Growing coffee beans is a huge, making-money business. However, unluckily, full-sun production is replacing the industry and causes a lot of damage. The change in growing coffee from shade-grown(荫下栽种) production to full-sun production brings certain animals and birds in danger, and even breaks the world’s ecological balance(生态平衡).

On a local level, the damage of the forest that is required by full-sun fields affects the area’s birds and animals. The shade of the forest trees gives a home to birds and other species which depend on the trees’ flowers and fruits. Full-sun coffee growers destroy this forest home. As a result, many species are quickly in extinction.

On a more global level, the damage to the rainforest for full-sun coffee fields also does harm to human life. Medical research often makes use of the forests’ plant and animal life, and the ruin of such species could keep researchers from finding ways for certain diseases. In addition, new coffee-growing methods are harmful to the water locally, and lastly the world’s groundwater.

Both locally and globally, the continued spread of full-sun coffee plantations(种植园)could mean breaking the balance of the rainforest ecology. The loss of shade trees is already causing a little change in the world’s climate(气候), and studies show that the loss of oxygen-giving trees also leads to air pollution and global warming. Besides, the new growing methods are bringing about acidic (酸性) soil conditions.

It is clear that the way much coffee is grown affects a lot, from the local environment to the global ecology. But coffee users do have a choice. They can buy shade-grown coffee whenever possible, although at a higher cost. The future health of the planet and mankind is surely worth more than an inexpensive cup of coffee.
