Mark Zuckerberg says Donald Trump’s decision on the Paris agreement ‘puts our children’s future at risk’

Facebook CEO Mark Zuckerberg is not happy with President Donald Trump.

Trump announced Thursday that the United States would withdraw from the Paris climate agreement, an international climate accord to reduce carbon emissions.

Many folks from Silicon Valley were not pleased with the decision, including Salesforce CEO Marc Benioff and Tesla’s Elon Musk, who tweeted that he would stop advising the president as a result.

Now Zuckerberg, who made arguably his most political statement ever a week ago when he gave the commencement address at Harvard College, is also speaking out against Trump’s decision.

“Withdrawing from the Paris climate agreement is bad for the environment, bad for the economy, and it puts our children’s future at risk,” Zuckerberg wrote in a Facebook post. “For our part, we’ve committed that every new data center we build will be powered by 100% renewable energy. Stopping climate change is something we can only do as a global community, and we have to act together before it’s too late.”

Those sentiments were similar to the ones he shared at Harvard when he encouraged students to make the fight against climate change one of the millennial generation’s defining legacies.
