Cost of Flying



I have always envied the birds for their flight. I mean, humans also have the option of taking a flight now but then it's still not so easy.

The cost for humans for the flight is alot but also the environment pays everytime we use this option. Travelling by aeroplane may only account for 2% of total global greenhouse gas emissions, but those 39.4 million annual flights pump out toxic nitrogen oxide, cancer-causing exhaust particulates and carbon dioxide. But, the total global warming impact of each flight is thought to be around twice as high as the CO2 emissions alone. At flying altitudes in the upper troposphere and lower stratosphere, these outputs produce a range of climatic effects, multiplying the plane's environmental impact. For example, nitrous oxide causes the formation of ozone — a greenhouse gas that warms the local climate — but at the same time undergoes reactions which destroy methane, thereby removing another greenhouse gas from the atmosphere.
Even though less than 20% of human population has flown, with the increase in globalization and resultant traveling, the number of flights are expected to double by 2037.

A number of commercial airlines are already experimenting with using biofuels to fly and the International Air Transport Association predict that a million flights will be powered by a mixture of biofuels and conventional fuels by 2020. These aren't an ideal solution, since biofuels can be environmentally problematic in themselves, and anyhow it would take a huge chunk of the world's arable land to grow enough crops to fuel all the world's planes.

Till the time, we are able to create carbon neutral travel a possibility, we will have to pay a heavy cost of being globe trotters.

Cat Stretch


Nature is a place having infinite wisdom. It's the source of most of our imaginations and creativity. It's also the place for most of our learning.

The learnings offered by nature can be as massive as the gravitational force that keeps us alive on earth, or as fundamental as the interdependence among all the biotic and abiotic components. Whenever we are lost, we turn to nature, our biggest inspiration.

Without nature, we have a very limited understanding of even our basic physiology. In the era of technology and fast food, we are losing our fitness, flexibility of our body. But our muscles are not meant to rest all the time. They need to work, and they need to stretch.

The way cats stretch is very effective in stretching their spine and many of their important muscles. When they get up after long inactivity, they stretch to get their muscles ready and flexible for action again.

Cat stretch is one of the most commonly used yoga move used all over the world....yet another gift of nature.

Disposable fashion


Have you heard of really cheap clothes, where the quality is such that they may survive only 3-4 wash only. They are styled in the latest fashion as the production for these is easy and quick. This disposable culture is invention of our generation only. We have invented everything to be single use.

But do we think what will be the impact of this mass production on the environment? Nature can't dispose these items the way human can discard. Our speed of discarding can not be matched by nature's speed of decomposition.

All these fashion new trends soon become part of the garbage problem. These kinds of fashion is antithetical to the philosophy of "reuse-reduce-recycle". At the end, the choice is ours whether we want to be driven by short term pleasure or focus on sustainable development.

God's Judgement


It's said that God made humans to be an image of his own. After looking at all this destruction, do you think God will be regretting the decision to make humans?

Looking at the massive Extinction being caused by humans, what exactly will be the judgement received for us at the end of the road?

Or maybe God believes that everything that lives should die and that's why he created humans to be the destructors of the earth. But do we even realize the role we are playing?

Climate Crisis Part 7

Human mind has infinite capacity for imagination in most cases. One place where our imagination lacks is the idea of life after us. We can't imagine a world where we don't exist, we always want to go on living, may it be through our offspring or our legacy.

I think one of the challenge we face against actionizing to stop climate change is this inability of ours. We tend to think that there will always be a world where there will be humans. What we don't understand is that we need the earth, the climate to sustain us and not the other way around. Even if the temperature continues to rise and earth ceases to be a suitable living planet for humans, earth will exist, even some other living beings will exist. But humans, we will also be extinct just like many species are going extinct now.

Climate Crisis Part 6


The biggest issue with climate change is the uncertainty associated with it. Our lack of knowledge adds on to the challenge. Whatever actions we take, we will make mistakes. It's important to learn from the mistakes and evolve. We cannot be disappointed by failure.

There is a concept called Adaptive management in environmental studies. In adaptive management, hypothesis driven experiments are designed. The results of these experiments are closely monitored. Any deviation in results from what was expected at the time of planning is considered as new learning and incorporated into the next level of experiments. Uncertainty is considered to be an opportunity to learn complex ecosystem functionality.

Climate change may be the best place to implement adaptive management due to the complex nature of climate change and its uncertainties.

Climate Crisis Part 5


Climate crisis is not something that can be handled at a local or national level. It needs international collaboration from every level of government, local, state, federal, international, non governmental agencies, indigenous communities and general public. A mass awareness is needed, and mass change of lifestyle all over the world. Governments need to work closely with Environmental NGOs, indigenous communities and local people to implement strategies to deal with the crisis.

In terms of awareness, it's very hopeful to see the climate strike that happened in September this year. It just tells us that a lot more people now want actions which can push the governments to take some actions sooner rather than later. Also it tells us that general public are not powerless. They can create a mass movement if they really want.
