Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.
Scientists are now utilizing the samples and data they collected during the Expedition to gain unique insights into how climate change and human populations are affecting even the highest reaches of our planet. Even the highest glaciers on Earth are reeling from human activity around the globe.
Amazonia: The Human Impact. Mining, logging, ranching, agriculture, and oil and gas extraction have put unsustainable pressure on the delicate rain forests of the Amazon Basin.
Climate change is driving down populations of some Arctic tundra natives, such as caribou (also known as reindeer), by fostering an increase in parasites and disease while damaging food sources. But other species, such as shrubs and the wolf spider (Lycosidae spp.), are thriving.
Habitat destruction, defined as the elimination or alteration of the conditions necessary for animals and plants to survive, not only impacts individual species but the health of the global ecosystem. Habitat loss is primarily, though not always, human-caused.
The growth of technology has increased our ability to change a natural landscape. An example of human impact on landscape can be seen along the coastline of the Netherlands. Water from the North Sea was pumped out of certain areas, uncovering the fertile soil below.
Test students’ knowledge of how humans impact the environment through their human footprint, the introduction of invasive species, and the destruction of habitats.
Effects on Humans. People experience a wide range of health effects from being exposed to air pollution. These effects can be broken down into short-term effects and long-term effects. Short-term effects, which may be temporary, include illnesses such as pneumonia or bronchitis.
Heavy rains mixed with the ash fall, collapsing the roofs of houses, schools, businesses, and hospitals in three different provinces. Ash also poses a threat to ecosystems, including people and animals. Carbon dioxide and fluorine, gases that can be toxic to humans, can collect in volcanic ash.
Environmental disasters from 1970 to 2019 led to new developments in science, engineering, and policy. Explore disasters that have occurred over the last fifty years on land, in water, and in the atmosphere, as well as envision solutions to prevent or minimize further disasters.
