Another way human activities affect Earth's systems is by using too much natural resources. There are two types of natural resources, renewable and nonrenewable. Renewable resources are resources that do come back within our lifetime and nonrenewable resources are resources that do not come back within our lifetime. We use a lot of both of these types of resources but we mostly use nonrenewable resources like gold, copper, and natural gas. These resources are also not healthy for the environment. Humans need to learn how to use more renewable resources so that Earth can have a better system and last longer.

A carbon footprint is a mark you leave behind or a way you change Earth in a negative way. Humans leave behind carbon footprints all the time. They contribute carbon footprints in their daily lives. Some examples are when you leave the lights on when not in the room. Cutting down trees, eating a lot of meat, driving automobiles, buying things we don't need, throwing away reusable things, building factories, and over using fossil fuels like coal, oil, and natural gas.

Causal is a relationship where one variable directly causes the other variable to change. Correlation is a relationship between two variables that may be indirectly linked but one does not cause the change in the other. Lots of human activities are causal actions and some are correlational actions. For example in a national park, as a causal action, if humans get rid of all the wolves in the park, then there will be a higher elk population because wolves eat elk. As a correlation action, if humans reintroduce wolves to the park and then more Aspen tree grow it does not mean that the wolves are the reason why the population of Aspen tree increased.

The green house effect is caused mostly by human activities. Some of these activities include driving, polluting, and burning fossil fuels. These actions cause there to be an extra layer of Co2 in the atmosphere. The Co2 then absorbs and reflects sun light causing the earth´s atmosphere to become hot.

Humans have effected the environment by creating excess green house gasses, in turn of creating the excess gasses the world is getting hotter which we call global warming, which makes it harder for some animals to live like penguins for example it may not seem like much if the temperature only goes up one or two Celsius but for the arctic it is traumatizing like for example the penguins need ice to live on and krill need ice to feed on the algae on the bottom of the ice, and with krill depleting because of fisheries and other creatures eating them that is making some species go down as well.

There are many things Humans could do to affect earth systems like driving cars when we do i makes gas and it breaks down the ozone layer or when we use a factory i make so much gas it goes up in the air and so it could hurt eart

A lot on how human activities affect Earth's systems, is how we contribute to polluting the air. By driving everywhere can pollute the air, also not recycling is bad for the earth trash just build up in landfills and doesn't go anywhere. also over using our natural resource. ton of our water is going to waste, and by keeping the light on light while your not in a room. or blasting the heat could cost you a lot of money and is wasting or natural resources.

natural resources are organic elements used by humans that is normally found in the ground.

Humans affect the Earth's systems because of many different reasons. One reason is greenhouse gases. Greenhouse gasses affect the Earth's system by releasing heat. So the temperature will rise. A few ways you could be participating to make this happen is driving cars, burning coal. Also the heat can turn into radiation. The reason why is because of all the CO2 gasses.

Human activities affect Earth's systems by the greenhouse effect. The greenhouse effect is the trapping of sun's warmth in Earth's atmosphere because of the transparency of the atmosphere from the sun's radiation. The greenhouse effect use to be a good thing but now it is not because it is warming up the Earth too much and causing global warming. But without the greenhouse effect, the Earth would be just like the moon. One side of the moon is extremely hot and one side of the moon is extremely cold because it has no greenhouse effect controlling the atmosphere and bringing in the right amount of temperatures.

There are many things that humans change because of their activities. Humans take part in why earths temperatures change so much. They have a part in temperature change because when we make things in factories that make co2 and that co2 makes it were the suns heat and gases bounce of the co2 and back into the earth. When humans affect earths systems they have created the greenhouse affect. The greenhouse affect is where all of the sun's heat and radiation goes into the earths atsmophere it can't leave hence making the world hot and humid just like a greenhouse. A lot of this happen because people use cars, make things in factories, and just pretty much when anyone messes with fossil fuels.
