A reciprocating saw may be used to chop branches and limbs. You can cut down your tree if it is little enough. Remember that these saws are best suited for cutting stationary material. If your branch or limb has a lot of give, the saw may merely shake it instead of cutting through it. In this case, a pole saw or an ax will be more effective. Tree felling is the process of removing a tree. Tree felling is usually done as part of land clearing or site preparation before building work begins. The person doing the felling may use a chainsaw, a tractor fitted with a bucket loader, or a helicopter equipped with a rope cutter. Less commonly, a backhoe may be used instead. Trees greater than 10 metres (33 feet) in height require a professional to fell them. Smaller trees can be felled by anyone provided they take the proper precautions. It is important to wear protective clothing including eye protection, a face mask, and footwear with protection against thorns and sharp objects. Trees provide many benefits to humans, including timber, food, medicine, and aesthetics. Some people choose to clear forests under their homes to make their gardens or orchards. However, deforestation is a problem because it can lead to soil erosion, global warming, and human-animal conflict. The best way to avoid cutting down trees is not to build your house in forest areas; move if you must build there.
