Approaching the end of the week for my #challengeonnaturephotography. My Day 6 photo is of the Sierra Nevada de Santa Marta in Colombia. Tropical forests are not only home to important species of plants and animals, they act as one of the world’s most important carbon sinks. Destruction of tropical forests through deforestation and degradation activities unfortunately have also rendered them into one of the world’s most important carbon sources – deforestation of tropical forests accounts for more carbon emissions than the entire global transportation sector, so efforts to tackle climate change must include enhanced efforts to engage with communities, business, and governments, to reduce these emissions, increase community and habitat protections, and improve wildlife conservation. I’m nominating Ian Redmond to this challenge as well. Ian, the challenge is to post a new photo every day for 7 days to promote wildlife conservation, and to nominate a new friend each day to do the same.
