Environmental science is the field of science that studies the interactions of the physical, chemical and the biological components of the environment, and also the relationships and effects of these components with the organisms in the environment.
In our recent environmental issue there is a dramatic outbreak of coronavirus, the impact of With global economic activity ramping down as a result of the coronavirus pandemic, it is hardly surprising that emissions of a variety of gases related to energy and transport would be reduced.
Scientists say that by May, when CO2 emissions are at their peak thanks to the decomposition of leaves, the levels recorded might be the lowest since the financial crisis over a decade ago.
However, while urban air pollution has declined in developed countries, the understanding of the widespread damage it causes to health has increase, and toxic air has risen to extreme levels in developing countries, such as India.
There is a significant impact ..
Traffic levels were estimated down 35% compared with a year ago. Emissions of carbon monoxide, mainly due to cars and trucks have fallen.
Countries that have been stringent lockdown to stop the spread of the coronavirus have experienced an un intended benefit. The outbreak has, at least in part, contributed to a noticeable drop in pollution and greenhouse gas emissions in some countries.
Although grim, it’s something scientists said could offer tough lessons for how to prepare and ideally avoid-the most destructive impacts of climate change.
Satellite observations have shown that the temporary measures have also driven significant decrease in harmful emissions.
Carbon dioxide is tied to industrial activity, electricity production and transportation. So anything that affects those sectors will impact greenhouse gases, as well.
It will depend on how long the pandemic lasts, and how widespread the slowdown is in the economy particularly in the US. But most likely we can see something in the global emissions this year.
But experts warned that observed reduction are temporary and that as cities, countries and economics bounce back, so, too, will emissions-unless major infrastructure or social changes are adopted.
In future, governments should engage environmental scientists and public health experts who can provide insights into the behaviour of this virus in the environment.
If we can think about how to prepare for climate change like a pandemic, maybe there will be a positive outcome to all of this.
We can help prevent crisis in the future if we are prepared.
As we move to restart these economies, we need to use this moment to think about what we value. We don’t want to go back to the status quo, but we want to tackle these big structural problems and restructure our economy and reduce emissions and pollutions.
It will depend on how long the pandemic lasts, and how widespread the slowdown is in the economy. But most likely we can see something in the global emissions.
