Time To Repay The Nature


Breathing is an activity of all the creatures on this planet & it’s a greatest blessing that we got from this earth to our daily survivals. But we have pulled in to a situation of purchasing the oxygen from the shop to breath. This incident has caused in china & Hong Kong recently according to the Reuters: “Millions of people in china and Hong Kong are breathing dirty air with terrible health consequences”.

Air pollution often has long-term health impacts that build-up slowly over time. It may also cause non-specific problems, such as weakened immunity. It is often easy to overlook the health impacts of air pollution. With a booming economy and ever-increasing demand for energy, China has built new coal-fired power plants at an astonishing rate. Today, coal provides over 60% of China’s electricity and the lion’s share of its air pollutants, from soot to sculpture dioxide. While cars and trucks also contribute to air pollution in cities, it will be impossible to improve air quality in China without moving away from coal.

Coal burning is the biggest contributor for air pollution in Beijing and surrounded area. China simply cannot afford to allow air pollution to continue taking such a heavy toll the country’s rapid growth in coal consumption has been brought on by extensive industrial expansion, which in turn, has increased pressure on the environment and public health conditions. In order to turn around the deteriorating air conditions, China must fundamentally change its development model, starting with a significant reduction in coal consumption.

At the same time earth oxygen level can influence global temperature and humidity as its concentration changes. Reducing oxygen levels thins the atmosphere, allowing more sunlight to reach Earth’s surface. More sunlight lets more moisture evaporate from the planet’s surface, which increases humidity. Because water vapour is a greenhouse gas, more heat gets trapped near Earth’s surface, and temperatures rise. The increased humidity and temperature also leads to increases in precipitation. By contrast, when oxygen concentrations are higher, the atmosphere gets thicker and scatters more sunlight. As a result, there is less water vapour to trap heat. “Oxygen levels are dropping today but at a very slow rate, approximately ten of parts per million per year. “This rate is much too slow to affect climate in the modern world.” Give the planet another million years, though, and future climate scientists will need to add oxygen to their models to get the full picture.
