9 reasons to be thankful for plants

This Thanksgiving, remember how important plants are to our lives.

November 21, 2017

Why should we care about plants? As a plant conservation biologist, I get asked that question a lot! Try as I might, I’m not sure I ever adequately convey how important plants are to virtually every aspect of our life. Like to breathe? Thank a plant! Eat? Thank a plant! Here are just a few reasons we should thank a plant this month.

  1. Oxygen

Plants create the oxygen in our atmosphere through photosynthesis. They (along with some photosynthetic bacteria) are solely responsible for providing the air we breathe.

  1. Food 

Virtually all food comes directly or indirectly from plants. The fruits and veggies at the farmer’s market, sugar and flour in our baked goods, meat and dairy products from animals that required forage, and even mushrooms that required plants to supply their energy - it all starts with plants. 

  1. Medicine

Most medicines are originally isolated from plants (and some fungi too). Examples of important drugs coming from plants include aspirin from willow bark and the potent cancer fighting drugs, taxol from a yew tree and vincristine from a periwinkle plant.

  1. Fuel 

Plants have been used to heat our homes and cook our food since the dawn of civilization. Some plants are used directly for fuel, such as wood and peat for fireplaces and stoves. Fossil fuels, like coal and oil, are largely derived from plants that lived millions of years ago.
