Review your understanding of human impacts on the environment in this free article aligned to NGSS standards.
- Humans impact the environment through their activities. Examples of human activities include land and water use, deforestation, and the burning of fossil fuels.
- In many cases, the impacts of human activities are negative. For example, when humans clear forests, it causes habitat loss and puts other species at risk.
- Negative human impacts increase as the population grows. They also increase as the average person uses more natural resources.
- Science can help identify solutions to reduce our impacts on the environment. However, it is up to us—as individuals and as a society—to put these solutions into action.

- Global warming is part of the problem but thats not all. Humans over use water for produce, livestock,and humans use water to wash and drink. Does this help?(7 votes)
- Where is the water?(7 votes)
- What you are looking at is the aftermath of illegal logging in the Amazon rainforest. There is likely groundwater in the soil, but the now desolate area you see was once full of lush, exotic trees, plants and brush, all native to only the Amazon rainforest. With the trees, go the animals, either by force or of the animal's choice. This is a very saddening image, because they replace the beautiful tree's they've ripped out, with palm trees, which are not native to the area, nor beneficial to any of the wildlife in the area.
You can flip back to the Khan Academy videos on ecosystems, what has happened here, is human beings have destroyed part of an ecosystem. This is also why it is so important to have good conservation and protection efforts, because you are part of the ecosystem too.(3 votes)

- is there water(2 votes)
- yes. even when a place is completely dried up it usually still has nearby water. the world always has the same amount of water and water is always moving to new places it just isn't always spaced evenly.(5 votes)
- What would happen if people deforested all the forests?6:44pm(1 vote)
- All groups of species would experience massive extinctions, both locally and worldwide. Beyond forests, the wave of extinctions will also affect species that rely on solitary trees and tiny stands of trees. The dangers of deforestation, however, are far worse. Carbon dioxide is absorbed and stored by trees. Carbon dioxide and other greenhouse gases are released when trees are cut down or even just disturbed. The destruction and loss of forests cause around 10% of global warming.
