Humans and Plants
Humans need plants. All animals do. We all needs plants for something basic as breathing as the plants provides us with oxygen which is the air we breathe in and need to survive.Big Time Farming
We have turned to farming as the year progressed and since have manipulated species to create big apples and large ears of corn. The plants would never have done it in the wild. It took man to change the plants. We are also moving toward the genetic alteration of plants. We're trying to make plants that are resistant to disease and bugs. These stronger plants will allow our crops to give us more food from the same amount of space.
Medicines
One of the good examples of plants giving medicine to man is an aloe plant. Inside the leaves of an aloe plant are compounds that soothe burns on our skin. Man also gets something called digitalis from plants. The truly exciting discoveries are in the future. Scientists are analyzing plants every day to find out if they have any compounds that can help humans survive and lead a better life.
And Places to Live
If you live in a house, chances are it was made with wood or there is wood in the house. We have used wood to build our homes for thousands of years. Huge lumber companies grow entire forests to supply the amount of wood needed for our world. As buildings got larger, construction turned to concrete and steel. You will probably still find wood fixtures such as paneling inside these large steel buildings.
