Strong Answer: Farmers can use crop rotations to prevent the buildup of large populations of pests that feed on one crop, ie boll weevils for cotton, while also introducing predators and parasites that prey upon pests to reduce pest populations.]]> 2020-04-29 05:59:04 UTC https://padlet.com/cchambers16/56zp6w0var0v2vs/wish/538182209 2008592 https://padlet.com/cchambers16/56zp6w0var0v2vs/wish/538182211 Question: Describe one ecological and one economic impact of resource extraction through mining.
Weak response: Mining creates jobs but can cause acidic drainage.
Strong response: One ecological impact of mining is acidic drainage. Acidic drainage occurs when iron sulfide in the waste from the mine reacts with water and the air to form iron and sulfuric acid. This acidic waste leaves the mining area through waterways and can negatively impact the environment by killing species. For example, many species of fish can only live within a certain pH range. By increasing the water's pH with acidic drainage, it is making the environment too hostile for the fish to survive in. An economic impact of mining is that the engineering, construction and operation of mines require labour, therefore creating jobs and boosting the economy.]]> 2020-04-29 05:59:04 UTC https://padlet.com/cchambers16/56zp6w0var0v2vs/wish/538182211 https://padlet.com/cchambers16/56zp6w0var0v2vs/wish/538182223 Weak response: Ethanol does not release net CO2 but corn needs a lot of fertilizer to grow.

Strong Answer: One of the benefits of using biomass as fuel is the availability and fast regeneration of sources of biofuel. However, many forms of biofuels (wood, palm oil, ethanol) require large areas for farming which can disrupt natural habitats and cause long term damage to the ecosystem.]]> 2020-04-29 05:59:05 UTC https://padlet.com/cchambers16/56zp6w0var0v2vs/wish/538182223 https://padlet.com/cchambers16/56zp6w0var0v2vs/wish/538182398 Weak response: Impervious surfaces hurt the water cycle, but people can also use mass transit.
Strong response: A positive effect of urbanization is the increased usage of public transportations which decreases the air pollution emitted from car's burning of gasoline. A negative effect of urbanization is the increase implementations of impervious surfaces such as driveways. Impervious surfaces prevents water from being absorbed by the soil in the ground which decreases the underground water storage. It also leads to runoff entering the ocean, lakes, and rivers and causes water pollution in those bodies of water such as eutrophication. ]]> 2020-04-29 05:59:15 UTC https://padlet.com/cchambers16/56zp6w0var0v2vs/wish/538182398 https://padlet.com/cchambers16/56zp6w0var0v2vs/wish/538182421 Weak response: IPM is not using pesticides.
Strong response: IPM is a strategy utilized by farmers which is meant to reduce pests to a level where they do not disturb crop outputs, without the excessive usage of pesticides. One example of IPM is the introduction of a predator species such as ladybugs, which will consume the pests, aphids. These ladybugs will effectively eradicate the aphids, while not posing a threat to the plants, or disrupt the economic output of the farm. ]]> 2020-04-29 05:59:17 UTC https://padlet.com/cchambers16/56zp6w0var0v2vs/wish/538182421 https://padlet.com/cchambers16/56zp6w0var0v2vs/wish/538182444 Weak: El Niño leads to a warm Pacific Ocean and La Niña leads to a warm Pacific Ocean.
Strong: El Niño is a weather phenomenon that is caused by the weakening or change in direction of trade winds, which ultimately leads to warmer temperatures in the water, affecting some species of marine animals and sea birds resulting in migration and wetter weather. La Niña, on the other hand, is essentially the opposite of El Niño, where trade winds and ocean currents bring cooler water up to the surface through upwelling, leading to droughts and dry seasons.]]> 2020-04-29 05:59:18 UTC https://padlet.com/cchambers16/56zp6w0var0v2vs/wish/538182444 https://padlet.com/cchambers16/56zp6w0var0v2vs/wish/538182542 Weak response: Prescribed burns and only purchasing sustainable wood products will mitigate the
human impacts on forests.

Strong response: Fish farms hold large amounts of fish in high concentrations which can unintentionally transfer diseases and parasites between different fish populations, increasing the chance of contracting an illness. 

As the global population continues to increase, aquaculture is able to keep up the demand for fish as well as efficiently provide protein.  ]]> 2020-04-29 05:59:23 UTC https://padlet.com/cchambers16/56zp6w0var0v2vs/wish/538182542 https://padlet.com/cchambers16/56zp6w0var0v2vs/wish/538182571 Strong Answer: Enforcing stricter regulations (putting a quota) on the number of trees cut or burned per day as well as restore forest landscapes (by planting more trees or fire prevention) that were previously lost in order to mitigate the human impacts. ]]> 2020-04-29 05:59:24 UTC https://padlet.com/cchambers16/56zp6w0var0v2vs/wish/538182571 https://padlet.com/cchambers16/56zp6w0var0v2vs/wish/538182684 Question: Describe one negative and one positive effect of the use of hydroelectricity in power
generation on the environment.
Weak response: Hydroelectric dams hurt fish but do not make any waste. 
Strong answer: As hydroelectric dams are built in the natural environments for many fish (rivers, lakes, ponds, etc) fish could easily be hurt or even killed by swimming into a dam. Furthermore, the presence of a dam could disrupt mating seasons by preventing populations from meeting if the dam blocks their pathway. On the other hand, hydroelectric dams do not directly release any fossil fuels with each additional amount of energy created, so the presence of the dam does not pollute the surrounding area with pollutants such as CO2, NO2, CH4, etc. that could potentially harm the environment in the body of water or air. ]]> 2020-04-29 05:59:31 UTC https://padlet.com/cchambers16/56zp6w0var0v2vs/wish/538182684 2007399 https://padlet.com/cchambers16/56zp6w0var0v2vs/wish/538182767 2020-04-29 05:59:36 UTC https://padlet.com/cchambers16/56zp6w0var0v2vs/wish/538182767 https://padlet.com/cchambers16/56zp6w0var0v2vs/wish/538182813 Strong Response: Nitrogen oxides are produced in virtually all combustion processes in the atmosphere on Earth. Hotter burning condition and the presence of oxygen allow more nitrogen oxide to be generated per unit of fuel burned. In order to reduce Nitrogen Oxides, burn temperatures must be reduced, and the amount of oxygen must be controlled. Additional examples to reduce nitrogen oxide in the atmosphere include installing catalytic converters in your vehicle, and avoiding the use of nitrogen fertilisers. 
The production of Co2 can be reduced through a decrease in the amount of coal that is burned. Another way to reduce the production of CO2 is through using renewable energy sources, such as wind and solar, instead of coal for energy. ]]> 2020-04-29 05:59:38 UTC https://padlet.com/cchambers16/56zp6w0var0v2vs/wish/538182813 https://padlet.com/cchambers16/56zp6w0var0v2vs/wish/538182889 Question: Describe a cause of and a problem related to overfishing.
Weak response: People accidently kill bycatch which destroys the ocean food web. 
Strong Response: 
 Trawler fishing is a fishing method in which large nets collect large amounts of fish. Eco Sonar allows for exact location of where fish are in deep waters, more accuratley finding the pods of fish. This relates to overfishing because as tech of fishing increases there will be an increase in yeild of fish leaving less in the ocean. Inn addition it increases the likleyhood of bycatch happening, where not target fish get collected and sometimes die in the nets.

Strong Response: Wind energy is a clean fuel source which means it doesn't release any C02 or toxins that burning fossil fuels release. Wind is also a renewable source, meaning you can't run out of wind. One negative effect is the cost of the turbines and the cost of the battery that is used to store the energy. Also, people don't like to live nearby because of the noise pollution it creates. ]]> 2020-04-29 05:59:44 UTC https://padlet.com/cchambers16/56zp6w0var0v2vs/wish/538182911 https://padlet.com/cchambers16/56zp6w0var0v2vs/wish/538183079 Crop rotation is a form of IPM (Integrated Pest Management) that reduces the use of pesticides while also decreasing the amount of pests because of the rotation of crops. Rotating the crops can prevent large populations of pests to buildup over time. Another form of IPM would be No-till plowing. This method helps to enrich the soil and reduce help to maintain moisture. ]]> 2020-04-29 05:59:53 UTC https://padlet.com/cchambers16/56zp6w0var0v2vs/wish/538183079 https://padlet.com/cchambers16/56zp6w0var0v2vs/wish/538184508 Human populations experience growth when reproduction rate is high, birth rate is high, and death rate is comparatively lower. This is usually an indicator that the population is in the early stages of the demographic transition model, specifically the first and second phases, where education is lacking and knowledge regarding family planning and reproductive contraception is uncommon. Human populations experience decline when the inverse is true, namely when birth rate is relatively lower than death rate. This is usually an indicator that the population has reached its post-industrial stage, where the standard of living and sanitation are high, women are educated, knowledge regarding sexual and reproductive health is widespread, and contraceptions are commonly used. ]]> 2020-04-29 06:01:16 UTC https://padlet.com/cchambers16/56zp6w0var0v2vs/wish/538184508 https://padlet.com/cchambers16/56zp6w0var0v2vs/wish/538184550 Human populations grow and decline as a result of different factors such as economic development, education, and birth/death rate. The demographic transition model indicates how the relationship between birth and death rates directly affect population growth. The birth/death rates in stage one are both high, resulting in a low total population. As birth and death rates decrease, both at different rates, total population begins to increase.]]> 2020-04-29 06:01:19 UTC https://padlet.com/cchambers16/56zp6w0var0v2vs/wish/538184550 https://padlet.com/cchambers16/56zp6w0var0v2vs/wish/538190339 Weak response: Drip irrigation causes less salinization and erosion.

Strong Answer: Drip irrigcation can be beneficial because it acts as a direct link between water and crops. This direct link increases the ability to conserve water as well as nutrients. Furthermore, the direct link reaches the roots, so water is used more efficiently and less is lost to evaporation.

During the installation of micro irrigation systems, rarely does the landscape necessitate excavation and destruction of the land bed’s integrity.]]> 2020-04-29 06:06:19 UTC https://padlet.com/cchambers16/56zp6w0var0v2vs/wish/538190339 cchambers16 https://padlet.com/cchambers16/56zp6w0var0v2vs/wish/566635776 2020-05-12 06:17:35 UTC https://padlet.com/cchambers16/56zp6w0var0v2vs/wish/566635776
