convicted yesterday of two felony counts. DeChristopher was on trial for bidding on more than 22,000 acres of public land that he could not pay for: his two crimes are making false representations to the government and interfering with the land auction.

DeChristopher made the $1.79 million bid in order to “do something to try to resist the climate crisis,” he told Tina Gerhardt, in an interview published by AlterNet. But, as Kate Sheppard explains at Mother Jones, the judge threw out “the defense that his actions were necessary to prevent environmental damage on this land and, more broadly, the exacerbataion of climate change.”

President Obama is taking heat from all sides this week for his 2012 budget proposal, which proposes increased funding for immigration enforcement and border militarization. While immigrant rights advocates are predictably up in arms over the proposal, House Republicans are (somewhat uncharacteristically) demanding significant cuts to border security funding -- on the grounds that the Obama administration’s efforts to secure the border have been ineffective and fiscally irresponsible.

Obama’s future immigration priorities remain counterproductive
