Know : 22 Reasons : Why We Need Trees?

Trees combat the climate change


Excess carbon dioxide (CO2) caused by many factors is a building up in our atmosphere and contributing to climate change. Trees absorb CO2, removing and storing the carbon while releasing the oxygen back into the air. In one year, an acre of mature trees absorbs the amount of CO2 produced when you drive your car 26,000 miles.

Trees clean the air


Trees absorb odors and pollutant gases (nitrogen oxides, ammonia, sulfur dioxide and ozone) and filter particulates out of the air by trapping them on their leaves and bark.

Trees provide oxygen


In one year an acre of mature trees can provide enough oxygen for 18 people.

Trees cool the streets and the city


Average temperatures in Los Angeles have risen 6°F in the last 50 years as tree coverage has declined and the number of heat-absorbing roads and buildings has increased.
Trees cool the city by up to 10°F, by shading our homes and streets, breaking up urban “heat islands” and releasing water vapor into the air through their leaves.

Trees conserve energy


Three trees placed strategically around a single-family home can cut summer air conditioning needs by up to 50 percent. By reducing the energy demand for cooling our houses, we reduce carbon dioxide and other pollution emissions from power plants.

Trees save water


Shade from trees slows water evaporation from thirsty lawns. Most newly planted trees need only fifteen gallons of water a week. As trees transpire, they increase atmospheric moisture.

Trees help prevent water pollution

Trees cleans water

Trees reduce runoff by breaking rainfall thus allowing the water to flow down the trunk and into the earth below the tree. This prevents stormwater from carrying pollutants to the ocean. When mulched, trees act like a sponge that filters this water naturally and uses it to recharge groundwater supplies.

Trees help prevent soil erosion


On hillsides or stream slopes, trees slow runoff and hold soil in place.

Trees shield children from ultra-violet rays

Skin cancer is the most common form of cancer in the United States. Trees reduce UV-B exposure by about 50 percent, thus providing protection to children on school campuses and playgrounds – where children spend hours outdoors.

Trees provide food

An apple tree can yield up to 15-20 bushels of fruit per year and can be planted on the tiniest urban lot. Aside from fruit for humans, trees provide food for birds and wildlife.

Trees heal

Studies have shown that patients with views of trees out their windows heal faster and with less complications. Children with ADHD show fewer symptoms when they have access to nature. Exposure to trees and nature aids concentration by reducing mental fatigue.

Trees reduce violence

Tree reduces violence

Neighborhoods and homes that are barren have shown to have a greater incidence of violence in and out of the home than their greener counterparts. Trees and landscaping help to reduce the level of fear.

Trees mark the seasons

Is it winter, spring, summer or fall? Look at the trees.

Trees create economic opportunities


Fruit harvested from community orchards can be sold, thus providing income. Small business opportunities in green waste management and landscaping arise when cities value mulching and its water-saving qualities. Vocational training for youth interested in green jobs is also a great way to develop economic opportunities from trees.

Trees are teachers and playmates


Whether as houses for children or creative and spiritual inspiration for adults, trees have provided the space for human retreat throughout the ages.

Trees bring diverse groups of people together


Tree plantings provide an opportunity for community involvement and empowerment that improves the quality of life in our neighborhoods. All cultures, ages, and genders have an important role to play at a tree planting or tree care event.

Trees add unity

Trees as landmarks can give a neighborhood a new identity and encourage civic pride.

Trees provide a canopy and habitat for wildlife


Sycamore and oak are among the many urban species that provide excellent urban homes for birds, bees, possums and squirrels.

Trees block things


Trees can mask concrete walls or parking lots, and unsightly views. They muffle sound from nearby streets and freeways, and create an eye-soothing canopy of green. Trees absorb dust and wind and reduce glare.

Trees provide wood

In suburban and rural areas, trees can be selectively harvested for fuel and craft wood.

Trees increase property values


The beauty of a well-planted property and its surrounding street and neighborhood can raise property values by as much as 15 percent.

Trees increase business traffic


Studies show that the more trees and landscaping a business district has, the more business will flow in. A tree-lined street will also slow traffic – enough to allow the drivers to look at the store fronts instead of whizzing by.

Must read Story : Mineral Water and Roasted Cockroach


Whenever a waiter forces you to go for a bottled water in any restaurant, especially in India, please remember this story. Mineral water and Roasted Cockroach

LIMITED MEALSI was so hungry; lunch time, I entered just another restaurant you can find on a busy street of any Indian cities. I ordered for a typical South Indian Rice meal. Within minutes a plate of meals arrived with small Katoris (small steel bowls) filled with a variety of gravy and side dishes.

“Bon Appetit” eagerly I started mixing the rice with Sambar (default gravy served with rice) and started eating. My bad luck, it was very spicy. I searched for water and could not find it.

“Excuse me! Water!” waved my hands to a nearby waiter.

“Hey! Don’t you keep water first?” He yelled at another waiter who handled his table. The other guy rushed with a glass of water.

I was about to drink and it was so dirty! Some kind of oily stuffs floating on the surface of the water. I was puzzled to whether drink it or not. The waiter could see the question on my face “Sir, may I bring a water bottle?”

The chillies were doing the work, so I asked him to bring it faster. The waiter immediately brought a mineral water bottle from the counter and gave it. He took back the oily glass of water and kept it in a tray, shouting “Table no.7 one mineral water”.

I was then relaxed. I wondered why the waiter has not asked any apologies for serving me a dirty water or tried to bring another glass of clean water to drink. I followed the waiter’s ‘by then’ actions. The glass of water served to me was still there, ready to be served to a next person, it seems.

There came another victim from a gang of college students, asked for a glass of water. I was shocked with what happened next. The waiter served the same glass of water, what he tried to serve me earlier.

His gamble worked, a guy noticed it was dirty to drink and asked why it was like that and the waiter said “Sorry, may I give you some bottle water?” and the guys nodded. That’s sale no. 2 since my arrival. The dirty glass went back to the same place.

I understood that everything was a pure sales trick to force the customers to buy bottled water. Sadly, there are a few who chose to drink that dirty water, they might not have noticed or do not want to afford for a water bottle. In fact not everyone can afford a water bottle all the time.

“How can they cheat customers like this?” I decided to question the waiter or the restaurant owner about this. I could not eat any more and was about to leave the table to rebuke the restaurant people.

“Hey! Hey! Do not eat this meal… Look! There is a cockroach in the food!” One of the college guys screamed.

Soon the rest of other customers gathered around their table, so do I. The restaurant manager rushed there and asked apologies to the students after confirming the roasted Cockroach in the food.

The college guys have taken snaps of that and threatened to lodge a complaint against the restaurant, legally. The Manager pleaded for mercy as the other customers went furious. At last after his continuous begging for pardon, they warned him that it should not be repeated, else they will post the photos of the cockroach with the restaurant name on Facebook and take legal action. They asked the manager to give that commitment as a written letter to provide clean food and water. The manager agreed with no option.

They got the signature from the other customers, including me as a witness to this incident. Slowly the customers walked out without paying anything.

I walked along with the college guys.

“Hey guys, I was thinking that you too were fooled by the waiter, just like me, when he made you buy the mineral water. I thought of questioning that manager about the dirty water, but before that this cockroach thing popped up! Even the mineral water they sold to us was a part of their trick, you know that?”

“Well, you must be visiting this hotel for the first time :)” one guy smiled.

Another one continued “Yes, We are aware of that, how they sell the bottled water. As you said, it’s their trick. But what you think about our cockroach trick? 😉 Justice is served, right bro?” one of the guy winked at me.

“So you brought the cockroach purposefully!” I wowed. 

“Yeah, hereafter these restaurant guys will always have a fear to play their dirty tricks on people. If they repeat, we will send another bunch of guys with a rat 😛 :)”

I shared my card with them and they assured a Facebook ‘friend request’.

Well, that’s the story of Mineral water with roasted Cockroach. Do you wish to carry some roasted cockroaches? 😉

– Words by Din

Bottom line: Why this story is mainly because of forced selling of mineral/ bottled water. Slowly the public is made to forget that there exists something called good tap water to consume. Pathogens? Almost all can be killed by boiling the tap water. Packaged drinking water is mostly a myth, they buzz around safety concerns. When your region’s ground water is polluted by chemicals, then we are left with no choice than to consume specially treated mineral water, either homemade using purifiers or commercially sold mineral waters. But why to consume bottled water when there is a good fresh water available in our region?

Know : Rain Water’s Purity Facts

rain water

The water in a raindrop is one of the cleanest sources of water available. Rainwater can absorb gases such as carbon dioxide, oxygen, nitrogen dioxide, and sulfur dioxide from the atmosphere. It can also capture soot and other microscopic particulates as it falls through the sky. Nevertheless, rainwater is almost 100% pure water before it reaches the ground.

Rainwater is soft water and leaves no limescale; washing clothes and hair in soft water requires less detergent and so reduces water pollution from these compounds. Plants LOVE rainwater. It doesn’t contain chlorine, which is carcinogenic.

Water is made “hard” by dissolving calcium or magnesium ions, neither of which is present in rain water (at least, not until it runs over calcium or magnesium containing compounds on the Earth’s surface). Pure water is considered the universal solvent; it can absorb or dissolve contaminants from almost anything it comes into contact with. That is why it is especially important to design and operate your system so that the rainwater picks up as few contaminants as possible before you consume it.

Although rainwater can be contaminated by absorbing airborne chemicals, most of the chemicals present in harvested rainwater is introduced during collection, treatment, and distribution. By properly designing and operating your rainwater harvesting system, you can minimize your exposure to a variety of chemical contaminants that include organic chemicals, such as volatile and synthetic organics, and inorganic chemicals, such as minerals and metals. 

Chemical composition of rain water :  Rainwater gets its compositions largely by dissolving particulate materials in the atmosphere (upper troposphere) when droplets of water nucleate on atmospheric particulates, and secondarily by dissolving gasses from the atmosphere.

Rainwater compositions vary geographically. In open ocean and coastal areas they have a salt content essentially like that of sea water (same ionic proportions but much more dilute) plus CO2 as bicarbonate anion (acidic pH).

Terrestrial rain compositions vary significantly from place to place because the regional geology can greatly affect the types of particulates that get added to the atmosphere. Likewise, sources of gaseous acids (SO3, NO2) and bases (NH3) vary as a function of biome factors and anthopogenic land use practices. Each of these gasses can be added in varying proportions from natural and non natural input sources (non-natural sources of SO3 and NO2 far outweigh natural ones). Particulate load to the atmosphere can also be greatly affected by human activities.

Finally, local climate (especially the amount of precipitation in one area compared to another) will affect the solute concentrations in terrestrial rainwaters. The result is highly variable compositions, so there isn’t one simple formula.

Reblog : What are the major Environmental problems affecting the African continent today?

What environmental problems are affecting the development of Africa today? Africa suffers from many environmental problems including deforestation, degradation and fragmentation, desertification, the loss of soil fertility, a dramatic decline and loss of biodiversity, air pollution, and water pollution. These problems hinder Africa from making progress with regard to economic development. Due to the fact that these issues are not fully understood, many Africans have been delayed in solving the problems.
