Answer:
The correct answer out of the four given options is
option a. light elements with atomic numbers less than 5
Explanation:
Big Bang nucleosynthesis, abbreviated as BBN, also known as primordial nucleosynthesis took place after the Big Bang for about 10 s to 20 minutes and resulted in the yield of isotopes of helium-4 (
), helium-3 (
) which accounts for most of the world's helium, other isotopes of hydrogen in small amounts like deuterium (D or
) and lithium isotope, lithium-7(
) in small amount.
Apart from these stable nuclei, it also yielded two radio-active isotopes: tritium(
) and beryllium-7(
) which due to their unstability later decayed into () and ().
All of these isotopes are of light elements with atomic number less than 5.
Answer: Plastic Pollution
In 1950, the world produced more than 2 million tons of plastic per year. By 2015, this annual production swelled to 419 million tons and exacerbating plastic waste in the environment.
A report by science journal, Nature, determined that currently, roughly 11 million tons of plastic make its way into the oceans every year, harming wildlife habitats and the animals that live in them. The research found that if no action is taken, the plastic crisis will grow to 29 million metric tons per year by 2040. If we include microplastics into this, the cumulative amount of plastic in the ocean could reach 600 million tons by 2040.
Shockingly, National Geographic found that 91% of all plastic that has ever been made is not recycled, representing not only one of the biggest environmental problems of our lifetime, but another massive market failure. Considering that plastic takes 400 years to decompose, it will be many generations until it ceases to exist. There’s no telling what the irreversible effects of plastic pollution will have on the environment in the long run.
