Hello, I am respectfully requesting help responding to the below discussion. I need to respond by applying the following:

Participate individually with meaningful and original comments in the dialogue of the posted discussion questions.

Ensure your posted content is written in your own words. Repetitive (redundant) answers, copied articles or portions of articles from Web sites, books, magazines and so on will not count towards participation

Cite properly and consistently and include all sources used for your responses

I choose pollution. Pollution comes in many forms whether its air pollution, water pollution, and land/soil pollution. Air pollution is caused by gases and toxins that come from factories. Water pollution is caused by oil spills or trash that people throw into the water, and soil pollution is caused by industrial waste that affects soil from getting its essential nutrients. All kinds of pollution can be harmful to plants, animals, and humans. Air pollution is the main pollutant in everyday life. Things such as cars, planes, power plants, and other human activities produce air pollution. "Pollution disturbs our ecosystem and the balance in the environment. "Water pollution not only harms the aquatic beings but it also contaminates the entire food chain by severely affecting humans dependent on these. Water-borne diseases like cholera, diarrhoea have also increased in all places." A solution for the pollution would be having a big fine for people that pollute, fix the cars, planes, and power plants to where they don't give off carbon dioxide, and find a way to prevent oil spills into the ocean. Some other solutions for each would be:

Air Pollution:

"Seek advice from environmental professionals when locating exhaust outlet"

"Use smokeless fuel, such as gas and electricity"

"No outdoor cooking, e.g. hotpot & BBQ"

Water Pollution:

"Remove the accumulated bottom sludge regularly"

"Engage registered grease trap waste collector for regular cleaning and overhauling of grease trap"

"Keep an updated drainage plan in management office"

"Check the drainage plan before carrying out of drainage works to ensure correct drainage route

Why is it usually not possible to restore a community to itspre-altered state?

  1. It is not always possible to determine the kinds of speciesthat populated a community.
  2. Invasive species compromise restoration.
  3. Climate change complicates restoration.
  4. Evolutionary trajectories cannot be predicted.

How is ecological restoration different from restorationecology?

  1. It considers cultural and societal concerns.
  2. It does not rely on ecological principles.
  3. It cannot be predicted.
  4. It does not involve manipulation of the environment.
  5. All answers are correct.

4.

What is the goal of assisted migration?

  1. to help species respond to climate change
  2. to help species learn new seasonal migration routes
  3. to help migrating species avoid human-made structures
  4. to help native species tolerate restoration efforts

  2. In ecosystems where fire is a natural periodic event, fire cankill many non-native plant species while leaving native speciesless influenced.
  3. Fire can suppress the growth of competitive dominant plants,such as shrubs and trees, increasing the diversity of certainecosystems.
