Describe how green plants affect the abiotic environment in ways that are advantageous to humans. Describe how green plants affect the abiotic environment in ways that are advantageous to humans. Plants increase water supplies that humans can use for drinking, irrigation, or industrial use. Plants build soils required for human agriculture and forestry. Plants release carbon dioxide that we breathe. Plants release oxygen that we breathe. Plants hold soils required for human agriculture and forestry. Plants remove salts from water so humans can use it for drinking, irrigation, or industrial use.

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
