World’s giant trees are disappearing very quickly as forests are being attacked by the construction of roads, farms… and by pests and diseases.
While these trees used to put up with storms, pests and shor-term climate extremes, nowadays, they are more vulnerable and propitious to disappear.
William Laurance, professor at James Cook University in Cairns (Australia), declared that trees dying in forests were mostly the biggest ones.
Although giant trees just represent less than 2% of the number of trees in any forests, they contain 25% of the total biomass. Therefore, they are really important for forests’ health. This is due to the freat amount of energy theu capt and the food resource they suppose to the inhabitants of the forest.
Some reasond for their rapidly dying off are the disability of their seedlings to expand. Consequently, there won’t be young trees to replace them. Droughts are also another reason for giant trees to disappear.
As a result of all this, climate could be destabilised and global warming might increase.
However, in the article from The Guardian you can find (on the right side) a link leading to some pictures of the world’s tallest trees.
In my opinion the aim of this article is to make people aware of the consequences of building in natural ecosystems and destroying them. The environment is constantly threatende by humans which is bad for both because it contribute to our lives. There should be more protection for vast forests and not let humans destroy it. For example, in the originial article says that a highwayh has been built in the heart of the Amazon which in my opinion is the worst thing they could do. This means lots of species will disappear and biodiversity will dicrease and lead to extinction.
