Considering how large of a GDP the US have, I would agree with such a move. There's several reasons why I would agree on such a move. One of them is of course the well being of the nature, as it is crucial for the survival of every living organism, including the humans. Reforestation will bring in lot of benefits that will gradually return the investment. For starters, the air quality will improve, and by doing so, the health problems among the people will reduce significantly, thus much less will be spent on healthcare. Part of the new forests can be fruit forests, which will be an enormous reserve of organic food without having to use any labor or effort in production. Also, by establishing forests, whole ecosystems will get back on the scene, so lot of useful plants can be harvested from the forests, such as herbs and mushrooms. If the US makes a deal so that it can use certain part of the benefits from the forests until it gets its enormous investment, it will be a win-win situation for everyone. In order to have the budget for the global reforestation, it would be the best to cut down on the budget for development of weapon of mass destruction and the budget for war.
The United Kingdom is the answer :)
This area is located on a convergent plate boundary where oceanic crust collides with continental crust. Because the oceanic crust is more dense, it sinks into the ground and heats up. It thus becomes a volcano as it rises back to the surface. This process is known as subduction.
Water rights people fight over water rights all the time. Cause water is valuable and people want to save the water. Lots of arguments or water rights
