The greatest threats to the sustainable development on earth are: population growth and urbanisation, energy use and global warming , excessive waste generation and the subsequent pollution of soil, air, and water, transportation in cities, and limited supply of resources. Many of them are interrelated.
What are the threats of humans to environmental sustainability?
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.
