Save the rain forest -Huang Qianzhi

Rainforests are some of the world's most ancient and complex ecosystems. They cover a mere 2% of the Earth, yet more than half of all plant and animal species live there. The rainforest is home to creatures as famous as the jaguar and poison dart frog, as well as lesser-known and even unidentified species.
These ecosystems are an amazing resource that is quickly slipping away. The rainforest is where many modern food staples originated, including tomatoes, corn, and chocolate, but we use a mere fraction of the edible plants available there. In addition, one quarter of modern medicines come from plant species that were first used as traditional remedies. Western science has analyzed less than one percent of rainforest plants for medicinal compounds, and the indigenous tribes that use these plants are rapidly disappearing.
To complicate matters more, the rate of species extinction in the rainforest is undeniably high. As the forests are burned for short-term farming, grazed, and harvested for wood and other compounds at an unsustainable rate, we are swiftly losing the very species that may someday provide needed cures or disease-resistant crops. With them, we lose an extraordinary number of unique creatures found nowhere else in the world.
