What are some examples where humans had a positive impact on the environment with their activities and where there were some negative impacts?



Answers

Name three locales where humans have settled with unfortunate environmental consequences. What are those consequences? (pages $566-67$ )

Hello there students today we're going to talk about um describe about the niche um they got for nature of humans and also how science and technology um had an effect on humans over the past 1000 years. Uh huh. We can look at describing the human um niche um is that the human niche when it comes to the environment is that they control their own I mean we control our own um competitors um presentation, pests, parasites and diseases which reduces the um because constraints that these biological structures exert on. And also We'll have in the past 1000 years. Well, the niche of the industrial humans which is us um from domestication of fire and animals developments Of tools, agricultural methods did increase the population, but when science and technology came in it did cause the human population to grow quickly. Where in 1995 almost six billion people were alive on earth. So yes, that's really an interesting factor about humans. And yeah, that is it. I hope you found this very helpful and please feel free to look at your content from other creators that go over and explain whatever attractive questions you need extra help with. Okay.

You guys, the four of this question There's really endless answers. I'm just going to go over a few that are all different. Um, distribution Examples of what we do is humans, too. I'm destroyed habitats, so one of them would be fast fashion. Yeah, and essentially like manufacturing go goods in general. But I will say non essential goods because there's a difference between us manufacturing food and US Munich directory. He's like new fashion trends. Eso fast fashion, specifically is different, obviously loads because being from really cheap materials, generally they don't last this long, so it's not. You could recycle them were they go home, be able to have, like multiple different owners are lost a long time. So even if he's in the drifts or they're probably acting last very long because Sullivan should get a holes about sexual breakdown, those kind of things. So the way that this shorts habitat is getting getting resources to make thes um, cooling items, pollution from factories and fracturing no one of the EU's, the car would end up in the trash of the garbage they go landfills, which also contribute to destruction of privatised, this kind of thing so Ah, well, uh, manufacturing in general. But I specifically book some fast fashion. That's one thing that really he's I don't don't last very long there really, really unnecessary. There are other clothing items that you can get and that won't cause much environmental destruction. Another human activity that just true seekers it sounds, is and taking away natural resource is especially game, huh? Looking for a tropical wood from like reinforcing those kind of things. Um, also put in here palm oil because that is your soul singing destruction of a lot of the crane for us and then just in generally in general, like forest and great first destruction for the land. For those guys, do you know they're mentioned as well? So, basically is trying to get natural resources and destroying George areas of trees for us, those kind of things to get wood oil or make room for buildings and those kind of things as well. And then another one would be pollution of waters. So no, only pollution that goes like the area and everything but polluting waters and those kind of things is really the detrimental because fish can't live in there anymore. and any of those kind of aquatic organisms full struggle to survive, and it also takes away other organisms. Source of water Rich is very necessary, and you can not drink water. You could present really find something else to eat if you're bearing the lead fish, but you're not going to build it. Just thought an alternate alternative to water but finding their water source. But there's no alternative to water, so that is another. Well, it can. Do you consider destruction of a, um, How is that? Because, you know, we're not like getting rid of the water. We're still destroying that what are making on drinkable or unlivable. And then the lesson is like agriculture, then using lands for forming on those kind of things because other we are stroh may be great for growing plants and stuff in that land. That doesn't mean that's what was originally there. So for creating clearing land to use for, um forming on those kind of things like you mean plans. You are pointing your plants there, but having just like acres and acres and acres of corn is different from having acres of curry or forests or those kind of things where you have a lot of different organisms, a lot of different plans, a lot of those kind of things growing in on areas supposedly one plant. And then there are some animals in those kind of things that console it there. But the, um, those are protrude farm, those kind of things. They're also treated with a lot of pesticides, fertilizers, those kind of things that complete waters it can take. You be toxic to animals. There's gonna big city is also destroying their source of food, and there's or so think where they live. And they're How's that?

So two ways that I thought, Oh, for science to be able to be misused would be biological warfare where chemists will actually, or chemist or your biologists or other die interests come up with something that is used to hurt people. Another misuse of science would be arson. We can use combustion for good things, like heating our homes and cooking our food. But when you use it to burn down something that, um, you know, that that shouldn't be burned in a criminal way, I feel as though that is a misuse of science.

So when talking about human impact on earth really are so many different things that we can talk about much beyond, you know, the time we have to talk about in this video. Um so the way I will approach it here is to kind of briefly know a couple of things for each of the four earth spheres uh we can approach as part of earth's systems. Thinking so if we first think, say of the lift a sphere, right, some human impacts to this on the little sphere, we can think of things like mining, alright, extraction of many earth materials that people are interested in using for various reasons, right altering uh topography um of earth's surface, moving earth materials around, you know, a gravel mining and extraction using for paving of roads. For example, all these types of activities are affecting our little sphere, earth's crust, the atmosphere, right? Being next our second earth sphere here, I want to talk about the atmosphere and thinking of things like air pollutants that get released through various um human activities. Um uh you know, pollutants could have also been dumped into the little sphere as as well, but oftentimes air pollutants thing of uh tighter things. Like of course global climate change, all these aspects that are important and around our atmosphere third our hydro sphere. So when we think about earth water right? Talking about changing water flows across earth's so tight of things like dams right on rivers, um things like groundwater extraction and use um and depleting of aquifers underground. Um so all these types of things, how we have affected um our hydro sphere and then finally, of course our biosphere our last sphere here, how humans have affected, are there life on earth? Right? We have human interaction leading to write the reduction of biodiversity, right? Or that kind of extinction of certain species. It's just as one example there, right of how humans are interacting with our biosphere is there again, there's there's really many more types of examples we could put here. There's just a few to get us started thinking about various types of ways and all of these earths fears that we think about how humans have interacted and changed had a big impact in a magnitude wise on our earth.
