One of the most practical ways to combat climate change is planting trees.
Experts estimate that 15 billion are cut down every year – and even with trees being replaced, there’s still an annual deficit of 7-10 billion. With planting being a laborious process, surely the world’s woodlands are doomed? Lauren Fletcher, thankfully, thinks not. A former NASA engineer from Nevada, Lauren, 51, has been wrestling with this issue for years. “I went to a conference on deforestation in 2009, and it really emotionally hit home,” he says. “I understood what was driving deforestation – over-logging, the cattle industry and so on – but I couldn’t understand why it was so hard to put forests back. I found out that the technology to do it fast enough wasn’t there. I thought, ‘Hey, I work for NASA! Surely there’s a way’.”
