Human impact

Explanation:

It is normal to the species to disappear, but it is not normal to do so as fast as they do this times.  

The human, and its consumerism that exerts, are the causes of the force extintion of the species. Consumerism is the cause of greater amount of greenhouse gases, erosion due the exesive felling of trees, and for that, lower water retention, and so the water cycle changes.  If the hand of the human changes something of the natural cycle, changes everything

one is through turgidity. this occurs before ground tissue ( collenchyma

and sclerenchyma cells) become well

developed to give structural support to the plant as it grows bigger. the xylem

tissue (composed of rigid tissue) of the young

plant render this support and also maintaining osmotic turgidity of the surrounding

plant cells.
