Repairing trees. From the reference below:
Like all living things, trees are subject to disease, decay, and death. When a tree is wounded, fungus spores lodge in the wound, germinate, and send out creeping threads that attack the living cells and tissues. In time it dies unless a tree surgeon saves it. Until the time of John Davey in 1880, tree surgery was an almost unknown science.
The process of repair is in some respects like dental work. First the rotted wood is removed and the cavity cleaned, sterilized with a chemical, and waterproofed with tar or asphalt. Shaping the cavity requires expert knowledge. Shallow cavities are usually left unfilled; weak cavities are mechanically braced. Under certain conditions cavities are filled with asphalt or wood or cement mixtures installed in sections to allow for the natural swaying of the tree. The bark gradually grows inward and heals the wound. Injured branches are treated similarly. Scars must be sterilized, shellacked, and waterproofed.

concept i might throw my hat interior the hoop by ability of asserting, the reason they spend lots on plastic surgical technique is the medical doctors fee way too lots, and that they does not choose plastic surgical technique if society wasn't so judgmental on how human beings seem. We as a society have created this difficulty alongside with many others, and once you communicate approximately how lots you have given and boast approximately it, you have merely have been given your reward as Christianity teaches, so no i does not shop on with on your footsteps, it fairly is sin in accordance to the Bible. On a fact experience i will tell if the wealthy or properly to do helped the undesirable and needy, we'd all merely be mediocre, and that's particularly like communism, some thing i'm to not mad approximately, yet wait you probably did not say the undesirable might ought to artwork we'd merely supply it to them and help them out. i think of we already try this, its referred to as social guidance and our taxes cover that fee alongside with producing jobs for social workers. So we are already giving to the undesirable, we merely are actually not boasting with regard to the solid we are doing. actual charity comes from the middle and is not measured by ability of the media and what others think of, that's carried out in secret so which you do not humiliate the needy or crown the giver.
