On one condition, pls paste the pictures on your own.

About COVID 19: is a virus that has taken over 1 lakh people of the world.

This pandemic has taken over the world and the poor people are in need during this chaos. In India, such states like Maharashtra, Gujarat, Tamil Nadu have many cases. Slowly, the lockdown/quarantine extends. The most affected countries are America, Soudi Arabia, France, Italy, Spain etc. have many people affected.

PROS: we are able to spend some quality time with our family, not needing to wake up every morning, watch some entertainments, and write a note or diary about what is going on during this time.

CONS: not able to travel outside, not able to go on parks and makes us very bored sitting home alone.

Answer:

Smog and soot

These two are the most prevalent types of air pollution. Smog, or “ground-level ozone,” as it is more wonkily called, occurs when emissions from combusting fossil fuels react with sunlight. Soot, or “particulate matter,” is made up of tiny particles of chemicals, soil, smoke, dust, or allergens, in the form of gas or solids, that are carried in the air. The EPA’s “Plain English Guide to the Clean Air Act” states, “In many parts of the United States, pollution has reduced the distance and clarity of what we see by 70 percent.” The sources of smog and soot are similar. “Both come from cars and trucks, factories, power plants, incinerators, engines—anything that combusts fossil fuels such as coal, gas, or natural gas,” Walke says. The tiniest airborne particles in soot—whether they’re in the form of gas or solids—are especially dangerous because they can penetrate the lungs and bloodstream and worsen bronchitis, lead to heart attacks, and even hasten death.
