The world distribution and extent of forest trees are necessary to our knowledge of the biosphere. Scientists provide the first spatially continuous world map of forest tree density. This map shows that the global amount of trees is about three trillion, an order of magnitude greater than the earlier estimate. Of these trees, around 1.30 trillion live in tropical and subtropical forests, with 0.74 trillion in boreal areas and 0.66 trillion in moderate regions. Biome-level trends in tree density display climate and topography's influence in controlling local tree densities at more precise scales and humans' overwhelming effect across most countries. According to research over fifteen billion trees are cut down each year, and the world number of trees has fallen by about 46 percent since the origin of human civilization.
Plastic: the unwelcome house guest at nearly every corner of our lives — from shopping bags to footwear, coffee cups to car parts. And yet, discarded, plastic doesn't just evaporate into thin air. No, it lingers. For decades. Even centuries. According to statistics presented by Visual Capitalist , plastic daily consumer goods can break down between 20 and 600 years, depending on the composition used, how they were created, and natural elements like water and sunlight they are exposed to. Let's go deeper into why plastic takes so long to break down — and what horrid messes it leaves behind in the process. Why Plastic Isn't "Natural" — and Why That's a Problem Plastic does not naturally exist. It's a product made from petroleum and natural gas. Its long, tough carbon bonds differ from anything naturally found in ecosystems, making it extremely resistant to microbial breakdown. When we toss a plastic bottle or bag away, it's not a matter of if it will s...
