Lake Huron is one of the Great Lakes and a major part of our fresh water system, which contains many wildlife and species. The lake however, is in a real danger, adversely effecting habitats, fish, wildlife, and human lives. Lake Huron has become a dumping ground for many companies, dumping waste that contains many pollutants. Bacteria levels have increased in the lake which can cause serious illness. These pollutants have reduced water quality, contaminated soils, and damaged the Lake’s ecosystems.
What is the percent of CO2 in the atmosphere that humans are emitting per year relative to preanthropogenic levels? (Hint: divide the rate of increase (2 ppm/year) by the amount of CO2 in 1850. and multiply by 100). 5. There were 600 gigatons (106 tons) of carbon in the atmosphere in 1850. How many gigatons accumulated in the atmosphere each year due to human activity?
As a result of this, plants and animals are forced to adapt to significant changes that threaten their way of life. As explained by Suzuki in the article, every year at least twenty thousand species disappear forever and the rate of extinction is speeding up largely due to human activity. Many living things are now paying the price for all the man made pollution that has been created as a result of global warming. Furthermore we as a community do nothing to stop global warming and feel no sense of responsibility or duty to care for the overall well being of our world. Big businesses are releasing harmful chemicals into the atmosphere and oceans.
Environmental health Unit 38 P1 Explain how human activity can damages the environment For years now we have been warned about human activity destroying our planet and environment. Some of the things that humans are affecting are Climate Change, Depletion of Ozone Layer, Pollution, Deforestation and Extinction of Species. Overcrowding, urbanisation and population growth Overcrowding can affect our planet more than some people think, Overcrowding means more people this means we use more natural resources this means the earth in the end isn’t going to have enough resources to support the growing population. Remember every person on the planet takes up space which could be used for farmland, and forests. People excrete wastes and litter that flow into water systems, and animal habitats, this is slowly polluting water and killing wildlife.
According to Everglades.org, they’ve “contributed to nearly 70 percent of extinctions in the United States” and are the “primary cause of species endangerment.” The water itself is a major cause of decline to the area, firstly because of poor water management leading to water levels being too low or too high at the wrong times has caused a decline in many species. Secondly, poor water quality has had devastating consequences. The pollution and an abundance of toxins and nutrients has helped to kill off many living things in the
Due to sea level rising coral reefs are getting destroyed, as they cannot survive in water above 25m. Also the increase of sea levels changes the nutrient flow, which will further damage the food chains. Furthermore coral bleaching is another side affect of global warming which affects the coral reef. Coral bleaching is permanent damage and is effected globally. It gets especially worse during an El Nino year.
Modernity may cease with global warming as half the biggest companies are oil companies, and oil is the essence of life. Deforestation and the effects of global warming on our forests and trees are far-reaching and quite evident. All our planets physical features are changing rapidly. And McKibben repeats himself on purpose to get his point across: the planet we knew is no more, we live on a new, more complex and harsher
Sunspots and Flares Our Sun, the 5-billion-year-old star that sustains life here on Earth, powers photosynthesis in green plants and is ultimately the source of all food and fossil fuel. The connection and interaction between the Sun and Earth drive the seasons, currents in the oceans, weather and climate. With a core reaching a fiery 16 million degrees Kelvin (nearly 29 million degrees Fahrenheit), the Sun's surface temperature is so hot that no solid or liquid can exist there. As early as the fifth century B.C., the Chinese reported having observed dark spots on the sun. In 1960, Galileo Galilei of Italy, Johannes Fabricius of Holland, Christopher Scheiner of Germany, and Thomas Harriott of Englandeach independently
Carbon dioxide is a heat trapping greenhouse gas. It gets “released through human activities such as deforestation and burning fossil fuels, as well as natural processes such as respiration and volcanic eruptions” (Global Climate Change: Key Indicators, 2014). An increase in carbon dioxide means more heat is trapped thereby raising the Earth’s temperature. Global surface temperature needs to also be monitored. Not just one area but globally!
Consequently for every barrel of oil, there are 5 barrels of water consumed within the process. The oil sands have also led to the complications of social problems within Alberta. Such as housing crisis’s, due to the large expansion of new foreign workers. Nonetheless due to the implications of constructing oil reserves, it has caused much wildlife to disperse. This is significant, because if one species of animals departs, it causes the food cycle to be rearranged endangering the lives of multiple living organisms.
