*<——–Mark Rober is on the left of the picture<——–” Mark Rober is an engineer and YouTuber who make a science or chemistry video every month. He may only make 1 video per month but he puts a lot of effort and thought in his videos with some of his creations taking months to build. He was a former NASA engineer and some of his tech helped land the Curiosity Rover onto Mars. He usually makes engineering videos, explaining and detailing his creations with some videos involving chemistry. But once a year, Mark Rober tries to make a video on our environment or curing diseases without using high tech and expensive machines. For 2019, (The year that I’m in right now) He teamed up with Mr. Beast and a lot of other YouTubers to create a giant collaboration which is called TeamTrees. For his collab, his goal is to plant 20,000,000 trees before 2020. He and Mr. Beast teamed with The Arbor Day Foundation and settled on a deal, for every dollar donated to TeamTrees, a tree will be planted. His goal might be ambitious but currently, we are steadily approaching that goal with there being millions donated already. But it is already December and 2019 is going to end soon and if people don’t start donating, they might fail their goal and we might not be able to support our environment, Our planet for that matter, so donate today. Here is the TeamTrees donation page and here is his Channel Homepage: Mark Rober’s Channel Homepage:https://www.youtube.com/user/onemeeeliondollars/about TeamTrees Donation Page:https://teamtrees.org/
