Trees planting has been on the recent political agenda and manifesto with its aim to reduce carbon emissions to net zero by 2050.
Ben Macintyre, reporter for The Times, paid closer attention on the London plane tree, which he believes Britain owe a huge and often unacknowledged debt.
Plane tree has capacity to grow in the thinnest soil and to work hard to cut pollution.
Further, the protesters have been fighting the HS2 project and have seen dozens of ancient plane trees hacked down.
History had considered the planes to be too big, light-blocking and threat to the property prices. This began the start of the London chainsaw massacre in 1960s. It was driven by economic gains and aesthetic factor.
In the past London trees have been chopped under the unwarranted subsidence claims, 40% removed through insurance claims. However, Assembly’s Environmental Committee claims that only 1% was justified.
Developers are encouraged to plant broadleaf trees and consider them in their planning and new development.
Local authorities are criticised for the fact that 100,000 trees have been felled in the recent years.
It is stressed that 6 countries alone hold more than 50% of the global tree restoration potential. Russia, the US, Canada, Australia, Brazil and China.
This can be seen as a part of the larger strategies rather than a silver bullet.
There are serious implications of planting trees where they do not belong. It can kill the local ecosystem, weaken biodiversity, dry up water supplier and makes area susceptible to fires.
Japan and Ireland have already experienced the results of inadequate planting.
Plantations can not cope with the carbon uptake that goes back into the atmosphere as soon as the trees are used.
Tropical rainforests play a crucial role in the climate change. Scientist from Germany and Brazil jointly work at the Amazon Tall Tower Observatory (ATTO) allocated 325 meters above the pristine Amazon rainforest.
Andrea, director of the Max Planck Institute for Chemistrt in Mainz, Germany, is intrigued by physics and chemistry that turn water into rain clouds.
Trees release volatile organic compounds, such as isoprene and serpents, that oxidise into the tiny molecular seeds.
However, Andrea believes that there are other fast-reacting sesquiterpenes that contribute to rainforest recycling rainfall on a heroic scale.
The rainforest is important to our global climate. it makes sense to better understand the complex processes of rainforest in order to make accurate climate predictions.
Carbon dioxide, the radiation balance, fluxes of ozone and aerosols have been analysed at the ATTO.
Scientists have discovered that Amazon emits three time more isoprene than previously thought. Isoprene is one of the main precursors of ozone in the Amazon.
Water is added through the process of evapotranspiration ,and plants release water from leaves during photosynthesis. This influences climate and works as a feedback mechanism.
Deforestation and rising temperatures have been in negative synergy. The worst case scenario is that forest is progressively replaced by fire prone bush and savanna where rainfall is inhibited, the scenario of “dieback”.
Deforestation contributes to desertification, the process in which land become desert.
Social and economic pressure of exploiting natural habitats comes with global consequences.
More than 60% of anticancer drugs originate from natural sources including rainforest plants.Rainforest plants are already used to treat malaria, heart diseases, tuberculosis, diabetes, rheumatism, hypertension, bronchitis.
We can also support the Rainforest Alliance by buying products which bear the certified seal.
Rainforest is one of the best defence against climate change. It absorbs greenhouse gases from atmosphere.
It limits Earth’s reflectivity and regulates global temperatures.
Even though tropical rainforests covers less than 3% of the Earth’s area. Yet they are home to more than half of terrestrial animal species. Some of them are on the brink of extinction.
Magnificent animals to be found in rainforests are banal tigers, mountain gorillas, orangutans, jaguar, and blue poison dart frogs.
Restoring the rainforest will be expensive but it is critical to retain what is left in face of rising demand for food, fuel and land.
