The physical environment can limit human activities in the following ways:
- Barriers to communication and transportation: most times roads have to be cut through longer distances in order to bypass natural features like a huge mountains, a voluminous river e.t.c. This can severely impact the communication between places and people.
- Natural disasters: The physical environment can pose serious risk to humans through disasters such as earthquake, landslide, flooding, wildfires, e.t.c.
- Drought and famine: When several elements of the physical environment combines, they can lead to little to no rainfall for plant to thrive. This is very dangerous for life on earth. Human activities are connected a lot to how rich and useful a soil can be.
- Climate changes and global warming: Human activities are greatly impacted by changes in climate and weather. If too much rainfalls, it becomes a problem to farmers and human activities as a whole will suffer. If sunshine diminishes abnormally, the earth suffers as solar radiation is very key to life on earth.
