If we disconnect from the natural world, we become disconnected from who we are — to the detriment of our health and the health of the ecosystems on which our well-being and survival depend. Understanding that we’re part of nature and acting on that understanding makes us healthier and happier and encourages us to care for the natural systems around us. A Toronto-based study, published in Nature and co-authored by a team, including University of Chicago psychologists Omid Kardan and Marc Berman and David Suzuki Foundation scientist Faisal Moola, examined the relationship between urban trees and human health. The other study, published in Ecosystem Services and co-authored by scientists from the U.S. According to the Toronto study, adding 10 or more trees to a city block offered benefits to individuals equivalent to earning $10,000 more a year, moving to a neighbourhood with $10,000 higher median income or being seven years younger. Science is giving us a better understanding of the many ways natural spaces can improve the lives of humans and how connecting with nature improves our desire to protect our surroundings. In nature, termites have the important job of returning the nutrients in dead trees to the earth. Although less common than subterranean termites, drywood termites (family Kalotermitidae) are also found in in Texas. All termites are social insects that live in advanced colonies composed of as many as four castes.
In general, we use some combination of direct wood treatment, soil treatments using non-repellent termiticides, and foaming of wall voids and other structural voids. A majority of the world's savannahs are located in Africa, but they can also be found in South America, India, and Australia. Nearer the equator the heavy rainfall during the wet season, and the fairly high total amount of rainfall during the dry season encourages vegetation to grow.

Predator-prey relationship - In ecology, predation describes a biological interaction where a predator (an organism that is hunting) feeds on its prey, the organism that is attacked.Predators may or may not kill their prey prior to feeding on them, but the act of predation always results in the death of the prey. Parasitism - Parasitism is a type of symbiotic relationship between two different organisms where one organism, the parasite, takes from the host, sometimes for a prolonged time. Mutualism - Mutualism is a biological interaction between two organisms, where each individual derives a fitness benefit, for example increased survivorship. The two more common species are the Eastern subterranean termite (Reticulitermes flavipes, shown on the right) and the Formosan subterranean termite (Coptotermes formosanus). Unfortunately, termites make no distinction between dead trees and the wood in our homes and other buildings, resulting in an estimated total cost of $5 billion every year in the U.S.
All termite colonies have reproductives (the queen and king, and sometimes supplemental reproductives) and workers, who are the caste that actually eat wood and do the damage. But now, sporadic droughts, soil erosion and overgrazing are tiring the land out, while demands on it from impoverished human populations continue to grow. These are climate, edaphic, hydrological and geomorphologic factors, fire and grazing (Bourliere and Hadley 1992). Permanent settlement is limited by the long dry season, uncertain rainfall, and poor soils.
Most colonies more than a year or two old also have soldiers, whose job it is to protect the colony; and mature colonies produce alates, or winged reproductives (often called swarmers) who will leave the colony to establish a new one. All of our work is warranted, and the warranty is transferable to the new owners if you decide to sell your home. Overgrazing and cultivation of marginal soils already low in plant nutrients are destroying what were once rich farming lands.

Less than 80 mm (3 in) of rain falls each month between August and March (usually considerably less, and often none), but this shoots up to 350 mm (14 in) or more in June and July. Away from the equator, vegetation in the form of trees and poor quality grasses are only found near rivers and water holes. They eat wood, building mud shelter tubes between the soil and the wood if there is any space between the two.
Very often the alates (or their shed wings) are the first evidence of a termite problem that homeowners see. In the savannahs, trees are cut down over a large area and then stacked on fields, where they are burned. Like subterranean termites, if left untreated, drywood termites can literally destroy a wooden house.
Crops like sorghum, millet, and cassava are grown for several years, until the soil is exhausted.
In places where cattle are raised, fertilizer is used to prolong the fertility of the soil, but pests, disease, and drought cause many problems. Many farmers and herders are moving from the savannahs towards the South to port cities in search of work.
