For several years now scientists and engineers have been able to grow animal tissue in labs by starting with basic cells. Same idea is applied to plants. This might have a dramatic effect in helping to stop deforestation on earth if we can grow and 3D print all the wood products we need for paper, wax, medicines, rubber, furniture and more. Perhaps even my favorite: hardwood for fuel on cold winter nights! 

Three cheers to the scientists and engineers who are helping to make the world a better place every day.
