Toucan or Toucan't?

Toucan is my favorite bird. Its beak is like a rainbow. Deforestation, global warming, habitat change and hence the northward movement of these birds will destroy their homes. Everybody needs a home. Homelessness leads to disease and misery and in the case of birds, it means extinction. Burning of fossil fuels leads to acid rain which further hurts my lovely feathered friends. My mom told me by the year 2100, global warming can be 1.1 to 6.5-degree Celsius which can mean the extinction of 100 to 2500 land birds. I will pray that when I grow up I can still see my Toucans and they never become "TOUCAN'TS".
