好難啊!!!!點做啊?

1. Select and flag the trees to be saved.

2. Select and prominently mark the trees to be removed. However, some of these trees may make a natural barrier for trees to be saved. You can let them remain until after construction.

Trees to be removed that are growing near trees to be saved should be cut off flush with the soil or their stumps ground out rather than pulling them or digging them with a backhoe. Using a backhoe may compact the soil around the trees to be saved. Because the roots will be entwined, pulling out the stumps would damage the roots of trees to be saved.

Trunks of deciduous trees to be saved may need a thin coat of whitewash to protect them from the possibility of sunscald from new amount of sunlight.

3. Build a barrier around the protection zone of trees to be saved.

1. plant more trees
2. stop cutting trees
3. use less paper
4. recycle the paper

We can make some bamboo around trees to prevent some insects's attack.１
