SYDNEY (AFP) - Scientists on Friday warned of an alarming increase in the death rates of the largest living organisms on the planet, the giant, old trees that harbour and sustain countless birds and wildlife.
Research by universities in Australia and the United States, published in Science, said ecosystems worldwide were in danger of losing forever their largest and oldest trees unless there were policy changes to better protect them.
