Let’s learn about trees
These long-lived woody plants have benefits for people, animals — and the entire planet
Trees have been around for some 370 million years. These long-lived woody plants can be found on every continent except Antarctica. Scientists have identified more than 60,000 tree species. And they’ve estimated that there are 3.04 trillion individual trees growing across the globe.
Trees provide homes for animals and shade for people on hot days. One of their big benefits is that they soak up and store the greenhouse gas carbon dioxide. Some people have suggested that planting trees could help to negate the impact of global warming. Researchers last year, though, warned that the easy and simple idea wasn’t so easy and simple after all. It would be difficult to plant enough trees. However, planting trees could help — if done thoughtfully, and in the right places.
