Describe how human activities have depleted ozone in the stratosphere. List
(a) three potential human health impacts
(b) three non-human impacts of stratospheric ozone depletion. Describe the relationships between higher UV levels and three types of skin cancer

a- Alteration or genetic mutations, high degree burns, severe dehydration

b-Drought of rivers, Extinction of species, Decrease of partial pressures of oxygen in the atmosphere.

Ultraviolet radiation genres severe genetic mutations that usually manifest in most humans as skin cancer, the three most common epithelial malignancies are: squamous cell carcinoma, basal cell carcinoma, melanoma

Explanation:

This happens because ultraviolet radiation acts as promoters or initiators of genetic mutations in genes that control cell proliferation, inhibitors of cell mitosis, and promote the activation of oncogenes, thus generating an imbalance in cell proliferation and acquiring malignant phenotypes in these cells.

Of the three malignant neoplasms named, the one that presents the highest risk of mortality is Melanoma, since it spreads (metastase) via the lymphatic and blood lines, and can reach possible brain areas.

just say i love u like a lot and your cute and hansome say that
