Environmental Health Why do we care? What are the long term impacts of waste and overuse? What are the causes of pollution? Does the earth have unlimited resources? What about Population and the earth’s resource https://en.wikipedia.org/wiki/World_population How much do certain societies use…re-use things- disposable coffee cups, throwing away plastic bottles, throwing away glass jars, wasteful

Population growth Graph of population growth? Population and increase in CO2 levels in air Co2 levels in air increase global warming Trees use CO2 People use more resources…need more food stress the ecosystem to provide resources US is greed with resources… re-use things like bags and glass containers, plastic containers Producing these things needs power

Climate change Is the earth getting hotter of colder Past ice ages Past hot times https://en.wikipedia.org/wiki/Geologic_temperature_record

Climate change Paleocene-Eocene Thermal Maximum During the PETM, the global mean temperature seems to have risen by as much as 5-8 °C (9-14 °F) to an average temperature as high as 23 °C (73 °F), in contrast to the global average temperature of today at just under 15 °C (60 °F). Geologists and paleontologists think that during much of the Paleocene and early Eocene, the poles were free of ice caps, and palm trees and crocodiles lived above the Arctic Circle, while much of the continental United States had a sub-tropical environment.[5]

Climate change Ice age However, other evidence suggests that the period of 2,000 to 3,000 million years ago was very generally colder and more glaciated than the last 500 million years.[citation needed] This is thought to be the result of solar radiation approximately 20% lower than today. Solar luminositywas 30% dimmer when the Earth formed 4.5 billion years ago,[13] and it is expected to increase in luminosity approximately 10% per billion years in the future.[14]
