Trees may be guilty for trapping pollution in cities, a new report says. The study was done in the UK and aimed to outline how government can reduce toxic fumes and reduce their effect on public health. The scientists say that trees trap pollutants and keep them at the street level. However, a number of […]

Here at The Green Optimistic we are constantly looking for the silver lining in among all the news we sift through each day. With that in mind, let’s talk trees: According to the study of a large, interdisciplinary team of researchers, European broadleaf and coniferous trees have increased their water-use efficiency since the beginning of […]

Growing trees in urban areas is often a challenge. On one hand, the green anti-carbon-emissions weapon requires constant management and careful planning, and on the other hand, there is a direct competition for space. The latter might be a bit difficult to comprehend, as in Europe and the U.S., seeing trees being planted along sidewalks […]

A team of scientists from the University of Melbourne established that the older the tree gets, the more carbon it absorbs. The findings published in the latest issue of Nature reveal that as the years pass, an individual tree can play much more important role in the carbon cycle. With this study, the scientists were […]

Study Finds How Trees Adapt to Climate Change

Mila Luleva — Wed, 30 Jan 2013 19:31:39 +0000

Raising temperatures influence growth and health of all plant species on the planet. This has already been observed as warming has been taking place since the last Ice Age. However, recent changes have caused rapid warming and it is still unknown whether species will be able to adapt. A new study, funded by the National […]

Suzanne Simard, a professor at the University of British Columbia, reveals the latest findings in the realm of forestry. By studying the ecosystems in a forest, she and her team realized that trees actually communicate between them via underground fungi. Well, that’s not the sort of communication you’d imagine from humans, but rather a transfer […]

LED-powered Christmas Tree

Ever thought about how much electricity does your Christmas tree consume? You need not to be scarce, but think on big scale how many Christmas trees are worldwide and how much each tree consumes. Read the tree’s lighting installation booklet, and you’ll see something about 10W… Multiply these 10W by 1 billion trees, let’s say, […]

Do you agree to genetically mutate trees for ethanol production?

Ovidiu Sandru — Sun, 10 Feb 2008 13:56:21 +0000

Here we go again. A few weeks ago I wrote an article about some scientists inventing a way to modify the DNA of a bacteria to produce hydrogen. Ok, I didn’t fully agree with that – considering that bacteria is an extremely small microorganism, and you don’t know what ecological disaster it might produce when […]

We May Save The Planet If We Run Out Of Gas?

Ovidiu Sandru — Tue, 29 Jan 2008 13:54:12 +0000

Indeed, it does seem that the Earth will run out of oil, natural gas and coal much more quickly than was, originally, anticipated by researchers keeping track of overall expenditure of these resources [1]. At the same time, others warn that any expectation of nuclear power taking over as an effective substitute is both unrealistic […]
