Most people make treehouses using a pile of wood, a hammer, and some nails. Mitchell Joachim, an architect from the Massachusetts Institute of Technology, has a(n) _36_ vision. He pictures a day when homes will be created from __37__.

Joachim's vision ___38__ an idea called pleaching (编织), where tree branches are grown so that they __39__ weave together. Since the growth patterns of trees are  _40_ by wind and sunlight, it may be __41_ to control the way a tree develops.

These Fabricated Tree House Habitats would use trees grown into shapes as housing. One of the __42_ of these designs is that trees would not have to be cut down __43_.

"A 100 percent treehouse would take _44_ to create," Joachim said．__45_ the climate, a house could take anywhere from 5 to 30 years to grow. Fortunately, there's a way to __46_ the process. Joachim suggests including __47_ materials such as sod (草皮), grasses and living branches in the housing designs. "This material would be able to move __48_ the house grows," Joachim said．

A home would become an actual ecosystem, a community of plants, animals, and bacteria working together. The trees would also give off water vapor that would assist in _49__ the homes. Solar panels and wind would help provide  _50__. The tree homes might even have soil pockets, __51_ plants could grow from the structure itself.

Work has already __52_ on Joachim's first design—a house made from 50 percent recycled and 50 percent living things. Joachim is confident about the __53__ of his work, as he uses natural products _54_ nature.

"The environment and its study are very important. We need to respect nature, don’t _55_," he said．

Heavy downpours last month in Rhode Island led to widespread flooding, causing millions of dollars in property damage and leaving thousands homeless. The flood waters also poured vast amounts of raw sewage(未经净化的污水) into the rivers and streams that flow into Narragansett Bay.

It sounds like the makings of an environmental nightmare. But in fact it’s just the opposite. To scientists’ delight. The sewage-loaded floodwaters have caused a well-timed growth of phytoplankton. The microscopic creatures that form the foundation of marine(海洋的) food chains. With more food available for fish. Clams and other sea creatures. The bay’s fisheries industry is expected to benefit.

In decades past. Narragansett Bay typically experienced a late winter early spring algal(海藻) bloom that fed creatures up and down the water column. But in recent years, the waters of Narragansen Bay warmed greatly, meriting this seasonal event.

Mark Berman, an oceanographer with the Nationa. Marine Fishertes Service. Said the flood seemed to have sent the bay back in its normal state.

However, local, mutate and federal officials in Rhode Island leave been batting other algal blooms that, by contrast, are causing widespread harm to the Narragansett Bay ecosystem. During summer months, sewage and agricultural runnel flows into the bay. Causing large blooms. But inseam of becoming food for sea creatures, much of the phytoplankton is consumed by bacteria, which grow last in the warmer waters. The rapid bacteria growth leads to hypoxia decrease of oxygen in the water that can cause large fish tools. One such die-off occurred in 2003. when millions of oxygen-starved fish washed up on the belches of Narragansett Bay.
