Suppose that record snows blanket your campus this winter. Your friend says this is proof that global warming isn't really occurring. What is the flaw in your friend's logic? a. The average temperature of the Earth is not actually increasing. b. Global warming refers to temperatures, but snow is a type of precipitation. c. While the average global temperature is increasing, local temperatures and precipitation (weather) will vary. d. Your friend is confusing global warming and global climate change.

Hi everyone. Let's look at our next problem. It says which of the following pollutants is considered very harmful as it can pollute the environment for an extended period of time So all of our answer choices are pollutants. But we're looking for the choice that's particularly harmful due to how long it complete the environment. Well when we look at our answer choices, we have choice. A human organic wastes choice be non biodegradable pollutants. Choice C wastes from feedlots and choice. D natural nutrients present in excess. Let's note that choice is a see and D the human organic wastes waste from feedlots and natural nutrients present in excess are natural products that can be broken down by D. Composers. So all these are pollutants that can cause problems. Natural nutrients presence in excess can do things that cause algae blooms and lakes that they can cause issues that result in deaths of other species. Human organic waste and waste from feedlots um often have can carry cause disease and carry pollutants themselves. So all of these are pollutants and cause problems but they're broken down by D. Composers and eliminated over time. This is as compared to choice, be non biodegradable pollutants. And this is going to be our answer here. Um Because these are things that cannot get naturally decomposed or at least are not broken down in any sort of reasonable length of time. Um These are things that are generally often synthetic and don't break down easily. So things like plastic glass and batteries. So these are pollutants they pollute the environment. Um And then they just last sit around for a long time. They also can do things like blocking drains and harming animals, as well as just the pollutant effect themselves. So the answer to which of the following pollutants is considered very harmful. As it can pollute the environment for an extended period of time is choice be non biodegradable pollutants in the next video.
