More than one million trees have been pledged for Trump Forest, a bid by environmentalists to offset the US president’s curtailing of Obama-era clean energy initiatives by planting 10 billion trees around the globe. “US president Donald Trump doesn’t believe in the science of human-caused climate change,” reads the website for the project, launched before Trump withdrew the US from the Paris climate accord. “So we’re planting a forest to soak up the extra greenhouse gases Trump plans to put into our atmosphere. …The project was launched last March and in less than a year over a million trees have been pledged from people around the world, but particularly in the US and Europe.
