The biosphere is as important as life itself because it is all of life. Without the biosphere, the Earth would be a lifeless planet such as Mars or Venus.

Life is fragile. Because the biosphere is made up of all life, it too is fragile. Humans can have a huge impact on the biosphere, in both good and bad ways. The growth of the human population on Earth means there is less room for other species. Because of this, many types of plants and animals have been partially or completely wiped out. The biosphere is important to people because we can have such a profound impact on it.

I believe the biosphere is fragile, because over time all of the pollution us humans have made; If its from air pulloution, acid rain or even water pollution. the toxic acids over time have made the biosphere and the ozon layer weaker and more thin. which causes the biosphere to become weaker.
