Many of the world’s oldest trees, that are 100-300 years old, are dying. This is a trend happening worldwide. It’s happening in forests, savannahs, woods, mountains, cities, etc. The cause is human domination. We’ve been killing off these trees with pollution, deforestation, and other causes. This could really affect the world because other plants and animals depend on these trees for life, whether it be for food, shelter, or other needs. Large, old trees provide shelter for up to 30% of animals and birds in some ecosystems. Therefore, if these trees die out, we’d be looking at other species dying out too. It’s kind of embarrassing to see what humanity is doing to the other species of the world.

The largest living organisms on the planet, the big, old trees that harbour and sustain countless birds and other wildlife, are dying.
A report by three of the world's leading ecologists in today's issue of the journal Science warns of an alarming increase in deathrates among trees 100-300 years old in many of the world's forests, woodlands, savannahs, farming areas and even in cities.
"It's a worldwide problem and appears to be happening in most types of forest," says lead author Professor David Lindenmayer of the ARC Centre of Excellence for Environmental Decisions (CEED) and Australian National University.
"Large old trees are critical in many natural and human-dominated environments. Studies of ecosystems around the world suggest populations of these trees are declining rapidly," he and colleagues Professor Bill Laurance of James Cook University, Australia, and Professor Jerry Franklin of Washington University, USA, say in their Science report.
"Research is urgently needed to identify the causes of rapid losses of large old trees and strategies for improved management. Without… policy changes, large old trees will diminish or disappear in many ecosystems,
