Detailed explanation-1: -The total global population is more than seven billion people. Still, there is a consistent increase in the overall earth populace and this has been a critical factor in accelerating the depletion of natural resources.

Detailed explanation-2: -Impacts from human activity on land and in the water can influence ecosystems profoundly. Climate change, ocean acidification, permafrost melting, habitat loss, eutrophication, stormwater runoff, air pollution, contaminants, and invasive species are among many problems facing ecosystems.

Detailed explanation-3: -Air Pollution, water pollution, solid wastes, agrochemicals, radioactive wastes, greenhouse effect and global warming, ozone depletion, improper resource utilisation and deforestation are some of the main causes of depletion of natural resources.

Detailed explanation-4: -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.
