Are We Protecting our Natural Resources?

Are we protecting our natural resources? If we ask this question to ourself, our answer would be no. Yes, we know that our natural resources are getting depleted, but still we take it as granted. We dont show any sort of gratitude towards nature. When you study any research against natural resources, it is hard to digest that we lost many natural resources. The famous Indian water guru Anupam Mishra said on one of his interview that "we don’t use our own resources well.When the British first came to India (in the 1850s), Delhi had almost 800 water sources of its own. Now there are no more than 10, and even those are heavily degraded. Delhi’s groundwater is being depleted very fast."

"Without such water bodies, not only are we not collecting rainwater in our cities, we also suffer from flooding when the rains come. There is no resilience. Not a single modern city will escape this threat. Look at the 2005 Mumbai floods - this will only worsen in the future and there is no sign of anyone solving the problem wisely." We also lost many plants that acts as a life saving medicine due to deforestation of forest. I dont whether this condition is going to improve or going to get still worsen. As like you, me also waiting for something good to happen on protecting our natural resources. This what we can do? Isnt it?

Global Warming Affects Food Chain in Artic Ocean

Over the past decade, the annual bloom of phytoplankton in the Arctic Ocean has been arriving earlier each year - a change that could hurt the marine food chain and carbon cycling in the region, according to a new research.
Scientists from the Scripps Institution of Oceanography (UC San Diego), Mexico and Portugal have attributed the shift to warming temperatures and melting ice in the Arctic.
Using satellite data from 1997-2010 depicting ocean colour and phytoplankton production, they found that the spring blooms have been arriving up to 50 days earlier in some areas over this 10-year period.
The researchers said the earlier Arctic blooms have roughly occurred in areas where ice concentrations have dwindled, creating gaps where the bloom can briefly flourish.

During the one to two week spring bloom, which occurs in warm as well as cold regions, a major influx of new organic carbon enters the marine ecosystem through a massive peak in phytoplankton photosynthesis, which converts carbon dioxide into organic matter as part of the global carbon cycle.
Phytoplankton blooms stimulate production of zooplankton, microscopic marine animals, which become a food source for fish.
"The bloom provides a major source of food for zooplankton, fish and bottom-dwelling animals. The advancement of the bloom time may have consequences for the Arctic ecosystem."
Mati Kahru, lead author and a research oceanographer at Scripps, said that it was not clear if fish will adapt to match the change, and whether it would disrupt their critical life-cycle stages such as egg hatching and larvae development.
"The spring bloom provides a major source of food for zooplankton, fish and bottom-dwelling animals. The advancement of the bloom time may have consequences for the Arctic ecosystem," he said.
Such a match or mismatch in timing could explain much of the annual variability of fish stocks in the region.
"The trend towards earlier phytoplankton blooms can expand into other areas of the Arctic Ocean and impact the whole food chain," the researchers concluded.

India-US Force in Global Warming Reduction

India and US have set up a task force in order to reduce global warming and this decision was taken at a joint Indo-US workshop on HydroFluoroCarbons (HFCs) attended by environment minister Jairam Ramesh and US deputy assistant secretary of state for environment Daniel A Reifsnyder. In the meeting they have concluded to establish a team that comprises of Industry representatives, scientists, and government officials to suggest options for HFC phase-down. 

Speaking at the workshop,  Environment minister of India MR. Jairam Ramesh said, "India recognises that while HFCs, a substitute for CFCs and HCFCs, are a 'solution' from an ozone depletion perspective, they are a 'problem' from climate change perspective, since they have high global warming potential."They are going to form a four level approach to tackle this problem. What are those four level approaches? For more information on these news, keep seeing  this blog( save earth).

Trees

Trees, they play a major role in saving global warming because they inhale most of the carbon di oxide and other gases that have been released from the earth. It prevents the erosion and maintains the ecosystem. It produces oxygen in abundance and it shows a variety of growth forms. Compared to other plants, the trees are long lived and some of the trees have reached thousand years old. Trees are environmental friendly and try to increase the water level content in ground by preventing soil erosion.

They provide shelter to animals and birds and balance the ecological nature. They are used for edible products and the fruits and vegetables that we get from them provide a healthy food. They purify the air and they are the longest living organisms on earth. So stop deforestation and love your earth

Atmosphere

The atmosphere is generally about air and nitrogen, oxygen and argon together constitute the major gas of the atmosphere. The refractive index of the air is just closer and greater than 1. UV radiation are absorbed by the atmosphere and a dry air by its volume contains 78.09% of nitrogen, 20.95% of oxygen and 0.039% carbon di oxide. dust, pollen, spores, sea spray, volcanic ash and industrial pollutants are also present in the atmosphere. Exo, Thermo, Meso, Strato and Tropho sphere are the different layers of atmosphere and these are arranged from highest to lowest.
