Document Summary
The largely unacknowledgeable impact of climate change on mental health. Human health: environmental health is fundamental to human health, humans can become ill, or die from: Ingesting food, water or dust that is polluted. In canada, most waste is buried in carefully-selected, well-managed sanitary landfill disposal sites: disadvantages. Climate change: greenhouse gases: greenhouse gases in the atmosphere (co2, nitrous oxides, methane, water vapour) insulate the earth, gree(cid:374)house effe(cid:272)t keeps the earth"s te(cid:373)perature at 15 c (vs -18 c, greenhouse effect is natural. Climate change: human-produced greenhouse gases: humans burn large quantities of fossil fuels, this emits co2, greenhouse effect is heightened, less ir escapes atmosphere, te(cid:373)perature of earth"s surfa(cid:272)e a(cid:374)d lo(cid:449)er at(cid:373)osphere rises, global warming alters weather climate change. Climate change: impacts: fewer cold days/nights; more frequent and hotter days/nights, heavier, more extreme precipitation (with severe storms and flooding, more heatwaves, more droughts. Increased incidence of storm surges; higher sea levels.
