Giant trees are disappearing really fast

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.

The article is from The Guardian and the original source is the New Scientist magazine  , to read the article in the original source is necessary to subscribe to the magazine.

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.

    Les poumons de la terre près de mourir. L’asphyxiante situation que nous donne le moment critique dans lequel c’est l’ozone, la poubelle dans l’eau salée et la disparition des donneurs de l’air pur ; vraiment c’est la tragédie mondiale qui tout le monde ferme les yeux pour ne voir pas.
    Dans le Courel il y a un de ces magnifiques arbres anciens ; j’ai touché l’énorme être vif, et je m’ai dit que s’il respire pour beaucoup d’ans plus, l’espèce humaine ira pour une bonne voie… Ils font nôtre air pur, ils conforment l’air qui nous permet la vie aussi. S’ils sont tués pour les individus qui se bénéficient de son travaille sans double intention, la température prendra vitesse croissante, et nous serons perdus, comme également la planète.
    Par où est la solution ? C’est ça la chose qui nous devrons trouver. Toujours la réponse aux problèmes qui nous enferment. Un peu de travaille tous ensemble peut être suffisant, mais dans cet moment, semble que l’unique chose qu’importe dans les hautes sphères est l’économie pendant que les sujets importants sur la santé de notre planète passent à un lieu trop loin.
    Ça c’est le problème ou la vertu. Que tout est en relation !

    • Tu as raison, nous sommes perdues mais non la vie et la planète. La vie est essentiellement bactérienne dans cette planète depuis plus de 3500 million d’années, elle n’a pas besoin de nous. Non plus la planète.

  2. Good,
    – but you’d better organize the paragraphs as it seems to be a list (there are too many of them). Start with a good introductory paragraph describing the context, the present situation of the problem. Then one or two paragraphs explaining the new information given. Lastly your opinion with the conclusion.
    – remember to include an image, choose one from the link you mention (the first one is spectacular)
    – Certainly you cannot access to the article without subscribing. In these cases you can search the articles’s title in Google, somebody would have uploaded the pdf somewhere. Perhaps you’ll find something similar (try to use this as an original):
