ESS3C - Human Impacts on Earth Systems
In this video Paul Andersen explains how humans are impacting the Earth through farming, mining, pollution and climate change. According to the NGSS wise management can reduce impacts on the planet. This will become more important as developing countries start consuming more resources. A K-12 teaching progression is also included.

Then and Now: Human Impacts on The Earth System
Looking at your childhood pictures can be alarming (“wow, I wore my hair like that?”). Similarly, looking at snapshots of our planet through time gives us an idea of the changing human impacts on the Earth system. Photos from NASA’s Landsat satellite have given us an unmatched views of human impacts on Earth, from changing global climate to resource availability. However, not all human impacts are negative – for example, our cities and nation are switching to energy sources that are renewable and do not emit heat-trapping gases. This short video ultimately shows us a changing planet with a new focus: sustainability and resilience. Try to imagine what photos of the Earth may look like in another 20 years.

Human impacts on Biodiversity | Biology for All | FuseSchool
Biodiversity is the variety of life.
There are thought to be 8.7 million species on planet Earth. And, as we saw in this video, biodiversity is of utmost importance to humans.
The loss of one key species can have a detrimental impact on many levels; from other species of animals to plants to the physical environment, as shown by wolves.
Human activities are reducing biodiversity. Our future depends upon maintaining a good level of biodiversity, and so we need to start taking measures to try and stop the reduction.
In this video we are going to look at how humans are negatively impacting biodiversity.
As the world population has grown from 1.5 billion in 1900 to nearly 7.5 billion people today, unsurprisingly the land use has changed.
Habitats have been destroyed in favour of agriculture, forestry, fishing, urbanisation and manufacturing. Unsurprisingly, habitat loss has greatly reduced the species richness. Habitat fragmentation has also meant that populations have been split into smaller subunits, which then when faced with challenging circumstances have not been able to adapt and survive.
After habitat loss, overharvesting has had a huge effect on biodiversity. Humans historically exploit plant and animal species for short-term profit. If a resource is profitable, we develop more efficient methods of harvesting it, inevitably depleting the resource. As is currently happening with fishing and logging. The exploited species then needs protection. The difficulty is that the demand then outstrips the supply, and so the resource value rises. This increases the incentive to extract the resource and leads to the final collapse of the population. As happened with whales, elephants, spotted cats, cod, tuna and many more species.
Human activities are polluting the air and water.
Toxic discharge into the water from industrial processes unsurprisingly has a negative effect on the local aquatic species by killing, weakening or affecting their ability to reproduce.
Phosphorous and nitrogen in fertilisers run-off agricultural fields and pass into rivers. These surplus nutrients cause algae to bloom, which then starves other aquatic species of oxygen and light, causing them to die.
Acid rain is one consequence of humans polluting the air. This causes lakes and water bodies to become more acidic, killing off fish, molluscs, amphibians and many other species.
Huge impact humans have had on planet Earth is the introduction of alien species to habitats. In fact, it is estimated that on any given day there are 3000 species in transit aboard ocean-going vessels!
Alien species can cause problems in a number of ways… pause the video and have a look.
Throughout the earth’s history there have been periods of rapid climate change, that have led to mass extinction events. We are currently in a period of fluctuating climate, but nearly all scientists agree that human activities, like burning fossil fuels, are speeding up global warming.
We don’t know how much climate change is going to affect biodiversity in future, but it’s predicted to be huge. Loss of sea ice and ocean acidification are already causing huge reductions in biodiversity. Climate change alters temperature and weather patterns, with changing patterns of rainfall and drought expected to have significant impacts on biodiversity.
So there we have a selection of human-related impacts on biodiversity. There are much more, which a quick search on the internet will bring up.

Anthropocene: the age of human impact on Earth | Sustainability
You probably know the Cenozoic, Mesozoic or Paleozoic, but have you heard about the Anthropocene? For the last two hundred years humankind has caused such a negative footprint on the environment that some scientists describe it as a new geological age: the age of human impact on Earth or the Anthropocene.
Since the pre-industrial era, and especially since the second half of the last century, the degradation of the environment and the climate change caused by humans have increased at a rate never seen in any other time in history.

How Do Humans Affect The Environment
It's interesting to note that modern humans have been around for a very long time and lived for much of it without causing much irreparable damage to the environment. However, over exploitation and pollution have started affecting the environment negatively over the last few centuries.
