What is the conclusion of the human impact? give me at least 3 sentences.

Human impact on the environment or anthropogenic impact on the environment includes impacts on biophysical environments, biodiversity, and other resources. The term anthropogenic designates an effect or object resulting from human activity. humans poluute,make things that damage the ozone layer. Deforestation has become a huge concern for a wile, we over populate the earth and we change the Environmental behavior because the floods and dams we create.

Humans have a bigger impact on the world than you might think. 

Kinetic energy = 1/2mv^2. since the mass is constant we can form a ratio of it's kinetic energy at 60 divided by that at 30 to see ke(60)/ke(30) = +(60^2)/30^2). this may be said to 300% increase.
