Emerging Issues in Global Environment

Our Environment is pretty fragile. We have big economic forum meeting, we have the G20, we have the NATO but each of the aforementioned were formed to solve the ulterior motive.

We all know Newton and his laws of motion but Newton’s laws remaining the same only the heading can be changed Newton’s law to reality. We are not not naive to see where I am heading with this. Our actions are creating what I will be mentioning below.

United Nations Environment Programme Year Book, 2014 brought out in open emerging issues in global environment.

1.) Excess nitrogen in the environment 
The global nitrogen cycle has been profoundly altered by human activity. Excess nitrogen affects air, water and soil quality, putting pressure on ecosystems and biodiversity and leading to human health risks.

2.)Re-emergence of infectious diseases 
Environmental change plays a major role in both the emergence and re-emergence of infectious diseases.

3.)Marine fish and shellfish farming
Pressures on freshwater and terrestrial ecosystems are increasing, including those related to climate change. Marine aquaculture provides food from the oceans.

4.)Illegal wildlife trade
The illegal wildlife trade is more than a potential death sentence for some of the planet’s iconic animals.

5.)Methane hydrates 
A vast reservoir of methane is frozen in methane hydrates in ocean sediments along continental margins and in permafrost regions. Natural gas obtained from this source could potentially help meet future energy needs. However, complex challenges need to be met.

6.)Air quality 
Air pollution is the world’s single largest environmental health risk. Despite its enormous human, environmental and economic costs, it is getting worse, with particular concerns associated with urban areas.

7.)Plastic debris in the ocean
Plastic debris is found in marine ecosystems worldwide, including in the polar regions. Fragments of plastic – including very small ones called microplastics – can accumulate and distribute chemical contaminants.

8.)Soil carbon benefits
Over twice the amount of carbon in the atmosphere is stored in the top metre of the world’s soils. Because soil carbon has a central role in many ecosystem services, its good management can help meet challenges including food and energy security, water availability and quality, climate change adaptation and mitigation, and biodiversity conservation.

9.)Rapid changes in the Arctic
 The Arctic is more closely connected to the rest of the world than ever before. Accompanying losses of sea ice and unique biodiversity, and other impacts of global warming, new opportunities exist for economic development. However, urgent responses are needed to slow the pace of change in this fragile region and increase its resilience.

Energy Solutions:It is there but we don’t know yet

Sometime back I was reading about Greatest Minds and I read about Srinivas Ramanujam. He was and is perhaps the greatest mathematical mind that the world has ever seen. Without any formal education he worked out brilliant formulas. He always used to say that we don’t invent things because they are already there, the thing is we don’t know about all these things yet.
Now, imagine that you time travel to 11th century and just think what Srinivas Ramanujan said. Equation of aerodynamics, Equation of Thermodynamics, Equation of Electro-magnetism, Gas Laws, Gravitation. Everything answer, every equation was already there until it was found by the great minds. Likewise, we are always working towards achieving a sustainable energy environment and we are attempting new efficient ways for achieving clean-tech energy. 
To achieve our energy goals, resources are there but we just don’t know much and we need to know more.
