How do we know ?

How do we know there is a problem caused by human impact? Once we know there is a problem, how do we know if it is getting better or worse?

You can tell if it is getting better or worse when there is less of it happening .

Global warming is caused by human impact it is mainly caused by the burning of fossil fuels witch release greenhouse gases we can monitor it by using satellites to see how much ice goes away per year.

One problem is extinction. We know that we are causing this because animals are dying from our causes. Oil spills kill many animals. We hunt some to extinction, and drive them away from their habitats. We know that this problem is getting worse because we can look out side one day and see several types of birds, or other animals. A few years later, we can do the same thing, and there will likely be only a few birds or animals.

We know there is a problem caused by humans when the problem could only be caused by humans and we know it is getting better or worse when it dies down or if it gets alot bigger over time.

Olivia M said...

We know that there is a problem caused by humans when we see a fire and we know that its getting better when it the problem stops or slows down. We know when it is increasing and spreading rapidly.

Jared S said...

We know because of all the damage that has been done. We know if its getting better or worse because we count how wildfires there are and test them to see if it was a natural disaster or globel warming.

When we extract and burn fossil fuels such as coal or petroleum, we cause the release of carbon dioxide (CO2) and other heat-trapping "greenhouse gases" into the atmosphere.

But wild fire sometimes are caused by humans and sometimes by the sun.

Aquifers provide us freshwater that makes up for surface water lost from drought-depleted lakes, rivers, and reservoirs. We are drawing down these hidden, mostly nonrenewable groundwater supplies at unsustainable rates in the western United States and in several dry regions globally, threatening our future.

when there is mud slides we can tell it is caused by a human when there is a house on a side of a hill.

We know that there is a problem caused by human impact because of the satellites out around the earth.We can know if the problem is getting worse with the kind of tech we have today

How we know that there's a problem with human impact is that animals are dying. Whether its from cutting down trees of polluting oceans, animals are always dying. How we could find out if the problem was getting better was by having scientists check the water monthly and see if it was getting cleaner and for cutting down trees, have cameras up on weekly monitors to make sure that no one is cutting down trees where they aren't suppose to.

We know about the causes humans have the environment because it is easily visible that a human caused something, a form of this would be leaving a simple cigarette behind at the scene of a forest fire. Or maybe some fingerprints on some trash that has been lazily thrown into the lake. Once we know about it, we have to know if it's better or worse, one way for a forest fire is that I believe that firefighters keep track of their missions. Then they add up the rate of forest fires per year.

We know when there is a problem caused by human impact because people can tell if the fire was lit by a lighter and we have monitors that can help prevent human impact. Once we know there is a problem we know if it is getting better or by

Some human-caused fires result from campfires left unattended, the burning of debris, negligently discarded cigarettes.

Kristina said...

We know there is a problem with human impact because the animal death rate is going up because of polliton

We know that a problem is caused by human impact because people do all the things like mining non-renewable resources and losing all of the resources we need to survive like heat. We know if its getting worse because it is getting lower like non-renewable resources.

Aaron Mills said...

We know if there is a problem caused by human impact, because we can watch the news, and the News Reporters will let us know. We will know if it will get better or worse by watching the news every day.

dillon said...

Well there is a problem when 99% of wildfires are because of humans so we burn some
of the woods then water it down so theres a lower chance of another wildfire happening
thats a way to know thats its getting better.

when people cut down trees to make lumber it takes away more air

e now when there is a problem when the animal population goes down for wild fires.

Jade S said...

Some animals will rome around and try to find a new home because someone burned it down. We can see if it is getting better if we see less animals walking around looking for a new home and we can see if it is getting worse if we see more animals walking around.

matthew said...

we know there is a problem caused by human impact when the problem is caused by human ignorance. Once we know there is a probleme know if it is getting better or worse because if it is getting bigger or if it dies down over a long time.

Most Everyone uses technology and machines that could pollute the air. We know if its getting better or worse if we see signs of it going away, smog can thin out and go away, If it wasn't going away it might get thicker.

How we know is by the green house affect.We can tell if it is getting better or worse by using satellites to measure the amount of the gases.

How we know is that if the earth is getting worse is if we feel its getting hotter in winter

Alicia said...

By monitoring.

Tim D said...

We know there is a problem because the the amount of gasses making the air dirty and plants die.I think we could fix this by reducing the amount of fuel burned.

Jakob P said...

Every time we cut a tree down it take away a little bit of air to breath.

Chris Payeur said...

A positive thing human impact has had is medicine and a negative thing they did is pollution.

Samples

Wayne Twombly said...

Pollution is a problem with us Because the water is getting polluted along with the air but know its getting better because we are developing eco friendly cars and stuff to not pollute.

Cameron M. said...

We cause pollution you can tell there is pollution by putting something in the water. You can tell if it is getting better if the animals start too come back.

Kevin D. said...

We know if there is a problem by using machines to check it.
We know if it is getting better or worse by monitoring it.

Jacob Varney said...

When there are forrest fires, they are sometimes caused by people leaving fires lit or dropping cigaretes that are lit in dry areas.

haley marsico said...

Once we know that there is a problem we can run tests to see if it has gotten worse or better. And to solve the problem(s) there are different things to do for different problems.

Hannah Perkins said...

You would know if a problem is getting better or worse if you checked up on the problem once in a while.

Kiara M. said...

We know that there is endangered animals by keeping track of how many there are. If the numbers are going down, it is getting worse and we need to do something about it, but if the numbers are going up, we are on the right track.

DARREN A said...

Humans impact the earth in many different ways like land deduction, air pollution, and other things that all impact the earth whether its in a good way or a bad way. Technology can help us tell if these problems are getting better or worse and we have other resources to find these things out to.

Brooke DeCapua said...

A problem is extinction. We kill lots of animals all over the world and bring their population way down. Like with oil spills. People go hunting to kill animals. Or even cutting down trees in the forest and ruining animals habitats so they can't live anymore. We know when it is getting worse when the population goes way down,but we know when it is getting better when the population gets higher.

emily b said...

Oil spills can cause water pollution the pollution can kill animals and plants in the sea.We can tell if the water is still polluted by taking samples of the water in small bottles.

Anonymous said...

Global warming is a sign that air pollution is melting the Arctic.

Anonymous said...

And right now, its getting worse and we know that because the population is getting a lot bigger.

Ryan S. said...

If there was an oil spill in the ocean it would kill fish and plants they would know if it was puoluted by taking samples of the water and testing them.

Dakota Sanborn said...

Littering is bad for the Earth.

Anonymous said...

We could know by if we start noticing effects of the problem, we know if its getting better if we start to notice the effects less.

Anonymous said...

people and animals start dyeing out of no were or theres not as much dead things

Jake Esty said...

We know it is because of humans because of the type of pollution and where it happens and we know if its getting better or worse because of what happens to the wild life and plants around that area.

camden s said...

We can keep track of animals and see if there population is growing or dropping. And we can look at the health of organisms from air pollution and all trees cut down. We will know because things will die.

DYLAN N said...

Cutting down the rain forest will make a lot species go extinct.

Nate P said...

Hunting will keep vegetation in place

Abby D. said...

We know there a human impact problem, like endangered amimals by monitoring or/and tracking the animals

Aidan Farris said...

Global warming is a human impact because we have factories. We know because the smoke from factories.

Megan.A said...

Humans, Impact the world in many way like air pollution and much much more.

Anthony B said...

We know about littering when we find trash or other things on the side of the road. We can tell if the problem is getting better or worse by looking out of your car window.

Isaiah w said...

If people do something stupid like cause oil spills it can kill fish.

Sometimes we could find them with our own eyes and see if it's getting better or worst.

you can tell if it is getting better or worse because i will happen more or less

KOBE DIXON said...

Over two thirds of Earth's surface is covered by water; less than a third is taken up by land. As Earth's population continues to grow, people are putting ever-increasing pressure on the planet's water resources. In a sense, our oceans, rivers, and other inland waters are being "squeezed" by human activities—not so they take up less room, but so their quality is reduced. Poorer water quality means water pollution

David Ross said...

A human impact is like when people hunt and kill all the animals in the area then will be no more so you can't hunt again until there are some and you know when it's getting better when you start seeing animals coming back.

tanya .m said...

You know because most thing you can monitor.

Ana said...

People leave cigarets that cause wildfires, wild land fires, forest fire, vegetation fire, grass fire, peat fire, bushfire, and hill fires.

Tim N said...

We have people that track all the animal.

Antwan M said...

You can tell if Humans are Hurting the Earth, the oil spills can kill fish, the pollution can cause acid rain, and the littering can cause loss of trees/ global warming (When the trash goes into the ocean and gets dissolved by evaporation and goes into the clouds)

Zeke Sturgeon said...

If a corporation goes into a rainforest and starts to cut down trees that could have a major impact on the inviement.You could tell if the species that live their are dying.

Jack B said...

You can tell that the population is getting to big because overtime someone is born the docters write it down that so that is how you can tell and you can tell if it is getting better or worse because they just look at the papers to make sure.

Nicole Printy said...

Animal instinction is a problem made by humans. When we hunt we kill them. They can keep track of this by counting how many of an animal there is in one area at a time.
