We need it to breath.
Acid rain is hurtful as well as mercury (and mercury isn't really in the air, but more in the fishes), ozone is hurtful if it is too low in the atmosphere (so air pollution).

Living organisms undergo vital processes such as respiration, excretion, digestion, and reproduction to survive.
Respiration in Living Beings
- Respiration is the breakdown of sugar molecules in the presence or absence of oxygen to yield ATP.
- Repatriation is a series of reactions in aerobically respiring organisms, such as glycolysis, Kreb's cycle, and oxidative phosphorylation with electron transport chain.
- In respiration, most living organisms use oxygen to make energy or ATP from glucose.
Thus, the living organisms who respire aerobically use oxygen to break down glucose and release ATP molecules.

Meiosis is a cell division which results in the reduction of chromosome number by half - from diploid to haploid - in daughter cells. It consists of meiosis I and meiosis II. Meiosis I produces two haploid cells. Meiosis II is analogous to mitosis, so each of these two haploid cells will in meiosis II produce two haploid cells. In total, meiosis results in four haploid cells.
Final answer:
Meiosis I produces two cells, both of which are haploid. This means each cell has half the number of chromosomes as the parent cell. This is a crucial step in sexual reproduction, promoting genetic diversity.
Explanation:
Meiosis I produces two cells, each of which is haploid.
During the process of meiosis, a cell initially has two copies of each chromosome, one from the mother and one from the father (46 in humans). This is called a diploid state. However, after meiosis I, it splits into two cells each containing half the number of chromosomes (23 in humans). These cells are said to be haploid because they only possess one copy of each chromosome. The division which occurs during meiosis I is a fundamental part of the sexual reproduction process, as it leads to genetic diversity in offspring.
