Explanation:

Adding chemical compounds like nitrogen and phosphates indirectly causes global warming as it poisons marine life which kills them. However note that its indirectly causing global warming, not directly.

Humans creating acid rain will cause some wildlife to die but the effect is not direct as well. It requires a process to result in global warming which takes time.

Humans adding CO2 to the atmosphere is a direct cause of global warming as CO2 is a greenhouse gas that traps heat radiated from the sun, causing global temperatures to rise.

Chemicals creating a thicker ozone layer reduces global warming as ozone reflects radiation from the sun. Hence the option is scientifically wrong in this question.

the nitrogen cycle provides nitrogen to the ecosystem from the atmosphere, ground and oceans. nitrogen is an important component of complex molecules such as amino acids and nucleotides, which lead to the creation of proteins and dna, the building blocks of all life. plants absorb nitrogen in the form of ammonium, nitrate ion and, on rare occasions, as amino acids. animals receive nitrogen necessary for biological processes from feeding on living or dead organic matter.

some scientists like gregory adcock agree with thorne's theory of regional continuity.

others, like chris stringer and ian tattersall, believe thorne's results may be contaminated or misinterpreted.
