6 Reasons to plant trees in cities

During all these years we have gone through a time when the priority in large cities has been to build unscrupulous and without regard to sustainability reasons. This has meant that today the vast majority of cities are starting to focus their efforts on trying to reverse or mitigate many of the effects produced as a result of an uncontrolled growth.

The fact is that a single mature tree can neutralize at least 20kg of CO2 per year.

For instance, Malaga produces annually 2,250,000 tons of CO2 (one of the lowest levels in Europe). Hence the importance to create green areas, reforest, etc. It is therefore vital harvest trees, as is the means nature gives us to correct the effect of pollution.

plant trees in cities

A city where there are many parks, gardens, green areas and where you can find abundant vegetation, is synonymous of a place with good quality of life. Most of the time we are not aware of the true importance of plants for us, but this importance is increased even further in big cities, we explain why:

1. Fights the greenhouse effect

A mature tree can absorb about 20 kilos of CO2 (carbon dioxide) a year, which means that reached the 50 years that tree will absorb one ton of CO2. This is important because excess of these greenhouse gases are causing a greater impact on the climate change.

2. Prevents erosion

Soil erosion on a large scale cause very serious water pollution problems or landslides. to avoid it, planting trees is the best solution because their roots can absorb the excess of water, avoiding the water run through the land. There are species that prevent better the soil erosion such as alder, ponderosa pine or poplar.

3. Improving biodiversity

Trees are a source of food and home to many species, without them flock of birds, or insects would have no shelter. So a city will have a greater diversity, when a larger number of green areas and plants are planted.

4. Reduces pollution

Large cities tend to have very high air pollution levels, this is due to traffic, gas industries and energy consumption. Trees improve air quality that providing oxygen and moisture, while reducing urban pollution. But not only it reduces pollution of noxious gases, but also acts as a brake noise as it absorbs and blocks the noise reducing noise pollution.

5. Creating urban microclimates

A set of trees provide shade and lower the temperature in cities. You just have to go for a walk down the street in hot weather and the temperature difference in an area with trees is much cooler than an area where there is none. Trees create microclimates that help cool the atmosphere because they release water vapor into the air through their leaves. Also reducing energy expenditure and regulating the temperature of their surroundings.

6. Air Conditioning

The effect on the ecosystem a single tree is equivalent to 10 air conditioning machines working for 20 hours a day. In other words: a tree does the work that 10  air conditioning will do for a building. So plant a tree on the west side of your house (will provide shade to the house) will result in energy savings.
