The world today is focused on Global
Warming, and is mainly concentrating on the reduction of carbon emissions,
which is said to deplete the ozone layer, leading to many complications. Global
warming is a phenomenon which is caused by increase in the temperature of
earth. Due to increase in the temperature of earth, the ice present at the poles
melts and it also leads to many environmental changes. You will be astonished
to know that the temperature of our earth has increased by a couple of Celsius
degrees within this century and if the present trend continues scientists estimate that
by next ten years all the ice present at poles will melt.
We are already confronting serious
problems with increase in temperature of earth due to carbon dioxide. Now
scientists in Germany have come out with a warning of a new danger.
Hydrogen, they say, is more dangerous than emission of Carbon. Although it is
inert in its own form, it is reactive when combined with other agents to form
compounds such as ammonia, use of hydrogen based fertilizers, and so on. These
compounds also create several forms of pollution such as smog, greenhouse warming, haze, acid rain etc. In other
words, the effect of the reactive compounds of Nitrogen pollution is nearly the same as
that of Carbon Dioxide. Thus now we have to fight with two different gases
which give rise to same effect which can be a potent threat to our survival.
There are present measures through which we
can control the amount of nitrogen oxides being generated. Ways of reducing use
of nitrogen ranging from reusing nitrogen from manure and sewage, reduction in
nitrogen emissions, and encouraging its uptake by plants are being studied by researchers. It is beneficial to control this damage before it is too late, or else we may have to face same
problems we are facing today in an aggravated state.
