Humans can affect the environment in the following ways:
-
by adding greenhouse gases to the atmosphere: This contributes to climate change and global warming.
-
by using natural resources: The extraction and consumption of resources can lead to habitat destruction, resource depletion, and biodiversity loss.
-
by polluting the land, water, and air: Pollution from industrial activities, agriculture, and waste can have harmful effects on ecosystems and human health.
-
by creating landfills: Landfills can contribute to soil and water contamination, as well as produce greenhouse gases like methane.
-
by introducing invasive species to the environment: Invasive species can outcompete native species, disrupt ecosystems, and lead to biodiversity loss.
The option by using sustainable resources is generally seen as a positive action rather than a negative impact. However, it's important to note that even sustainable resource use can have localized environmental impacts if not managed properly.
In summary, the actions listed (except for using sustainable resources) are ways humans might negatively impact the environment.
