Humans always influence and create the physical characteristics of the earth by the structures they build and by their activities.

is this true or false

false

Explanation:

The humans indeed have big influence on the physical characteristics on the surface of Earth, but it can not be said that the humans always change the Earth with their activities and structures they build. For starters, there are lot of human initiatives that are actually forbidding any changes of the physical features of Earth, as they are seen as valuable, beautiful, or natural treasure. Also, the humans are not the main factor influencing the changes on Earth, but it is the natural processes that cause the changes on the surface of our planet and create its physical features. Such processes are the volcanoes, erosion, weathering, water, and even the space objects that fall on our planet. As the human population is increasing though, it is expected that the human influence will be increasing more and more, and that can lead to a situation where the humans do actually become almost as influential as the natural factors, which would not be good at all.
